Recent airshow here in NZ they did a standing start race between a Pitts Special,Hughes 500 helicopter,Porsche GT-2 race car (something like 750bhp) and a stock Yamaha FZ1.
Race was length of runway,turn and back to the other end for the finish.
As far as acceleration, bike won easy though once (roughly)200kph was hit the Porsche started to pull away though was quickly overtaken by the Helicopter.
When they reached the end of the runway Pitts was ahead, did a fast 180 in verticle, dived back down and was gone back to the start (showing off slightly while inverted) and winning easily. Followed by the helicopter slightly behind, the Porsche and then the bike.
Of course if they'd used a GSX-R 1000, it wouldn't of been a fair contest
