think the answer is probably not given they look very different on OEM microfiche yet on German eBay someone selling ront and rear mudguards saying they fit R80g/s and R80gs?
Hi Kav teh subframes are different.
If i remember , i think the mounting holes for the mudguard are in a different place.
so I would say no, not without a bit of messing.
Thanks for the replies gents, there was a nice newish looking one on ebay for a R80GS but think I will give it a miss until a G/S one turns up that will definitely fit.
