Puya is right. I have a 03 R1 fender on my 02 R1 forks, but the 01 is different. If you sweet talk your parts man , you may be able to pick up a new fender for about 89.00. Stay off e-bay though, thery're generally trashed and people want too much for them. FYI, the gap btwn the fender and 18" tire and rim is pretty tight, it'll fit but leaves little room for gravel to get through. Being a FL resident I only have to worry about sand so this is not an issue. Up in Deals Gap, there was a bit of gravel around and I was scratching my head trying to figure out what all the noise was coming out from under the tank.[xx(] Turns out it was the small rocks shooting out from the fender.[:0]
