I am surprised I have seen it done before on a 1100 but they machined part of the shock mount off so that the tire didn't rub. The 1150 has the different bottom mount so perhaps its not as easy. I think either the R100R and/or the 1200 crusier has an 18" front rim with crossed spokes so if you found one of these wheel you could try lacing up one yourself.
But from what I have been reading on here the 18" rear wheel doesn't make that much difference for general use other than tire choice.
