UNI 200c Crankcase - Without Engine Mounts

This Crankcase is a direct replacement for the no longer produced SIL GP200 crankcase. New tooling, an excellent foundry and the same process (pressure die casting) as used to manufacture the original Innocenti/SIL crankcases ensures a high quality product. There have also been a number of small upgrades; The base gasket surface has been enlarged to allow matching of transfers without compromising on the thickness of the gasket surface, also the transfer symmetry has been optimised. The outer diameter of the primary compression area has been made thicker to facilitate machining to suit longer stroke crankshafts. The engine mount positions have been strengthened. The rear brake shoe pivot and cam positions have been corrected to improve braking performance. Along side a number of smaller improvements.
