I got a bit fed up with the high speed weavy/wobbly on the B6, so I decided to replace the decidedly squared off rear with the same tyre. It lasted 9,800 miles which I don't think is bad for a 66 quid tyre. The front still looks fine, looks like it will do another 10K. Since I'm feeling skint atm I've bought a pair of Supermax sports for the 675 - 130 quid the pair. I don't ride it on the bleeding edge so I'm sure they'll be fine for me. ps <rant> When did the bloody road tax go up another tenner to 70 quid? Gits. </rant>
