Cylinder head UMA Yzfr 125, 25/22

The UMA-Racing Superhead is a high performance cylinder head specifically designed to maximize the power and torque of your engine. With an intake valve diameter of 25mm and an exhaust valve diameter of 22mm, the Superhead provides optimal flow for improved cylinder filling and more efficient exhaust removal. The combustion chamber is apple-shaped, which provides an increased sealing ratio and thus a significant increase in performance.

Among other things, this ensures optimized heat dissipation so that the "hotspots" remain cool in relation. The centered spark plug ensures even combustion and thus a much smoother running engine. The cylinder head comes with all the necessary parts ie: camshaft, cylinder head, intake manifold, etc. and can be mounted plug & play without further ado.
