Anyone? I know RockJockey has both bikes, would love to find out. I just bought a 650L and want to put my black Excels over on the 650 and get rid of my 02 XR400. The XR will be parted due to all the goodies. I wish the gas tanks were interchangable so I could put my 4 gallon Clarke on the 650. Also, If the hubs don't interchange, anyone know if the rims and spokes will? I can always relace, that would give me an excuse to do some good street oriented tires anyway. Thanks in advance.
