The one thing road racing has over MX is speed. The need for speed, theres no doubt about it, Im as addicted as anyone.
Banging through the grearbox of an MXer and topping out at what, 50 mph? Its not particularly exciting on flat ground or asphalt. banging through the gears on any sportsbike, oh yeah!
Still I see the dirt bike as the ultimate 2 wheel design. The reason why, when it comes to circuit racing, 2 wheels offers no advantage, 4 wheels is simply faster.
But MX, its based on natural terrain, make that gnarly terrain. Forget 4 wheels, there aint nothing else designed that can go faster or even get around when theres jumps and drop - offs. Bikes can basically go where nothing else can, then race around it.
Talking whether GP are aware of SX, they definitely are, I know Stoner obviously know Villopoto well, also Dani went to SX. I dont think they are just being polite when they say they come away more than impressed. The thing is you really need to stand there in front of a triple jump ramp to appreciate its insane, its basically a huge wall that practically goes vertical and any sane person would never attempt to jump it, its hard enough just to ride over it. Then think these guys have the throttle absolutely pinned with a minute margin for error, both on the triples and the whoops. .... the whoops are probably bigger than Dani Pedrosa is.
So yeah while speed is a big thing I reckon I could manage to get a GP bike around a track, even pin the throttle on the straight, appreciate the speed. But an SX track, .... no would'nt attempt it, which I'm guessing is the same impression the GP riders get when they see it.
