I've been and priced them up, £175 fitted for the pair, gonna see if I can get any better prices, there's alot of competition around here for tyre prices. Thanks for the advice, I was at my wit's end. In all honesty, this bike has given me so much grief over the past couple of years that I'm considering moving over to a Z1000, my previous bike was a Yamaha and it had all the same quirks (no fuel gauge for a start).
Sorry, random rant there, gotta find something to keep my mind off of my mundane job!
Thanks guys!
