Racing Choice Pistons are 1 ring, 2-Stroke or 2 ring, 4-Stroke with reduced weight and friction as well as increased power and throttle response. Note that service intervals may be increased over conventional Wiseco Pistons. 2-Stroke Pro-Lite Pistons feature lightweight forging for instant throttle response and maximum torque. Computer engineered piston skirt profiles provide minimal cylinder wall friction. Anti-detonation grooves and new ring land diameter eliminates ring blow-by while maximizing engine performance. Piston kit includes pistons, rings, wrist pins and circlips. Note that oversize requires cylinder sleeving and top end bearing is not included in kits. 4-Stroke Pistons feature dedicated forging for lightweight and superior strength. Race-ready dome design provides improved combustion flow and armor glide skirt coating provides reduced friction (racing applications only). Piston kit includes piston, rings, wrist pin and circlips. Note that oversize requires cylinder sleeving.
