Can someone explain step by step what this means and how it's done?
I'm watching FP3 at Aragon and although I've heard the term a hundred times before, and see the rear tire almost stepping out, I still don't understand the concept or how they do it.

Well, that's exactly what I was asking. Thanks Kwtoxman!
I don't know if that's anything I'll be trying, looks pretty complicated. Lot's of things going on at the same time...

I have seen you do this while riding jd9, not as exaggerated as you see the big boys do it but none the less same principle....but now you are scratching your head, how....:D

Loose gravel??:eek::p

It is not hard to do really, just need to be on top of things and in " the zone "...
My dad loves watching me go into a corner like a bat out of hell. LOL.

Having dirt in your history helps with reaction time and " feel ".

Lmfao! that's a knee-slapper right there! Good humor rooted in truth, yeah? :D :D

My question is, Is it the rear stepping out as the rear tire matches back up to the engine/transmission after downshifting or is it from rear braking? Maybe its both. I try to look closely at their brake foot when they are doing this (on TV) and most of the time it seems like they are not using rear brake as its sliding. I never touch my rear brake but have only felt the rear come loose if ever from heavy engine braking. Just curious, not like I'll ever be trying this on purpose anytime soon.

IT is from downshifting, rev matching your shifts will prevent the rear wheel from breaking traction...

On a MotoGP bike, etc. things are quite different. They have electronics, slipper clutches and finely tunable traction control, all of which would help them do this kind of thing.

Although I've never tried it on the road (Only on dirt with a much lighter bike) I think backing it in is done using the rear brake primarily whilst there's a lot of weight transfer to the front. Seems to me - I wouldn't be able to accurately control partial locking with engine braking from not rev matching.

I don't have a slipper clutch and prefer rev-match every down change so there's no "sudden" engine braking. On a large capacity V-Twin like the RC51 - to make the rear tire need to grip and raise the engine revs by force is a lot to ask of it, especially when about to enter a corner under hard braking. No point in diminishing rear grip if it's not necessary - that's what rev matching will help us do (If you don't have a slipper clutch).

Basically it is just getting the bike pointed where you want with the rear end. It doesn't matter if it is with the rear brake or engine braking. You can see them doing it with their right leg dangling off the peg. It doesn't take much since the rear is already light from heavy braking.

I've never been good enough to do it well. I did get pretty good about modulating the engine braking with the clutch. I've found it to be like a reverse brake lever. The more you let it out, the more it slows the rear down.

Theres a documentary on netflix called faster. It just chronicles moto gp over the years, and they show how gary McCoy kinda of started the whole sliding thing back in the 90's, dont know if it was exactly the same technique your referring to, but none the less fun to watch and wonder, "could I do this?" Ill do that all day on my dirtbike but, man I'd be scared as crap to have the back wheel come out on me on my beloved rc! Sure would be fun on the track though.

I wonder if the techniques are quite different on say Moto GP & WSB bikes. For example the factory bikes (& some satelite bikes, etc) have pneumatic engine valves & drive by wire throttle control. So presumably they can control just how much engine braking they have, or even rev match automatically (seamless gear boxes will pre-engage the next gear & change in fractions of a second compared to conventional motorcycle gearboxes). Presumably using race fuels they run quite different compression ratios too. Some also have thumb-operated braking on the left. So many differences compared to our dinosaurs! :D

One guy I know in the UK who tried to show off to his buddies and back it into a corner unfortunately broke his chain (It must've been in bad condition! :eek:) and smashed his crank case on his GSX- a couple of years ago. :D

That looks more like drifting to me.
Is there a difference?
I have never (intentionally) drifted, does backing it in end up in drifting if you push it?
