ar icipating Dealers These The 1993 Kawasaki KX250 adopts the weightreduction techniques of the KX125, making the frame lighter ye~ equally rigid for improved handling. Engine and carburetion changes enhance power across the rev range. Among the most notable changes, the KX250 adopts the gUillotinetype KIPS valve, providing more accurate port control and better performance all around. Engine compression ratios are slightly reduced, while a combustion chamber redesign aids detonation control. Reduced flywheel effect allows quicker acceleration. If you look carefully, you'll notice a narrower front fender on the 1993 Kawasaki KX500-E5, an aid to weight reduction. The KX500 gets a semi-floating front disc brake along with new graphics. For the most part, though, it's a proven performer needing few changes. The powerful liquid-cooled 499cc two-stroke engine is equipped with the Kawasaki Integrated Powervalve System (KIPS) and capacitor discharge ignition with electronic timing advance. A semi-double cradle, high-tensile steel frame provides strength and agility. The KDX250-D3 is built around a tubular steel perimeter fra"Tle, providing superior torsional rigidity and improved mass centralization for a lower center of gravity. UNI-TRAK ® rear suspension provides high compliance on small bumps and increasingly stiffer resistance to larger impacts to avoid bottoming. Hollow front and rear axles lessen unsprung weight, and the aluminum rims have straight-pull spokes. The 249cc two-stroke single cylinder engine is derived from the KX250 motor, with reduced compression ratio for a wider powerband. The KDX250's exhaust system includes an aluminum silencer and U.S.F.S. approved spark arrestor. MA PHILLIPSTON LEDGEWOOD Cycle Design Ledgewood I
