Casa Performance Radiale finned cylinder head (for optimum cooling) for SS250 engines, with a CENTRAL sparkplug hole. The idea for this new head has been concieved, designed, tested and manufactured by us here at RLC for the Casa Performance range. This DRASTICALLY reduces the running temperature of the SS kit and provides mental cooling and therefore your scooter runs MUCH better.
As the position of the spark plug hole is CENTRAL on this head, you will be required to make a corresponding hole in your cylinder head cowling.
To achieve 250cc you will need a CasaCase engine casing X210 with a 64mm stroke crankshaft.
