Yamaha Bikes

The YZF-R125 is the most advanced 125 production supersport machine that Yamaha has ever built. This radical, high-revving, fuel-injected 125 is the work of the same engineers who created our legendary YZF-R1 and YZF-R6 supersport bikes. And, as you’d expect, the YZF-R125 is packed with advanced MotoGP technology as well as a whole range of R-series type engine and chassis features.

Its liquid-cooled, 4-stroke, 4-valve, single cylinder, SOHC engine is tuned to deliver free-revving performance right through to maximum power at 9,000rpm – and for instant response and efficient operation this remarkable 6-speed 125 is equipped with a compact fuel injection system. The race-inspired chassis features a Deltabox frame and aluminium swinging arm for outstanding handling performance, and lightweight 5-spoke wheels help to minimize unsprung weight to give impressive roadholding. A large diameter 292mm front disc with a 230mm diameter rear disc make for effective stopping power, and the aggressive R-series bodywork.

Price: $6999.

DESIGN AND STYLING

If you were to compare the YZF-R125 with anything, it’d have to be an early model YZF-R1, the bike that has won many accolades in the litre bike class over the years.

Where many learner-legal rides have somewhat of a ‘cheap’ look and feel to them, this little beauty has quality throughout from the fairing finish all the way to the component strength.

It’s got a superb looking instrument panel, Brembo front brakes seal the deal in the brand name stakes, the low-slung exhaust looks prime, and the race-inspired front ‘number plate’ is a nice touch.

If there’s one thing that does let it down however, you’d have to say it’s the ‘plastic’ feel of the grips – I’d be replacing them on pick-up from the dealer if I was buying one.

As you’ll soon see, the engine performance may not be at the level of the class-leading, top-selling Kawasaki Ninja 250R as you’d expect at half the capacity, but if looking cool is your thing, the Yamaha is top of the LAMS chain, only matched by Aprilia’s RS125 two-stroke.

HANDLING

Handling is where these LAMS-approved models are just so enjoyable, the YZF-R125’s race-inspired Deltabox frame being the heart of a sensational chassis.

At 138 kilograms full of fuel, you can flick the Yamaha around from the outset, something which even the most inexperienced of riders will get the hang of in no time.

The only real problem I can see as far as the chassis goes for young riders is the fact that it’s quite tall for a small capacity machine, but once you’re rolling the relation between the seat, footpegs and handlebars is very forgiving.

Take it through a swift set of bends or ride it through the city on tight 90-degree corners and it’ll react well, the balance of the chassis assisting you in flowing from turn to turn.

The 33mm forks with 130mm of travel will cop most of what the powerful Brembo 292mm disc front brakes can give them when pulling up, but I would have liked to see a little bit of adjustability included.

Meanwhile, the rear monoshock gives the same stiff feel as the front, not feeling springy at all and doing a good job of carrying my experience and 71 kilograms of weight throughout the test without a worry.

Higher quality tyres as standard fitment would only increase this bike’s capabilities, so once you’ve built up some experience then be sure to trade in your cash for some new hoops.

POWER

Engine performance may just be the Achilles heel for the Yamaha as it chases in the wake of its main LAMS competitors including the Kawasaki, however that doesn’t mean you should rule this ride out altogether.

Put simply, the liquid-cooled, four-stroke, four-valve, single-cylinder, SOHC YZF-R125 doesn’t have the power or torque of the Ninja 250R, but it does outshine Honda’s CBR125R at the same capacity.

What the Yamaha does do very well though is deliver the power that it’s got, smoothly applied via the Electronic Fuel Injection system with 28mm throttle bodies.

It’s capable of a top speed of 130km/h if you tuck underneath the paint, which is around 30 kays shy of what its higher capacity 250cc rivals can pull, but well over the Learner speed limit that’s widely enforced.

Yeah, the Aprilia two-stroke may have more juice up top as what is arguably the fastest top-end of the small bores, yet the way the Yamaha’s four-stroke power is delivered is much more consistent.

It’s not really worth much comparing the different engine capacities that we have in the real world, however in the world of LAMS riding once you pass your bike test, it’s these range of options that are going to be appealing to you if you’re in the market for a new small capacity ride.

PERFORMANCE VS. PRACTICALITY

Despite its lack of outright power, there’s no doubt that this bike is a performance-type motorcycle, highlighted by its race-styling and sportsbike-like seating position (although a touch more relaxed).

