No radials available in the stock front size of 110/90-18. I have a 110/80-18 on mine. It is about 9/10" shorter than stock. The 120/70-18 is about 1.2" shorter than stock. I will not get the 120 due to the rim size. I did buy an 85 front rim that I was going to sent to Kosman to widen but haven't got the funds yet. Then will be able to mount the 120 tire.
How is that one working out for you? The 110/80-18?
