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.
Features And Benefits:
Stock deck height
Machined, close-fitting oil scraper (stock is as cast)
Large volume sump
Redesigned, with a 4.695” spigot bore to accept larger bore cylinders