The seat is comfy enough, vibrations low enough, wind protection good enough and engine capable enough to do reasonable stints in the saddle, but short bursts of sporty riding on the road will likely be your preferred option.

CONCLUSION

I was impressed when I first laid eyes on the Yamaha YZF-R125 on the web, surprised by its size when I picked it up from YMA for testing, and returned the bike as happy as a rider who’s tested Valentino Rossi’s Yamaha YZR-M1 MotoGP racer would be after a couple of weeks in LAMS mode.

What I’m saying is that if you’re a Learner rider working your way into the high-paced world of motorcycling, you’ll feel proud pulling up on the R125, with only the L- or P-plate on the rear being an indication that you’re a newbie on the roads.

If sportsbikes are your forte then this is a very solid breading ground, perhaps a good way to earn your stripes before stepping up to a YZF-R6 supersport once you get your full licence.

I enjoyed my time, and it’s likely that you will to. Just make sure you get a Rossi-replica lid to complete the package of an aspiring sportsbike stalwart.

The XT500 and the model would grow to become the inspiration source for countless variations on the rough-and-macho dual-purpose theme. You could almost say that the whole cult of adventure sports started with this model. People rode XTs — -500s, -550s and -600s — across deserts and trails, raced them (mainly in their TT guise) or simply set about crossing Australia or Patagonia on one, tent and sleeping bag strapped to a sturdy rack.

With the raise in importance of the Paris-Dakar race, parking a “Ténéré” (the so-called ‘race replica’ version with its 7.5 gallon gas tank) in front of a bar or coffee shop in Paris was a proven method to get the chicks, especially if you wore a color-matched off-road jacket lightly spotted with mud stains. Just how big an impact the XT series had at the time can be judged from the fact that for quite a few years, the XT600 used to top European sales hit parades. Gee, how times have changed.

Green parties, angry environmentalists and all the rest of the good-willed gang, have limited access to off-road playing grounds drastically. Much like current SUVs, today’s crop of DPs are far more functional objects that offer a comfy and erect riding position, perfect for relaxed touring and light exploring rather than being proper off-road tackle. So Yamaha’s first redo of the long-running XT series in more than a decade has to deal with a very different world, and it shows.

The tall and lean off-road stance is all there, ditto for the longish suspenders (that any XT500 owner would have sold his sister for), but any serious dirt person would spot the low-slung exhaust pipes, the huge silencers and the almost overly designed body work that shout style above function. It’s hard to blame Yamaha alone on this softening of image. Have a look at current DPs — like Suzuki’s V-Strom 650 or BMW’s F650 — and the shift towards road-only work and worldly comforts is evident. Seen in that light, the new XT660R emerges, at least initially, as the (still) more off-road oriented of the current DP crop. Yes, today’s real macho men ride KTM Adventures or XR650Rs, but these are full-on desert racers with very little disposition for everyday road work.

Technically speaking the XT660R is a mixture of mainly new and a bit of old. If the number 660 sounds familiar to some then its because in the 90′s Yamaha offered a “Super XT” in the shape of the Europe-only, five-valve, water-cooled XTZ660 which also had a full Paris-Dakar style body work with an integral fairing for comfy 100mph flying over dry lakes. Surprisingly, the new 660s top end is all new and the engine reverts to four valves while still being water cooled. Another big change is the new electronic fuel injection system that together with the twin catalytic converters allows the XT to survive in the green third millennium.

I said “old and new” and the reason is that as new as the top end is, I wouldn’t be surprised if the XT’s engine cases mounting bosses would fit straight into an 80′s XT frame. Case side covers have a suitable new design, but it’s hard not to spot the all-too-familiar crankcases sandwiched between them. Claimed horsepower for this mill is 48 horsies, about even with an F650. After decades of closed loop frames in the XT family, the new model gets an open cradle job with the engine cases serving as a stressed member, another sign that the XT isn’t really conceived to handle 20 foot drop-offs. A 43mm Paioli right-way-up fork handles front suspension chores while at the back a standard looking rectangular section swingarm is connected to the shock via a progressive link.

