Negative Ghostrider, the fender is full.
Classic R3's run a 240 fat tire in back whilst we run a 180. I don't believe that there is enought room to fit the bigger tire.
And there are at least 2 reasons off the top of my head why you wouldn't want to.
1. The narrower tire on the touring gives us a lot more ground clearance for the twisties compared to the classic. Cornering is a breeze (comparatively) on the touring.
2. Our rear tire is one hell of a lot cheaper than the classic 240. (darkside not withstanding)
While I think that the fat tire on the back looks cool, in my opinion it is a liability when it comes to carving up the twisties (not to mention your checkbook).
