These rims were originally purchased as a spare set for wet track days. I had the Pirelli Diablo rain tires mounted on the rims but have never used them on the bike. The rims are in great shape - just a couple of very minor scuffs.
I also have a second set of rims (same as above) but with Michelin Pilot Power tires mounted - these rims were used regularly and have a few more scuffs on them. The tires have approximately 4 track days on them - not much life left in them (if any).
