TDR Racing 183cc (63mm) cylinder kit for Yamaha NMAX 125cc scooters.

Aluminium/ ceramic cylinder is supplied ready to install. The light weight aluminium cylinder conducts heat more efficiently than cast iron cylinders, the ceramic coating reduces friction between the piston and cylinder, reducing operating temperatures, increasing cylinder life and improving performance. These cylinders have been tested by professional racing teams in the far east.
