Casa Performance Radiale finned cylinder head (for optimum cooling) for SS225 engines, with offset (i.e. standard position) 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 SS225 kit and provides mental cooling and therefore your scooter runs MUCH better. These are 'plug n' play' and are a straight swop for the standard red coloured CNC'd heads supplied as standard with the kits.
Spark plug alignment is as per standard and no modifications are required for the fitment.
