i run a michelin pilot for the rear 150/70/17 and a bridgestone bt014 for the front 110/70/17.

no problems with chain alignment as there is still about half inch of space between chain and outside most edge or tire.

i had tried to run a 120 on the front but the rim being narrow caused the tire to crown excessively. this led to great turn-in as the bike would drop into turns but horrible when it came to transition from side to side, could not get the bike back up and over again quickly enough as i had to muscle it.

I just purchased 140 70 17 and 110 80 17 on the front. The dealer that sold me the tires said that any wider on the rear would cause the bike to handle bad and cause excessive wear as well as pinch the tire (whatever that means). I see some of you running 150 and talking about 160(which would be awsome) . None of you have had any probs with this.

At least I will know next time.
