Can anyone tell me which Yamaha models also use the same front mudguard/fender as the TR1?  I know XJ550/650 is the same but are there any other models that will fit? I tried XJ550 maxim but it does not fit.

Hi Nanno, I am not sure it will fit. It looks like the Maxim mudguard but it is not easy to to compare on photos.

I found this website that may help anyone else looking for comparison http://www.cyclepartsnation.com/oemparts/partsearch/yamaha

it shows which motorcycles a part was used, but maybe if the part number is slightly different then there still could be more options

I dont know it exactly but i believe the XJ650 mudguard will fit. The one from the SR500 is a little bit narrower, but i think you can bend it a little bit or put some whashers in. Kedo has also a very nice mudguard for the sr500: http://kedo.de/produkte/22379.html
