EN125 57MM CYLINDER

EN125 57MM CYLINDER

The EN125 57mm Cylinder is an aftermarket or performance replacement part designed for the Suzuki EN125 motorcycle engine. With a 57mm bore diameter (larger than the stock 56.5mm bore), this cylinder increases the engine’s displacement slightly, leading to improved performance and throttle response. It's built using high-quality aluminum alloy for durability and efficient heat dissipation, with a cast iron or plated liner to reduce friction and wear during high-speed operation. This cylinder is widely used in engine rebuilds and performance upgrades for EN125 motorcycles. "
