I can only find a extension for the X can anyone tell me if it will fit on the R , as gritters are out and want to try stopping salt spray (as it not only icy when they spreading seems to always rain the next day) read a few about making them e.t.c. I have one on my Honda grom and that works great but don't want to purchase and doesn't fit , know I could make one too but they never look as good as properly moulded one hope someone can help!
