High Performance Speed Kit - Max Bore 54mm (100cc)
This Max Bore 54mm (100cc) high performance speed kit offers one of the biggest power upgrades available for Minarelli-type 2-stroke engines used in ATVs and scooters. Machines from Eton, Polaris, Adly, Hyosung, Jog-style platforms, and Vento gain stronger acceleration, more torque, and improved throttle response. It’s an ideal option for restoring a worn engine or moving to a high-output setup that delivers noticeable gains across the entire powerband.
