Trying to decide between the Pirelli diablo and the Michelin pure sc for my grom. I'm racing mini moto mostly against crf100's. Does anyone have experience with either or both tires? I took the bike out for testing at a trackday last weekend on the stock tires. Felt like I was riding on ice. What made it worse was the pegs constantly dragging and popping the rear tire up in the air. I think I took care of that with rear sets but now I'm looking at tires.
