Several motocross magazines hailed the 2005 Kawasaki KXâ„¢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.
