Long Description
This SR70 47MM water-cooled cylinder kit is a professional big bore performance upgrade part specially designed for Aprilia SR50 and SR70 2-stroke liquid-cooled scooter engines. Different from ordinary air-cooled cylinders, it adopts optimized water circulation cooling structure, which efficiently takes away engine heat during high-speed and long-time operation, avoiding overheating, power attenuation and cylinder burning.
The cylinder is made of high-strength cast iron liner with high hardness and ultra wear resistance, perfectly adapting to modified high-power operation. Precision machined 47mm bore size ensures accurate fit with matched piston, piston rings and full gaskets, maintaining excellent engine compression. This complete kit thoroughly solves common faults such as engine power shortage, oil burning, air leakage and overheating failure caused by aging original cylinders. It is the best choice for daily maintenance and displacement upgrade of SR series scooters.