Remember the days when manly men rode XT’s? Almost three long decades ago Yamaha launched the XT500 and the model would grow to become the inspiration source for countless variations on the rough-and-macho dual-purpose theme. You could almost say that the whole cult of adventure sports started with this model. People rode XTs — -500s, -550s and -600s — across deserts and trails, raced them (mainly in their TT guise) or simply set about crossing Australia or Patagonia on one, tent and sleeping bag strapped to a sturdy rack.

The 2011 Yamaha R6 are to be the most exciting bike to ride on the track and the most fun sport bike to ride on winding roads. The engineers tweaked the mid range performance last year but don’t worry, the high rpm rush that has made the Yamaha R6 famous is ready when you are. Confidence, agility, performance and most importantly fun.

The 2011 Yamaha R6 is designed to do one thing extremely well: get around a race track in minimal time. It’s about a screaming, 15,000 rpm plus fuel injected four cylinder engine in a taut chassis that lets it snap from upright to full lean instantly. Oh year: It’s a great street bike too.

Engine

Ultra-compact, lightweight, short stroke, 599cc, DOHC, 16-valve, liquid-cooled, in-line four-cylinder with lightweight titanium valves produces incredible horsepower. Redline is set at an amazing 16,000rpm. 67mm bore and 42.5mm stroke provide a fast revving powerplant. Engine width is minimized thanks to Yamaha’s special casting technologies and “liner less” cylinder design.

Compact “pent roof” cylinder head design features ultra lightweight titanium valves for both intake and exhaust. The intake valve angle is 11.5 degrees and the exhaust is 12.25 degress. The intake valves are 27mm in diameter while the exhaust valves are 23mm. Single intake valve springs reduce weight and “friction” for optimum high rpm performance. The valve retainers are made of lightweight aluminum.

Separate cylinder block (the cylinder is no longer part of the upper crankcase) design utilizes ceramic composite plated “liner less” cylinder bores. The ceramic coating is sprayed directly on the aluminum block. The benefits are greater heat dissipation for consistent power delivery, reduced frictional power loss, reduced oil consumption and since there are no heavy liners, reduced weight too. Lightweight forged pistons feature thin top rings for great high rpm power. The pistons are secured by lightweight tapered type piston pins. The lightweight design means fast engine response.

High Lift / High Performance

Mikuni fuel injection system with 41mm throttle bodies features twin injectors (primary & secondary). This type of twin injector system is also found on our MotoGP M1 machine and the latest generation R1. Each of the injectors utilizes 12 spray holes to maximize the atomization process. The secondary injectors, located inside the airbox, begin to function at mid rpms (6,000 to 7,000rpm) thru to redline. This system is lighter and simpler than the sub motor driven secondary valve type FI system. Special short intake tracts allow for higher rpms and improved power.

Yamaha Chip Control Throttle (YCC-T) is another 1st for Yamaha. This system electronically controls the throttle valves for outstanding response and improved controllability at high rpms. The system features Throttle Position Sensor (TPS) and D.C. motor driven throttle valves. The YCC-T system electronically controls the throttle valves for outstanding response and improved controllability at all rpms. The YCC-T is used to provide even more control of the intake air volume for a smoother torque character. The YCC-T features 3 – ECU’s inside the main ECU to control ignition, fuel injection and the YCC-T. This special ECU is capable of responding to changes at a speed of 1000th of a second.

YCC-I or Yamaha’s Chip Controlled Intake system means the intake funnels / stacks vary in length between 2 pre-set positions depending on engine rpms. The transition rpm is approximately 13,700 rpms. An electronic servo motor varies the funnels. The revolutionary YCC-I provides the best of both worlds …solid low rpm torque and power combined with an amazing high rpm rush. It takes only 0.3 of a second for the funnels to move from the tall to the short position.

Chassis/Suspension

Compact, lightweight aluminum Deltabox frame offers an optimized total rigidity balance for incredibly light and agile handling. This frame is a MotoGP inspired innovation that Yamaha calls a “straight frame concept”. This means the top spars of the frame lie as close to possible to the frame’s torsional axis (the line connecting the head pipe to the swingarm pivot point). The ram air duct passes through the frame at the head pipe for a straight ram air effect too. A mix of revised mold castings and pressed aluminum plates make up the frame. The engine is a fully stressed chassis member allowing for a super-light frame design.

