I wish I knew the age range of the ones voting "not cool." I wonder if that could be part of it. I just turned 45 today and I think they are cool. If I were not so afraid of looping the R1 I would ride them like crazy.
Start small with little power wheelies they come up soft and slow and are easy to keep under a foot or two off the ground about 25mph in first and I could bring it up easily, I had a cbr954rr that thing was a mother to keep the front wheel down on when the throttle was manhandled. Remember to keep the rear brake covered clutched wheelies come up fast if it scares you dab the rear and it'll set back down. You'll be miles away from the balance point before you chicken out the first time. Don't clutch up first gear...
