Wiseco Racer Elite Piston Kit for Yamaha YZ450F 2018 - 2019.

The Wiseco Racer Elite piston kit is the manufacturer's flagship product, designed and built without compromise for riders who put engine performance and reliability above all else. The asymmetrical piston skirt gives the piston the exact properties it needs on both the exhaust and intake sides throughout the various stages of combustion, resulting in a lightweight finished product that delivers up to a 2.9 horsepower gain just by swapping the piston. Piston durability has been improved with features such as reinforcements around the wrist pin and upgraded ring properties. The bevelled piston ring seals the piston more effectively, while a precision-machined ring groove allows exactly the right amount of lubrication into the cylinder. The Racer Elite piston also features an ArmorGlide coating that maintains the piston's properties throughout its entire service life, reduces friction and minimises the effects of temperature fluctuation.
