Wiseco Racer Elite Piston Kit for Yamaha YZ250F

The Wiseco Racer Elite piston kit is the manufacturer's flagship product, designed and built without compromise for riders to whom engine performance and reliability are absolutely paramount. The asymmetrical piston skirt gives the piston the exact characteristics it needs on both the exhaust and intake sides during the different phases of combustion, resulting in a lightweight final product that delivers a power increase of up to 2.9 horsepower simply by swapping the piston. Piston durability, on the other hand, has been enhanced with features such as reinforcements around the piston pin as well as new piston ring properties. The bevelled piston ring seals the piston more effectively, and the precision-machined piston ring groove allows just the right amount of lubrication into the cylinder. The Racer Elite piston also features an ArmorGlide coating, which preserves the piston's characteristics throughout its entire service life, reduces friction and minimises the effects of temperature fluctuation.
