UPDATE
I did a trackday at Cadwell on the S3 yesterday and I have to say its not an ideal track weapon. While the engine was well up to the job and the suspension and brakes coped well, the ground clearance was a major issue. Footpegs are too low and/or too far forward to be out of the way and I found it difficult to get my knee out further than my toes. If you took this bike to the track and your mate was on a Tuono of similar vintage (as I was last year) you would not keep up. Rearsets might sort it out though...
