Sliding the back end/Backing it in

[Gixxerking]

O.k. guys and gals I am real curious about this one? How in the heck do you slide the rear wheel when comming into a turn? I have seen AMA, MotoGP, and World SBK all do it and it seems almost effortless to those guys. Has anyone actually done this, I know a lot of you do track dayz so how is it done?

Ed, the question was posed quite a while ago. However, having never done it myself on anything larger than the 50cc, it's done by loosing traction with the rear by either applying too much throttle, or with the brake. As soon as it starts to slip, modulate the throttle enough to keep the rear spinning/sliding until traction is regained, hopefully when the bike is back straight.

If you've never done it, it will scare the crap out of you and isn't exactly suggested unless you're VERY comfortable on the bike, and know it's exact limit. The danger associated with it is the rear regaining traction when it's not inline with the front, and a high-side will soon follow. At the very least, you'll have to change your huggies...

Anyone else? Track regulars?

With a slipper clutch it seems to lock up the rear just a little bit, so if you are really hard on the brakes, the rear will be very light and might step out just a little bit. You can achieve the same result by stepping on the rear brake, but i think that is a lot more difficult to control (I don't even use the rear brake on the tack).

Sean (GPTECHMAN) is really good at doing that, maybe he can shed some more light on this...

Backing it in is different than power sliding and "stepping on the rear brake". Power Sliding happens when you get on the throttle enough for the rear tire to break traction. Stepping on the rear brake and skidding into a turn is a quick way to highside. You never want to fully lock up the rear. The rear brake is extremely hard to modulate and therefor it's generally frowned upon. Now, backing it in is something entirely different. Backing it in is where you go into the turn HOT and stomp it down 2-3 gears and dump the clutch, and get on the front brakes hard which lightens up the rear. As a result, due to heavy engine braking the rear tire is turning slower than the bike is traveling which in combination with it not having much weight on it due to heavy front braking will break loose. At that point you pitch it over, and aim with the front while the rear swings around. The whole point being that you can brake much later and dive right into your apex.

So, I don't recommend you do this. It takes a lot of skill and your going to end up hurting yourself or your bike. It's generally a technique used by supermotos because they have stronger engine braking being that they're 1 cylinder motors. They also weigh a lot less, and therefor can be tossed around considerably more. The large amount of suspension travel also aids in soaking up highsides. A slipper clutch helps modulate the act and preventing the tire from going too slow. If you don't have a slipper clutch you have to feather it through the turn to get the right amount of rear tire speed. The more you let it out the more it's going to step out.

I did this on my supermoto some, and it's fun. I've also done it on my f3, that was a bit scary. But anyways, this isn't something you should get serious with on the street. Once your pitched over you can't really make a change while the rear is stepped out. Your committed, so your either going to hit whatever hazard is there or highside, choose whichever is 'better'.

When you get good enough you can combine backing it in and powersliding and look supe dope out there like this guy: http://www.youtube.com/watch?v=gELHaZIDJqM&mode=related&search=

Powersliding is the cause of highsides, your flirting with disaster: http://www.youtube.com/watch?v=CCkhAq9rztQ&mode=related&search=

Enjoy, don't go and kill yourself! :thumbsup:

Thanks alot there Tom, Brakstad, and Irk. Don't plan on tryin this anytime soon. I do have a trackday with Fastrack riders on the 22 of April @ California Speedway. This will be my first trackday and will probably become a track wh0re after that.

Where you goin?

Cool... I'll be at WSIR all weekend. Doing the Iron Man...:thumbsup:

Speaking of engine braking, backing it in is fun on an RC too.:thumbsup:

+1 on everything Irk said. There's been a few debates on this on supermotojunkie, but the general consesus is what he said. I can do it a little here and there but not consistanly, but the place is no place to practice it...

Because I have been obsessed with backing it in and own both dirt and street bikes I can shed a little light on the subject. Here it is: Motard riders use the rear brake like maniacs. Dirt bikes steer very well with the rear almost locked and are much less prone to highsides. Just look at videos of guys sliding motards, they are all over the rear brake.

Guys on sportbikes are backing the bikle in using a ton of front braking and a downshift or two. I am by no means a master, but last time I was at buttonwillow I managed to get the bike sideways making a late brake pass going into the sweeper (where the mazda turn usually is). IMO sliding the bike on the sport bike felt much less agressive and required more smooth of an approach. I mean, when I slide on the dirt bike I use a ton of rear and the whole process seems to be sort of agressive and the meaner the better. The few times I have gotten crossed up on my R6 felt like everything happened much more smoothly. I was braking really hard with the front, turned in just a little, and the bike was sideways. The major difference was that the bike felt sideways, but it didn't seem to grip slip grip like a dirtbike does. If you watch the crazy videos of the guys in Greece they back it in for almost no reason using the rear brake.

It can be done using the rear, but if you want to be fast and not just ride for show, learn how to get the bike sideways using the front brake. Ride behind shaggy for a lap or two. You will see smoke dump off the rear tire and the bike seem to get a little crossed up every once and a while. The guy has no dirt skills, he is front brake only my brotha!

In the dirt I use the rear brake, but I don't use it much (or at all) when backing it in. It's all engine braking from downshifting on the pavement.
