The demand for performance-based parts is growing, and these M8 engines are creating more power daily. All that power requires a quality base that the stock cases can't provide. This new version of the MK-Series Crankcases are ready for even more than the originals. These cases are designed to accept cylinders up to 4 1/2", which is massive! Like the originals, these cases scrape more oil than stock and offer more reliability, all without frame modifications.

Redesigned, with 4.695" spigot bore to accept larger bore cylinders
