quite a bit of aerodynamics over a stock busa actually, maybe a stretch job too, and what, a turbo?
The accomplishment is in the guys moxy on two wheels, not in anyone's understanding of power and aerodynamics methinks or some innate busa mystique, certainly not an exercise in fuel efficiency
470mpg on real roads with a 185cc bike is seriously impressive, on an economy forum anyway (and that was 26 years ago!! )
