When I worked at Yamaha Suzuki
Sports Center in Seaside Cali, I was known as Super K, the wheelie king! Not to toot my own horn, but I can basically wheelie anything. I don't wheelie very long anymore because since Im almost 40 I am a little more safe. I have wheelied a Yamaha Venture
Royalle for about 6 blocks, so I doubt the "Wheelie Wing" pic is photoshopped. I can wheelie a Wing no problem. If ya have one Ill proove it. I own a 1996 XR600R Supermoto, and that thing will come up easy in third but I have to jerk on the bars a bit. It is actually easier to wheelie with your left knee on the seat, foot over the right side of the bike, and right foot on the brake pedal in case you start to go over. You can even put your left foot down after snatching it up to shift. On an XR though, Id stay away from trying to wheelie for long distance when you are first learning. Try it in steps, like one for about 20 feet, then 40 then after getting used to throttle control and powerband
, you will be able to go further.
