Hey Dutchy. I have Angels on my RC-51, like them a lot. I don't have a spare set of tires (or wheels!) for track days, so they are a very good compromise IMHO. Not as sticky as a track tire, but a much wider temperature range for street use.
BTW, last night I watched race 1 of the opening round of the 2000 WSBK season, Kyalami. First RC-51 race, fantastic finish, Edwards vs. Haga. Fogerty, Chili, Corser, Crafar on the other RC, Bostrom, and even the GoShow (DNF). Thought of your bike in Castrol colors, fun stuff!
