Quality cylinder from Athena that offers a 47.6mm bore and a performance equal to Stage6's Sport Pro MkI, which proves that there is bang for the buck with this kit from Athena.
Despite the name "Sport", we describe it as being in the 'Racing' class as it can perform more than e.g. Malossi MHR Replica 70cc cylinder kit. ATTENTION This kit comes with a ø12mm cross stitch.
A spark plug with a short thread must be used for this cylinder. Delivered incl. gaskets and other accessories for assembly. The cylinder must be squished to 0.90mm according to the accompanying manual.
Note: The cylinder cannot be fitted to models from 2003->, unless the restriction in the engine block is removed. If the cylinder is fitted, it is no longer possible to use the original or other Euro2 exhausts. Both parts apply to models from 2003->. This does NOT apply to PGO engines.
