KX 250
Kawasaki Motors Corp., U.S.A., diligently refines its KX racing motorcycles to a very fine pitch. Starting with simple but powerful designs, Kawasaki studies the lessons learned from the previous year of competition to make the next model faster, better handling, and easier to ride.
The KX250 for 2004 has received a host of refinements resulting in increased engine performance, improved handling and greater rider comfort.
To give the 249cc two-stroke engine excellent top-end without sacrificing hard-hitting low- to mid-range power, the combustion chamber has been reshaped for higher compression, the intake ports have been reshaped, and the new crankcase casting eliminates the boost port at the rear of the cylinder to speed the fuel-air mixture through the transfer ports. Plus, a one-piece aluminum KIPS® valve replaces the earlier two-piece steel valve, the KIPS governor ball guide has been reshaped, and new expansion chamber dimensions all contribute to improved power delivery.
