With race season in full swing, Wiseco has brought out its high compression complete top end rebuild kit for the 2009 Kawasaki KX450F. The piston comes packed full of features you expect from Wiseco. The piston is built on a dedicated forging, made right here in our Ohio plant to give you maximum torque and throttle response. Our ArmorGlide™ skirt coating gives improved scuff resistance, reduced friction, and provides quieter operation. Match our high compression piston with our unique 6-spring forged extreme clutch kit and your bike will be ready to race! The 6-spring design improves clutch grip and better distributes the spring load. Wiseco’s extreme clutch kit comes complete with a forged clutch basket, inner hub, and pressure plate, friction plates, steel drive plates, and clutch springs. Wiseco’s ‘One Name. One Solution.®’ is now available to you with the 2009 Kawasaki KX450F. Check out everything we offer for your KX450F on our website at http://www.wiseco.com/.
