Performance

Kawasaki KX 250S

The KLX250S’s straight-line stability is enhanced by a rigid square-section main frame, yet its short wheelbase gives it outstanding turning aptitude. Complementing the chassis is a lightweight aluminum swingarm employing a highly rigid D-shaped cross section. KX racing-type chain adjusters allow for precise chain adjustments.

The KLX250S’s custom spring and damping settings, with slightly less wheel travel than a dedicated off-road machine, give a more planted feel in corners and make it easier for riders to reach the ground. The 43mm inverted cartridge-style front fork features 16-way adjustable compression damping and 10.0-inches of travel. The Uni-Trak linkage-type rear suspension has 16-way adjustable compression and rebound damping, providing 9.1-inches of wheel travel. Strong, 4mm-thick spokes in the 21-inch front and 18-inch rear wheels provide excellent rigidity for enhanced off-road durability. The KLX250S also stops hard, thanks to twin-piston calipers squeezing a 250mm semi-floating petal-shaped disc up front and a 240mm petal-shaped disc at the rear.

Aggressively styled bodywork finishes off this powerful and rugged package, and a custom seat filled with firm urethane and a carefully chosen handlebar pull it all together for long, comfortable days on the road and off it.

Riders seeking enduro handling and modern engine performance in a dual-purpose motorcycle designed for effortless street riding will find it at their local Kawasaki dealership. The KLX250S offers serious capabilities in a fun, easy-to-ride package, regardless of where the adventure takes it.
