You're more than welcome to give the old girl a whirl at Llandow next year, mate. You'll find that they are very similar to the NSR in terms of ergonomics etc, so I'd think you'd feel quite at home straight off the bat. Hopefully have a bit more at the top end than last year too, so hopefully it won't be too disappointing an experience for you power-wise. I'm hoping to have the 21 sorted by then too, as I'd like to take them out back to back. It'd be interesting to see how they compare on the track. I'm pretty sure my RS250 (Aprilia) is quicker on the track than the 3XV, but on the road there's no contest about which is the nicer (and quicker) bike to ride.
Cheers
