I used my 749s for my race licensing while it was completely street legal and I've got to say that even though I was going easy with it I was always thinking of what would happen when it hit the ground rather than how I was going to get through the corner, which was a bit distracting. Once I got it all race prepped it was a lot easier to ride, and it did dump twice, but I was never really scared about hurting anything apart from high siding. With that out of the way, it's absolutely a blast to have on the track and now I want back every time I get on the bike.
I'm not sure about long through the frame sliders for the track but underbody sliders with track bodywork are a must and make sure to get axle sliders as well, I scraped up my swingarm on one side in Reno and while it's still fully operational....it's still scraped up and there's a possibility of damaging the nut which is a pain in the ass to get of as it is. Also, I'm sure you've thought of this already, but if you've got any aftermarket controls or rearsets or anything make sure they come off, I went as far as taking off the exhaust CF shield on the track to help keep that a little safer. I dind't mind the hot seat as I was never on it anyway.
The SV sounds awesome though and I'd love to take that around. Make sure you get us some pics of it goung around when you get it finished.