Fully adjustable 41mm inverted front fork provides 120mm (4.7″) of wheel travel and offers incredible suspension performance with ultra-precise feedback. Adjustments include: 5-way spring preload, 4-way high speed compression damping, 20-way low speed compression damping and 25-way rebound damping. The inverted design not only reduces unsprung weight but also increases the rigidity of the fork. The range of adjustments allows the rider to tune suspension to match riding style and conditions.

Upper triple clamp features a 30mm offset for precise handing and great steering feel. The lightweight aluminum clip-ons are mounted below the triple clamp. Fully adjustable Monocross link rear suspension utilizes a piggyback-style shock providing 120mm (4.7″) of wheel travel. Shock adjustments include: 9-steps of spring preload adjustability, 4-way high speed compression damping, 20-way low speed compression damping and 18-way rebound damping adjustability. The piggy back design helps to keep the shock oil cool for more consistent damping.

Radial mount, monoblock, 4-piston calipers squeeze large 310mm dual front discs. The radial mounting design helps to reduce caliper distortion for improved braking performance with excellent control and good lever feedback. The disc carriers are made from aluminium for reduced weight while the sinter metal pads provide incredible stopping power.

Ultra-sleek “new edge form” bodywork features a sharp front profile with centrally located Ram Air duct, engine-revealing side cowlings and ultra-sleek tail section. There are special side fairing intake ducts to allow cool air to circulate around the engine, fuel tank and frame areas. “Minimalism” and “mass forward” movement are two words that best describe this design body. 17.5-litre fuel tank provides excellent rider ergonomics and an aggressive riding position. The reserve portion of the tank is 3.5 liters. The tank features a front tank cover like the R1 and an internal electric fuel pump.

Compact race inspired multi-function digital and analog instrumentation with adjustable back lighting. Features: analog tach, digital speedometer, dual tripmeters, low fuel warning light, fuel tripmeter, and clock. There is also a programmable shift light and stop watch/lap timer that is controlled by the LHS handlebar mounted switch gear.

Immobilizer ignition system is designed to reduce the possibility of “ride away” theft. This system must recognize the “coded ignition key” in order for the unit to start. If the immobilizer ignition does not recognize the key (or a theft’s screwdriver or other type of “jimmy tool”) the bike will not start even if the ignition is turned or forced into the on position. If the system does not recognize the correct coded ignition key, the ignition system and starter will not function.

Additional Features

Adjustable front brake lever

Special 525 lightweight O-ring chain is used to reduce weight

Steering lock

Lightweight aluminum side stand and chain adjusters

Lightweight low maintenance sealed gel-type battery

The YZF-R6 offers a significant level of power and performance. It is not intended for novice or inexperienced riders.

The Yamaha WR250R draws upon over 50 years of Yamaha experience, on pavement and off, to bring you a bike that’ll take you practically anywhere – one hundred percent legally. More power than you might expect flows from its high-tech fuel injected DOHC engine while a hybrid aluminum frame keeps you in complete command.

The WR250R with its fuel injected, 4-valve, liquid-cooled powerplant is ready to shatter the 250 stereotype. From titanium intake valves to its aluminium frame and swingarm, this WR is a highly concentrated dual sport weapon. Whether commuting through city traffic or blazing down your favourite trail, this WR’s is ready to provide uncompromised performance.

Engine

Intake side, lightweight titanium valves and load-reduced springs decrease weight by more than 40% (Vs steel valves). Titanium valves reduce reciprocating mass for faster-revving, plus reduced frictional losses for smoother-hitting power delivery across the rev range. Intake valves are 30mm in diameter, while the steel exhaust valves are 24.5mm in diameter.

The crankcases feature a “tri-axis” design for the crankshaft, main and drive axles. This tri-axis design keeps the crankcases more compact while also centralizing mass for better handling. All of the shafts are positioned low in the cases to maintain a low centre of gravity for great handling and maneuverability. Lightweight, high strength, short-skirt, forged aluminum piston provides great durability and its lightweight design means fast engine response and reduced mechanical vibration.

Engine counterbalancer reduces vibration for improved rider comfort and reduced rider fatigue. This bike can cruise at highway speeds comfortably. Special design high performance camshafts (intake & exhaust) provide outstanding class leading power. The cams feature a WPC (Wonder Process Craft) treatment that increases surface hardness for great durability and reduced sliding resistance. Wet sump lubrication system is used. This system reduces weight and the number of moving parts versus a dry sump system. Piston oil cooler nozzle is used to maintain consistent piston temperatures for durability.

