Cylinder head -MRP Polini 152cc (62.0mm)- Vespa T5 125cc
Part no.:
MRP372
Description
Tuning cylinder head completely milled from a solid piece of aluminium for Polini 152 cylinder kit.
This head covers all desired engines, from the plugged 152 to the full range with large carburettor, diaphragm and resonance exhaust. Heavily enlarged cooling surface due to cooling fins on both sides and full-surface airflow.
Modern combustion chamber design with optimum power output and extremely low susceptibility to ringing. Completely milled from the solid. No casting blowholes or breaking heads (no special case!). Manufactured for spark plugs with long thread (we recommend Bosch W3CC).
sealing to cylinder with supplied O-ring. No more problems with leaking head and side air.
Lovingly produced in small series. Of course completely made in Germany.
