firstly that is the bargain of the century an 04 in very nice condition just sold in ebay for £3100 dont know about the first tube but just make your own loop tube up hope you enjoy it mate
they fit so the bearings are the same all years if you havent checked your bearings like i didnt do it quick clean em and re grease them much easier than replacing them it was a bit of a pain to say the least fork seals next
hi i have a 97 315 and the headstock bearings have gone i have just ordered some of ebay but i have since noticed they are for 2000 - 2004 do you know if they will fit mine