38mm, Mikuni electronic throttle body type fuel injection system is used. This system is a return-less FI system with TPS (throttle position sensor). This system provides excellent throttle response, great fuel economy, reduced emissions and a choke-free design. Throttle response and acceleration are excellent. Long nozzle type 12 hole injector is used and provides a dual spray pattern for excellent fuel atomizationa and best in class performance.

Easy to service 4.1 liter airbox with a new intake control valve provides state of the art intake and emission control. The foam air filter is a washable design. Compact 16 bit ECU features 3D ignition mapping to accommodate the engine power characteristics. The ECU provides optimal timing at all rpms for fast engine response.

Lightweight exhaust system features a stainless steel header pipe and a compact 3-stage expansion type upswept muffler with a honeycomb catalyzer to reduce exhaust emissions. This system maximizes engine power and allows hassle-free replacement of the oil filter. It features a cleanable screen-type spark arrestor. Heat shields protect rider and passenger. The exhaust system also features Yamaha’s EXUP System (Exhaust Ultimate Power Valve). The single butterfly valve prevents the “blow back” phenomenon caused by “valve overlap”. The EXUP system eliminates “flat spots” in the power band and reduces emissions too.

Chassis/Suspension

Lightweight, compact aluminum semi-double-cradle frame features a variety of components. The main frame is cast aluminum, while forged aluminum is used under the main frame below the steering head area and separate detachable down tubes are thin walled high tensile steel. Yamaha has maintained the semi double cradle design to allow for “controlled flex” to optimize suspension action. This frame design provides a low centre of gravity for a light feel and razor sharp handling, plus less rider fatigue, and excellent stability.

Detachable high tensile steel rear sub frame is constructed of round steel pipe. The detachable design provides easy rear suspension access and reduces costs in the event of loop out.

Lightweight, tapered, aluminum swingarm features a mix of extruded, cast and forged parts. The main arms are extruded while the cross member at the front is cast and the rear portion at the chain adjusters are forged. This unique rear arm provides the best rigidity-strength balance plus a dynamic look too. The suspension links are located below the arm to maintain a low center of gravity for razor sharp handling.

46mm, adjustable inverted, Kayaba cartridge fork provide excellent suspension performance. Front wheel travel is 270mm (10.6″). Front fork adjustments include: 19-way compression damping and 17-way rebound damping. Cast aluminum upper triple clamp and forged aluminum lower triple clamp reduces weight and provides excellent strength. The steering stem is light weight aluminum. The fork features a 25mm offset and a 28mm axle offset for great stability and neutral steering characteristics.

Monocross rear suspension system features a fully adjustable, piggy-back style shock. The damping rod is 14mm in diameter while the actual shock body is 46mm in diameter. Rear shock adjustments include: spring preload, 12 way compression damping and 23 way rebound damping. Rear wheel travel is 270mm (10.6″). Link-type rear suspension provides a rising rate (progressive) suspension function. The linkage design is very similar to those used on the YZ/WR competition line-up.

Stainless 250mm fully floating front disc brake with “wave style” rotor is squeezed by a twin piston Nissin caliper fitted with lightweight 27mm aluminum pistons. Nissin front master cylinder features an 11mm piston. Braking performance is excellent. Sintered metal pads are used

Stainless 230mm rear disc utilizes a lightweight “wave style” rotor. The Nissin single piston caliper with 11mm piston and an integrated Nissin rear master cylinder (fluid reservoir is integrated into the top of the master cylinder to reduce weight) delivers strong, progressive stopping power with excellent control and feel. Sintered metal pads are used. Rugged yet light aluminum DID 21″ (21 x 1.60) front and 18″ (18 x 2.15) rear rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance. Straight pull spokes are utilized.

Competition WR series inspired lightweight, digital meter assembly. This compact meter features (basic) are: speedometer, odometer, dual tripmeters, and a clock plus FI system diagnostics in the basic mode. A stopwatch and distance-compensating tripmeter can be found in the “measurement or pace management mode”. Rugged “slim-line” bodywork is very similar to the competition WR counterparts. This “slim line” bodywork allows fast, easy rider movements and a lighter overall machine feel.
