Hey dabs, I may be able to help you out here. I dont know if this is good practice or not but if it is you could probably have a free trial of b20's. When I get my fazer back from GW's AGAIN I will be swapping my part worn b20's for at least B14 if not stickier. I have lost both ends on these tyres. I am not blaming the tyres for my off's but I beleive the combination of my suspension and the power of the bike and the way I was riding made them let go. So thay have a good few miles left in them and they are not flatspotted at all. You can pull up to any biker meet with these on mate, as there is no chicken strips on them, they have been scrubbed to the rim.

Anyway I digress, I probably wont get the bike back until Jan anyway so if its deemed by the experts on here to be safe to use part worn on another bike then you can have them to see if you like them, because I will never ride with them in anger again. My rear is a 180 section, is that the same as yor TT?

Keep in touch and I'll let you know when they are available, either that or they will be in the bin

Cheers

Steev
