Product Overview

CP-Carrillo - MX1026 - 450cc - Yamaha - YFZ450 - Piston and Ring Kits

CP-Carrillo offers two kinds of 4 stroke : standard “M” kits and “MX” kits.  The main difference between these parts is that the MX kits are a fully boxed style part with skirt coating.  These pistons took about 2 years to develop – it actually started with Ricky Carmichael.  These MX kits will come standard with DLC.

CP Piston M piston kits are available for your powersports applications. These kits include the piston, pin, locks, and rings. CP Pistons use X-forgings to minimize friction and weight without compromising strength. Double pin oilers add twice the amount of oil from the cylinder wall to the wrist pin. Radiused domes are used to maximize quench, while eliminating possible hot spots that promote detonation. CP Piston M piston kits have a V-shaped groove machined into the second ring to collect excess blowby between the top and second rings. This groove is known as the accumulator groove.
