+1 regarding the radiator. The S2R is raw Monster. The added benny is the bulletproof 2V motor.Chops said:S2R - think old school:
S4R - latest and greatest:
radiator (keep it filled with Bourbon for max cooling effieciency)
Personally I'm all over the S2R. It's just what the monster is supposed to be. That radiator looks silly sticking out beyond the limits of the bike (there I said it!). You want all that extra, get a superbike.
