Ok, i've been meaning to ask this for a while and it applies to both MotoGP and WSB but I noticed it plainly on Saturday at Qatar. End of lap 1 (race 1), Biaggi comes out of of the final corner and nails it down the straight (did anyone see how long he had his front wheel up for?!) and both he and Haga slowly drift to the inside of the track by the pitwall then back across to the outside for turn 1. Like I say i've noticed this in both series on long straights so my question is: Why do they do this?
My theories so far are to either break the tow of bikes following or they are just letting the bike go where it wants to go and not losing speed by forcing it to stay on the outside of the track?

Cheers all.

track flatness? wind? the effect of torque on the rear suspension(compressing it)?

It is exactly what you think. It is all about getting a draft on the competitor to pass, and they move inside to either pass, or block their competitor from being able to pas.

Exactly,they are trying to break the draft that the bike behind can use to slingshot past for a posistion.
A bike that is down 5 mph can use a draft and pass a much faster bike when done properly.

They do it sometimes even when they are alone. I was under the impression that riders save energy by not forcing them to go straight when it isn't necessary.

Getting closer to the wall often times disrupts the "bubble" behind the bike, creating turbulent air and eliminating, or at the very least greatly diminishing, any effective drafting.

That is how Spies won at Losail. The Ducati and Aprilia had the Yamaha by quite a bit, but he drafted and when he was just a few inches from the rear of the front bike, pull out and hopefully having enough speed to get on the inside and out brake the rider.

Ben used the draft to perfection in both races.When he was running 5th in the first race,he used the double draft to take 2 bikes at once to get 3rd In the second race when he was running 3rd he used the double draft , Haga was trying to draft past Biaggi for the lead and he [Haga] ended up 3rd after Ben took advantage of the huge airless hole that Haga created when he was side by side with Biaggi.Those passes were sweet,especially since they came against faster bikes, but the pass on Biaggi in the tight left hander was a thing of beauty.

Thanks guys, helpful replies. I hadn't thought of this also Austin, very interesting.

Yeah go screw yourself SS, when you list here what titles you have won then maybe we'll start racing (instead of talking bullshit which you are always so good at)
