Oh great another tire thread....anyways:
I have some stock sizes from my 01-1150gs. 150/70-17 rears work great on the rear of these bikes. Michelin Mutants are pretty expensive, but they are tough to break down. So are the more street oriented 80/20 metzleer tourance in same size.
I love the handling of the Michelin pilot series. It literally feels like riding on a rail, even on heavy touring bikes, the corners feel as if they dont exist.
Offroad tires on Pavement: You make more noise as you ride, and pending the conditions your up against, there is a possibility the closer to 50/50 tires you get they may lose grip on certain road surfaces..
I road my 1150gs allot. And there were times when canyon carving on asphalt.. Id lose the rear tires cornering (on 50/50 or 70/30 treads). That I believe was to me being too aggressive on the corners, or throttle. or both...
the shinko e705 is a nice tire, hopefully you dont blow them off the rim...that happened to me, so I am not really likely to run them anymore. at all...Your Mileage May Vary...
So we have to remember that not all tires are the same size even when they "are".....But everyone has assholes as much as they have opinions., these are just mine.
