2006 Kawasaki KX250

Stuff a stick of dynamite into a motocrosser and light the fuse. What do you get? The KX™250. Completely overhauled last year for better performance, sharper handling and improved ergonomics, the KX250 is the most potent, fastest and best-handling two-stroke we’ve ever built. Period. Its compact, lightweight engine features Kawasaki’s exclusive KIPS® power valve system that broadens the powerband for more muscle everywhere you need it, allowing astonishing drive out of corners and maximum thrust on the top end. Just ask winners like Darcy Lange and James Stewart. With two consecutive Arenacross championships and multiple 250cc Supercross wins under its belt, the KX250 delivers the goods. And for 2006, we’ve added refinements to the engine’s reed-valve assembly, fine-tuned the front and rear suspension, upgraded the brakes with trick petal-type rotors that enhance braking performance and save weight, plus a host of other improvements. The new KX250 from Kawasaki. If you like racing, we’ve got the bike.

Several motocross magazines hailed the 2005 Kawasaki KX™250 as one of the best all-around two-stroke motocross bikes due to its sheer power, ideal handling and superb brakes. As one magazine said, “The 2005 KX250 is phenomenal!”

And while it’s sometimes difficult to improve on a winner, Kawasaki has succeeded in making the KX250 even better for 2006 by fine tuning the engine, suspension and brakes.

To make this 250 Supercross race winner even quieter, the 249cc, liquid-cooled, two-stroke engine features a new piston profile, while a longer, wider silencer ensures the KX250 meets modern noise emission standards. Plus, the silencer’s all-new, long-fiber packing is more durable and requires less maintenance. And to keep the KX250 at the best-possible temperature, a new water pump impeller increases coolant circulation.

Changes to the KX250’s chassis include a strong, lightweight Renthal aluminum handlebar, and the rear shock now features dual compression adjustability so riders have more tuning options for both low-speed and high-speed compression damping. Up front, the Kayaba AOS fork has a new, one-piece sleeve to improve suspension action at full compression.

For 2006, the KX250 has even stronger stopping power. The new petal-style disc brakes are not only lighter, but their shape helps to clean the brake pads for more efficient braking performance.

The KX250 also features a new look for 2006, with aggressive new graphics and a new, two-tone seat.

Kawasaki offers optional parts for the KX250, including carburetor tuning parts, ignition rotors, a larger countershaft sprocket, aluminum and steel rear sprockets, solid brake discs for wet racing conditions and a 20-inch front wheel.

Those who race their KX250 at designated events are eligible to receive support from Team Green™, Kawasaki’s amateur racing support program. Each year, Team Green provides regional support vehicles and highly trained technicians at more than 100 events, offering technical information and assistance to those who race Kawasaki products. Kawasaki also offers a comprehensive contingency program for amateur and professional riders who place well at designated events.
