KTMs aren't about doing burnouts and wheelies. They'll wheelie no problem . My 990 is just under 400 lbs with the fuel light on and has, I'm guessing 10% more torque than a modded 919, so yeah, it'll wheelie. Burnouts are just plain stupid.
BSAs? That's soooo far off the subject, I'll never fgure that post out.
It's a KTM thing. You wouldn't understand.
BTW the dealer in Terre Haute has a 690 for $9K.
