, bike sold for £531. Taking Maxim's advice i stopped bidding when it started to go over £500. after reading lots of threads on here & looking at aftermarket parts availibilty i've made the decision to spend a bit more cash and wait for a 21 to turn up. So if anyone has a cheapish 21 that they want to sell, preferably in he south east area then let me know. in the mean time the search goes on!
