I have 2 flat tracks and a .6 mile TT course, and I bring newbies out to ride 100-150cc bikes on the TT and my flat tracking TTR 125's with chinese street tires on 17" rims on the flat track. Wet that puppy down in advance, then get out there and learn riding "the Roberts way!" Best training going, IMO......falling down a LOT. Helped my road racing skills significantly.....because you get used to the bike moving around underneath you. Then when it happens on pavement at 90 mph in a turn, you aren't tensing up......which is about the worst thing you can do, short of chopping the throttle or grabbin the brakes.
