Increasing the KLXs engine size from 110 to 150ccs brought about a huge increase in power. Unfortunately along with more power comes more heat. At $385 the Moto HP oil cooler kit may not be the cheapest kit on the market but it is a quality product that has been specifically designed for our bike.

The KX85 is powered by a liquid-cooled, two-stroke, single-cylinder 84cc engine that has features, such as an Electrofusion-coated cylinder with a narrow squish band and large volume combustion chamber to enhance top-end power.

Kawasaki engineers reinvented their 250 racer with a new slimmer look, lighter handling, better ergonomics and a host of changes that enhance engine performance and improve durability.

Kawasaki's KLX 140 dirtbike with its 17" front / 14" rear wheels has opened the door for a wider variety of riders in the small displacement off-road arena. More advanced or longer-limbed riders can turn to its sibling, the larger 19" front / 16" rear wheeled KLX140L. Both 140s are designed to be beginner and novice friendly, yet offer a roomy layout and enough performance to suit more-advanced riders.

With its liquid-cooled, high-performance engine, full-race chassis, long-travel suspension and disc brakes, the smallest KX model is a pure racer.

Comprehensively re-designed with a new fuel-injected engine, chassis, bodywork and extensive durability enhancements, the 2009 Kawasaki KX 450F motocrosser is more high-tech than ever.

The days of settling for cramped ergonomics and limited performance aboard simple one-sized machines are over. With its 19" front / 16" rear wheels and advanced rear shock, Kawasaki's KLX 140L dirtbike is the ideal match for more experienced or longer-limbed fans of small displacement off-road machines. Its more elementary sibling; the 17" front / 14" rear KLX140, is an option for novices and smaller riders.

The KLX110 is motivated by a user-friendly 111cc air-cooled, two-valve, four-stroke engine that features a screw-type adjustable throttle limiter. This easily accessible item allows parents to adjust the maximum speed and power output to suit less experienced young riders.

Kawasaki's 2009 KLX 450R may have inherited the lightweight engine and chassis from the multiple championship winning KX 450F motocrosser, but it is much more than a high-strung racer with a headlight and 18-inch rear wheel. Designed for the the off-road world, the KLX450R delivers a wide spread of power with high-traction torque and superior throttle control, combined with the enhanced durability, comfort, and long range that's required in off-road environments.
