Im confused I thought most sports bikes will role on wheelie in first, second and even third.
Most bikes (600 CC and above) can do it in first. A really torquey (sp?) bike can do it in higher gears. To roll a wheelie ( i.e. no help from the clutch) generally, the bike has to be able to be able to accelerate fast enough to overpower the front wheel.
Now, keep in mind that your bike is between 450 and 500 lbs wet, and the engine as a major weight component, is at the front, and low. Encouraging the bike to stay on the ground essentially.
Really, the issue with wheelies is the same as the reason most any vehicle on the road will never out accelerate us. Power : Weight.
The best way to do wheelies in 1,2, 3, and 4th gears is to get a dirtbike. My KTM 200EXC does roll on wheelies in 1,2,3,and 4. Haven't tried 5 or 6. It weighs 235 lbs, and has gobs of torque. Some times it becomes a matter of trying to keep the front down, rather than letting it up.
At that point also, you're going to be keeping your wheelies where it's safer for you to be doing them. Cops don't appreciate them, and while you're learning especially, crashes are a fact of life. Not to mention the stress and damage that wheelies do to a street bike. (Chain, sprockets, fork seals, I've even heard that the weld where the steering stem attaches to the frame takes a hell of a beating. I'd believe it.)
