If you’re building for power and responsiveness, stepping up compression is one of the most noticeable changes you can make. This Kraftwerks 12.5:1 Piston Kit is designed for high-performance KRX builds that demand stronger combustion efficiency and sharper throttle response.
Built in collaboration with CP Racing, these pistons use forged 2618 aluminum to handle heat and stress without compromise. Compared to lower compression setups, this kit is aimed at riders who want maximum performance from a naturally aspirated build or a properly tuned setup that can take advantage of higher compression.
