The new BIG BORE Ø 50, stroke 39,2-39,3 and 44, cylinder kits comes from the technology of the famous Malossi 7 ports cylinders. They are designed for both Minarelli and Piaggio engines.
All pilots, thrilled about the news, wished to test them. The expectations were not disappointed : the power increase and the absolute reliability proved, once again, the high quality of the products and Malossi professionalism.

Technical specifications:
- 7 ports cylinder, H2O, gravity melted in aluminium alloy, cylinder casing coated in cermetal, lapped with diamond tools
- Bore 50
- 1 ring, strengthen and rounded head piston
- KDN5 cast iron piston ring Ø 50 x 0.8

Technical note : the BIG BORE cylinder kits must be used only coupled with Malossi crankshafts.

ATTENTION: to grant the due stiffness to the cylinder kit, the cylinder has an introduction diameter into the crankcase of 56,2 -0,1/-0,2 mm. Therefore, it is necessary to bore the crankcases with a boring bar of 56,7 + 0,0/0,1 mm for a depth of 21 mm.
