I would rather have the 690 as well. But then I actually have one. It's spent most of the 27K miles I've racked up on it with the 17" wheels. When I first read your post about track riding I thought you meant a MX track which is the reason I mentioned the smaller bikes. The 690 would great for a road race track. I had mine out at Eagles Canyon Raceway before which isn't a great motard track and it was still a lot of fun. My track bike at the time SXV 550 and the 690 actually handled a little bit better then the Ape, it just couldn't touch it on HP though.
