Attention! This purchase is for a CN clearance! Should you require C3 clearance, we stock them under PN# 70-1591 c3
The absolute best quality UK made by R.H.P. Triumph main bearing, PN# 70-1591. For the record C2 is tighter than CN (clearance normal) which is in turn tighter than C3. These were originally fitted to Triumph triples and we’ve been told they also were fitted to 750 twins to cure bottom end “rumble” that occurred with C3 clearance. Always check the clearance specs for your make and model to prevent damage!
PN# 70-1591 was used as both right and left main bearings, but not necessarily both at the same time depending which year/model engine you have.
Please note: Due the nature of the product, we unfortunately do not accept returns on bearings, service tools or electrical components. Please be confident about your purchase before ordering. If you have questions, please contact us.
