Cylinder kit UMA Yzfr 125, 63mm

The UMA Racing products are specially imported from Malaysia to provide the best possible performance.

The UMA cylinder kit was developed for racing. With 63mm bore and just under 183cc displacement, you can get some really impressive performance from the Yzfr 125. The cylinder can be mounted with the original 19.5/17 cylinder head as well as with a racing 23/20 cylinder head. The outer ceramic coating is for improved thermal and thus increased wear resistance.

The performance from the cylinder is reliable and constant. The power can be trimmed up to 20 hp with the right configuration, which increases by one third compared to the conventional power. All necessary parts (pistons, piston sealing rings, cylinder gasket, cylinder, etc.) are included, which makes it much more convenient to install the cylinder.
