The Wiseco Pro-Lite Piston Kit is a high-performance forged piston designed for Yamaha YSR50 models from 1987-1992. Made from high-silicon, low-expansion aluminum, it offers superior strength, reduced weight, and improved heat transfer. The lightweight forging enhances throttle response and maximizes torque, while the computer-engineered piston skirt profile minimizes cylinder wall friction. Anti-detonation grooves and optimized ring land diameter help eliminate blow-by and improve engine performance. The kit includes the piston, rings, wrist pins, and circlips.
