It takes alot of speed, brakes and more importantly SKILL. You may have the skill but you don't have the speed and brakes w/ a DR350. It looks great and I think it would be cool to do, but that isn't a race. That's 2 great riders railing a track for cameras. If dragging an elbow was the fastest way around the track then more people would do it. If you insist on more ground clearance, raise your pegs, and get short pegs or make them yourself. Fastway makes shortie that are pretty cool.
Here's a better pic of a guy leaned over.
