I've been to Mallory Park, Rockingham, Brands (short), Snet, Cadwell and Goodwood. The bike favours shorter, nadgy, circuits where the R1s and Blades can't simply grunt past you on the longer straights. It definitely suffered at Snet. At Goodwood, don't ask, never saw the feckers after the second straight. Cadwell was reasonably fine (the circuit's so nice I would pay to do it on a pushbike) and Mallory the best, at least for the 1200. You can do a lot of catching up on the bends, breaking later as the entry speed is so much lower and in some places keep the throttle pinged open when the 150 bhp boyoes are shutting off a bit. Plus it's a laugh, but not as funny as the Pan Euro we encountered, with panniers and radio on, smoking lots of road rockets in the advanced group at Mallory

it reduced some to muttering about the mobile chicane. I did all mine on the Dunlop on /off road hybrid OE tyre (can't remember the name) without any prob's. May try some Bridgestone BT 0 whatevers.
