After the last discussion on the difficulty of finding the correct size rear tire for our R1100 I was on the lookout for a 17" wheel from a K1200RS or LT. One showed up on a bike from a wrecking yard about 120 miles from here so I went and purchased it. I also remembered that someone indicated that longer bolts were needed, so I also got the bolts along with the wheel. Today I pulled the stock set up and tried to fit the wheel, seems that the 170/60-17 tire on the rim won't clear getting into the cavity short of pulling the muffler or caliper, even with the air let out. But now for the bolt question, the stock bolts on my 1100 are 60mm long and the bolts for the LT are 54mm long, checking what protrudes it seems I have plenty of material to hit the hub on the FD, so am I missing something or is even a longer bolt required?
So far, I have calculated the size that ends up closes to stock is a 150/70-17, it's about 7 revolutions more than stock per mile.
