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 & 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.
