Cylinder Head Services

The cylinder head is the key to getting the most power out of any engine. Motorrad One (“M1”) is at the forefront of cylinder head development for BMW Motorcycles. We use our Superflow Flow Bench with Performance Trends analytic software, a Newen CNC valve seat cutter, Haas VF4 4-Axis CNC machine, and our Dynojet to fully develop our STAGE cylinder heads. We also offer several custom features like +1mm over-sized valves, beryllium seats, M1 race springs and M1 titanium retainers. We also offer complete custom heads for unique applications. Our Pro RACE Heads are completely ported and have CNC valve jobs. Just add one of our Stage 5 performance camshaft kits for maximum power.
