I've taken my sf to the track once. It was fun but honestly, it does not compare to the fun I have on my race bike. I think part of it is because I'd hate to dump a $15k bike where as on my race bike, i know it's going down some day and accept that. The SF does handle pretty well on the track but that's after I tweeked some of the settings. Foot pegs defintely touch down a bit early. Also the right heal guard really gets in the way of body positioning. Lastly, for some reason, my bars vibrates extremely. Half way through the sessions, my hand was numb and I had no idea what it was doing. I'd come up to a turn and hope it was hitting the brakes. Only way I could tell was that I was actually braking was because the bike was slowing down. Will need to look into why that is. I'm running some Fatbars.
