Cylinder cover from Polini, suitable for the 47 mm Evolution cylinder kit with four stud bolts on your Piaggio Ciao, Si, Bravo and Boxer moped / moped.
The large sealing surface ensures uncompromising sealing, while the optimized combustion chamber enables ideal combustion. The additional cooling fins on the sides help to dissipate the heat generated more efficiently. As a result, this racing cylinder head protects your tuning cylinder from overheating and piston jamming.
There is a mounting option for a 3D nut with M6, for example to fix the circuit exhaust to the head.
Notes:
A cylinder plug with long thread is required.
The original deco valve can still be used.
You can find a suitable spark plug, the complete racing kit and other add-on parts in the accessories.
