Has anyone used the 80-100-21 Pirelli MT-16 on the front of a 990? I need an aggressive tire for just 2 days coming up this weekend at the Desert 100 DS run. Am I going to have any problems with this tire? It's a new tire I've had for a couple of years on a wheel I've never used. It's DOT but I was wondering about the weight of the 990.....any issues?
