cylinder kit Airsal sport 125cc 54mm for Yamaha YBR 125, XT 125R, XT 125X AS35952

Powerful aluminum cylinder kit from Airsal with 125cc engine capacity and hard-coated cylinder bore. Compared to cylinders made of from cast iron, the aluminum cylinder has a significantly better heat dissipation. Therefore, the cylinders are less susceptible to wear or piston seizure due to thermal issues. The Airsal Sport delivers power low down and a good torque curve. The compression is designed for use with the original cylinder head. When installing, the carburettor must be re-tuned or better replaced with a larger sports carburettor. Required parts for install are pictured and included.
