Our local Kart track hosts an outfit that offers supermoto classes, So Cal Supermoto. They supply everything, including a Suzuki 400 SM, for $250 a day. They run sessions with instruction between them; I think the class lasts at least 4 hours. You might check local tracks for similar.
A few months back I got out on that track with our 390 Duke, and the SCS students seemed to be studying lines, rather slowly. That little Indian thing does have another 7 or 8 rwhp. It also has ABS, and I noticed that if I got the rear at all loose under braking, the front brake force was reduced. So the ability to turn ABS completely off on both the Duke and the Strada is a good thing on the track. I'd be tempted to do the same if I were trying to go quickly on a dirt road. After all, how many true dirt bikes have ABS?
The only bike I ever had that I bought pretty much just for the ABS feature was our 2008 Road Glide. The car-type rear brake pedal on our '01 E-glide was impossible to modulate properly, and I got tired of locking up the rear wheel.
