Wiseco Performance Products, Mentor, Ohio— Wiseco is introducing 2 new pistons for popular KTM bikes. The first is a hi-compression piston kit that fits the KTM 450EXC, MXC, and XC-W 2003-07. The 13.5:1 compression piston is skirt coated to reduce friction and allow for quieter operation, along with maximum torque and throttle response. Pistons are sold complete with dedicated rings, piston pin, and circlips. A complete top end rebuild kit is soon to come that will include a complete Wiseco top end gasket kit.
