Bearing wear is minimal thanks to the RF85 treatment. We were pleasantly surprised at how little wear the bearings actually experienced. We'd heard of other racers running up to 6,000 laps on an RF85-treated rearend, but being the cynical types, we always want to see for ourselves firsthand. Well, if the lack of significant bearing wear didn't convince us perhaps the ring-and-pinion's condition would. In this shot the ring-and-pinion look almost new.
