nice weeleez !!!
Trust me; they are not hard to pull!
Easier to pull a wheelie on a 600 than on a 125.
Good fun though!!
I've seen people fall and mishaps when they tried wheelying, but its not a hard thing, push back and accelerate the torque, you'll be up there.
Just got to keep your foot ''ready'' on the rear foot break peg though, for the safe side as you may accelerate a little too much and you'll end up going backways hence on the road....
