CP Pistons CPK piston kits come complete with a piston, wrist pin, locks, rings, and gasket. The anti-detonation grooves, also known as contact reduction grooves, protect the top ring by disrupting detonation waves. These grooves also limit the piston/cylinder contact during high temperatures and rpm. The featured accumulator groove is a V-shape machined into the second ring to collect excess blowby between the top and second rings. The accumulator groove also collects residual gasses during combustion and alleviates top ring flutter, while increasing ring seal. Other features, such as double pin oilers, in conjunction with their dual fed reservoir, add twice the amount of oil from the cylinder wall to the wrist pin. CP wrist pins have fine grooves that are intrinsically engraved into the product surface at the time of machining. These grooves are transformed into micro-dimple indentations to act as oil reservoirs, and the oil that would normally drain away through the grooves on an untreated product still remains in the dimples. X-forgings minimize friction and reduce weight without compromising strength. CPK piston kits go above and beyond in both quality and dependability.

These CP Pistons Project X piston kits have expanded from custom racing applications to off-the-shelf, fully boxed-style pistons that fit a variety of street bikes and powersports applications. These kits include the piston, pin, locks, rings, and gasket. CP's fully boxed forgings are designed to minimize friction and reduce weight without compromising piston strength. CP Pistons Project X piston kits offer near-unbeatable strength by incorporating braces and ribs to adjust the weight balance between high and low areas. All Project X pistons come standard with a skirt coating that reduces friction, which in turn reduces heat. CP pistons Project X piston kits offer external bracing to minimize piston deformation and maintain maximum ring support, while delivering more power. All CP Project X wrist pins have Diamond-Like Coating (DLC) and are manufactured from steel with a metal-free carbon coating that is harder than steel, ensuring durability unsurpassed by any other pin on the market today!
