Description: Zongshen 250cc engine 72.5mm Big Bore Kit is a product designed to enhance the performance of motorcycles and scooters from various brands including Hawk, XPRO, TaoTao, Apollo, and SSR. The kit includes a larger piston and cylinder to increase the engine displacement, resulting in improved power and torque. This product is specifically designed for Zongshen or similar CG250 brand engines and is compatible with various models. You can expect a substantial gain in bottom end torque, and around 5-10mph top end (this varies greatly depending on rider weight and specifically with what other mods you have). If you weigh 500 pounds and are not getting a 20mph gain in top speed, it's not because of the kit! ** This is a complete top end Big Bore rebuild kit, with 72.5mm piston, piston rings, pin clips (Circlips), 16mm wrist pin, valve stem oil seals, exhaust and head gaskets.** ***Some newer model CG250 engines might have a smaller engine case diameter than previous models, requiring minimal machine work. i.e. turning the cylinder sleeve down to 75mm or opening/cleaning up the engine case diameter. However, the bottom end gain is well worth it, especially if you are looking for big torque gain.***
