Do not skimp on your expensive Norton Commando engine rebuild! This FAG brand 'Superblend' main bearing features precision machining to CN clearance tolerances and a brass cage for longevity. Can be fitted to both the timing and drive side of your crankshaft, sold individually.
A note on bearing clearances: We offer these bearings in both CN (tighter) and C3 (looser) clearance fits. As there is no "correct" or "one size fits all" solution as to which main bearings you should fit, we highly recommend doing as much research on the subject prior to purchase.
