By a strike of luck, Kev has obtained a few more sets of these fork spacers as his previous supplier had temporarily stopped production, I cannot reccomend these mods enough but if you don't believe me just read the 100% positive comments from other forum members who have fitted them in these threads:

If you want a set of these mods please send a pm to Kev a.s.a.p. as these might be the last set we can get hold of for a long time.
