MotoGP - inside leg out through corners

Why do these buggers sometimes hang their inside leg off the peg as they come a little too hot into a corner ?

Balance ? washing off speed ? too used to motoX ?

protect there line ????
whatever you dont, dont try it at a ride day at PI, headmarshall gets his knickers in a knot.
Oh fuck here we go.
nah really, could someone explain it? i have my assumptions, but they're probably inaccurate. is it the new knee down?
it all started off with rossi "just doing it". when asked about he couldnt give an answer as to what benefit it gave him (could be fear of losing the front end on hard brakes).. just that he did it out of instinct. i suspect other riders started doing it because rossi does it just in case it helps lol..

in theory (and why its done in MX) is to put more weight on the front for better grip.. in mx it also helps cos you occasionally do prop yourself with the leg when bike slides..

in road riding i severely doubt that it helps in any way.. even at track days.[hr]

Seems like a good way to snap your leg off at speed.

There were articles about it a while ago in Rapid and AMCN, but it was essentially just for show. There was a slight, very slight change it helped, but yeah, mainly fo sho
I have been wondering for ages too.

cerb if that's true its pretty funny.

tracks that operate exclusively for sumo's obviosuly don't have a problem with it but tracks that host road bikes seem to hate it.
I know Broady dun like it and Shane will attest to the karnt at PI that told him not to do it

Not in high speed stuff.

When I was racing enduro the knee only came out in really slow stuff, where the wheels aren't spinning fast enough to stabilise the bike significantly with gryoscopic effect.

Steve Brouggy's theory that he told us at SBS is that their foot sometimes slips off the rearset under brakes and then they wait until the last second to put it back on. Feasible I suppose.

I've done it to see what it's like, it feels ok I guess.
^^^ well i wouldnt expect shaneo to stick his lge out through t1.. but turn 4 and 10 maybe? dunno.. never rode a SM....

enduro stuff is diff to mx too tho.. in enduro you tend to be standing up all the time too unless like you said, really tight stuff in single tracks etc..

there was a theory that rossi did it for shits and giggles to see if ppl would copy him. lol guess it worked!

i dont think its a matter of their foot slipping off.. stoner does it a lot when you can see he is hard on the brakes. some ppl say its to create bit more air resistance and therefore help to slow the bike that way too.

maybe you should fo stuck ur leg out before ur corner blackness.... but then you wouldn't have that epic gif as your sig!

"the new knee down" according to AMCN.

its done by noobs as well (yes. i did it when i lost the front when i decided i no longer liked the tank on my bike and threw it down the road like a bowling ball)
Well I always had this thought.

If the rider is braking hard - say into a left hander, the bike under brakes will generally have the rear wheel slip out past the centreline of the front wheel to the right and off track due to the gyro effects, lack of wheel contact, g force on the rear weight and braking. To pull the bikes rear back into line, would result in the rider countersteering the bikes front wheel the wrong way - resulting in the bike wanting to stand upright again. So to help with this issue they use the inner weight of the leg (which also creates drag) to offset the rear end slipping around so they can still maintain the correct lean angle and braking pressure.

Also they need to do it towards the apex, otherwise they can't control gear movements. However I've rarely seen this happen on right handers.

Just a thought. And I haven't really gone into to it too technically either.

But most of the guys that do it seem to have a Moto X background as well.

LOL my leg will be comin out every corner of EC from now on! Especially into T1 and entering the pits.:nod:

I always thought that they put it out to help with balancing the bike towards that corner under heavy heavy braking.
Left leg just seems to be naturally easier to hang off rather than the right leg coming into a corner as you have already done major gear changes and the left side of your body can relax a bit more than the right under braking as the right hand side is working the accelerater and brake at every corner.

My confusion 2cents :)
I remember they did an interview with Rossi when he started doing it and he didnt really have a reason as to why, but then another interview later on he said it just "felt comfortable" Its strange but has definitely caught on with the other riders lol.

I have asked so many people this. My own theory is that the speeds they travel at, sticking out their leg provides a little bit of wind resistance and so on. Think drag cars trying to stop.... But steering the bike instead of stopping it. Haven't given it much thought though.
It would have to contribute to reducing speed. These guys are riding at the limits already, and this would have to provide just that little bit more resistance to help shave off some speed... without using traction on the tyres. I've noticed Rossi turns his foot side on to get the most benefit. I've also been wondering if it provides additional turning force too, which takes a slight bit of pressure off the front tyre to turn as tight. All very minor, but at that level, probably the difference between being in the lead pack or the middle group.
