a page or 2 ago, there was a post by becky saying there is no male advantage in racing. now im a biker and in this side of racing, there is, and it becomes more evident as you climb the ranks. its hard to muscle a hugely powerful bike around when it has so little weight.
eg
although not a girl) danny pedrosa, on top the the motorcycling world in Moto GP, rides a 260bhp honda that weighs in at about 140kg(poss less) he weighs a meger 49kg, and although he can be very quick, he gets worn out at the end of the race(evedent in the recent jerez round1)
though i ahve been whooped by some girls in club events, its all about how much talent you have, and how much your willing to work on that.
