Red Bluff Yamaha
The YAMAHA YZ250
Pure, unadulterated two-stroke genius
The YZ250 delivers the latest in power, response and lightning-quick handling thanks to
continual refinements - super light, super responsive, super choice.
FEATURES
- Our legendary two-stroke Supercross winner is more potent than ever.
- 500 grams off the front end makes this the quickest turning,
best-handling YZ250 ever.
- A light, aluminum frame housing a patented YPVS Power
valve-equipped ripper of an engine results in an awesome power-to-weight ratio.
- Ready to race out-of-the-crate, complete with a ProTaper aluminum
handlebar, titanium footpegs, gripper seat and Excel rims.
|
- New, YZ250F-style front-brake caliper (-220 grams) and light,
wave-type discs (-70 grams) front and (-70 grams) rear remove unsprung weight and provide
excellent stopping power. A new, pushrod-type front master cylinder with a smaller piston
and a redesigned brake lever serve up great feel and braking power.
- Modifying thickness of both inner and outer fork tubes in the 48mm
inverted fork result in a weight reduction of 200 grams. Revised damping settings provide
fantastic bump absorption and comfort.
- A 120-gram lighter fork protector, lighter axle and axle bracket,
lighter wheel collar and the new front brake add up to a 500-gram lighter front
endand even quicker, lighter handling.
- Revised rear shock settings complement the ones in the fork.
|
- 249cc liquid-cooled reed-valve-inducted two-stroke engine is
lightweight, compact and features an incredibly wide, hard-hitting powerband.
- Patented YPVS power-valve system combines crisp, hard-hitting,
bottom-end acceleration with strong midrange and eye-opening top-end.
- Special-design carbon fiber reed-valve petals improve throttle
response and engine performance across the entire rpm range.
- Smooth-shifting, five-speed, close-ratio transmission with
heavy-duty, multiplate clutch.
- Primary kickstarter ensures smooth, easy starting action and reduced
weight.
- Large-capacity radiator features a ten-row core with four louvers
for maximum cooling efficiency.
- 38mm Keihin PWK carburetor with power jet and throttle position
sensor (TPS) ensures precise fuel/air mixing and extra-crisp throttle response throughout
the powerband.
- Digital CDI ignition system delivers precise spark for faster,
stronger response anywhere in the powerband.
- Trick, works-style clutch lever features race-spec barrel adjuster
for on-the-fly adjustability.
|
- A carefully engineered, advanced aluminum frame and swingarm give
the YZ250 the best handling in the 250 class.
- Speed-Sensitive System 48mm Kayaba fork tubes move the transfer
control valves (TCV) above the fork springs, so that damping force is controlled by piston
speed instead of position. Along with a bigger base valve hole, the result is a smooth
ride and super-precise handling.
- Removable aluminum rear subframe constructed of square-section
tubing for reduced weight.
- Rear, fully adjustable Kayaba shock features a super-light titanium
shock spring and reduced-friction Kashima coating of internals. 12.4 inches of travel,
separate adjusters for high- and low-speed compression damping, and a full lock oil
rebound system for increased comfort all add up to fantastic rear wheel control and a
sweet ride.
- Lightweight front and rear calipers with aluminum pistons and
anti-bubble front master cylinder, 250mm fully floating front and 245mm rear discs,
deliver strong stopping power with progressive feel.
- Lightweight 21-inch front and 19-inch rear Excel rims provide
exceptional durability and help reduce unsprung weight for optimal suspension performance
and handling.
- Tapered rear wheel spacers ease sliding the rear wheel into place
for quicker tire changes.
- Premium Dunlop knobbies offer race-spec traction and wear.
|
- Wide, cleated, folding titanium footpegs are lightweight and provide
excellent comfort, grip and ground clearance.
- Special-design gripper type seat and fuel tank,
forward-canted steering crown and low handlebar provide excellent movement and more
comfortable ergonomics for riders.
- Wide-diameter fuel tank cap ensures easier usage, while larger tank
opening means faster, hassle-free refueling.
- A light and strong ProTaper aluminum handlebar in adjustable mounts
means comfort and control.
- Use of light, box-head bolts throughout the chassis eases
maintenance while reducing weight and increasing performance.
- Repackable exhaust silencer.
- Durable, comfortable handlebar grips.
