Description

Top quality RHP left (primary) side main bearing as fitted to Triumph 650 1966-72 & 750 1973-76 unit twins & 1966-1972 BSA A50 & A65 unit twins in CN (clearance normal) clearance. CN bearings are tighter than C3 and not as tight as C2. These were standard in BSA unit applications as well as many Triumph 750s. Triumph 650 twins generally were fitted with CN clearance, and to add to the confusion late T140s were fitted with C2 clearance bearings.

Always check the clearance specs for your make and model to prevent damage! Bottom line is that after 40+ years of wear and tear many engines now need different clearance bearings than they originally came with!
