Any cycle worth it's salt can pull a wheelie - getting it up in the air is not a problem. It's bringing it back down without busting anything that's the trick. All that weight comes crashing down pretty hard.
I pulled a couple of wheelies with my VTX. The first one startled the crap out of me. The second time I was trying to do it. The last time was at the last Honda Homecoming. We were winding down to the end of the lights ride in Marysville and the crowds were pushing in on the sides. I forgot mama was on the back and I wanted to do a small burnout in front of the crowd. I revved it up and dumped the clutch and up she came. Imean WAY up.It came right back down and the better half liked to beat my back to death. Little did she know I was probably more surprised and shakey than her.
Of course it can be done. It just can't be made to stay up there, uz the pipes prevent the Wing from getting high enuf to get into a balanced vertical situation. torque & power will lift it, but it stay there long.
