庆祝滑胎版成立，分享自己收藏的资料。暂时只有英文版，小链应该可以帮忙翻译一下{:soso_e113:}。

坑爹的Discuz论坛啊，下午在单位好不容易发上来的图文，晚上回家一看就没了！

明天重发。

One of the most spectacular attractions to supermoto is the art of backing it in. It takes some time to master this feat but when executed, it is poetry in motion. The advantage of backing in a supermoto bike is to set the bike up for the turn and scrub off speed. But above all, it’s the rush of sliding on asphalt that is the ultimate thrill.

Backing it in is not always the fastest way through a turn, but when it is necessary it helps to know how to do it smoothly without wasting time or losing control. One common misconception is that a rider must use the rear brake to initiate the slide. The slide actually starts with a combination of front brake, engine braking and the initial lean into the turn. The rear brake is a secondary tool to control speed and the rear wheel. At no time is the rear wheel supposed to lock up or skid due to the rear brake. If the rear locks up, a rider can easily lose control and valuable seconds. Study a pro-level rider and understand that no matter how sideways or flat they get, the rear wheel is always spinning. (过弯的时候Backing it in并不总是最快的方式，但是它可以帮助你理解怎样顺滑的过弯，而且不会掉时间和失去控制。针对back it in，一个普遍存在的错误认识是，应该先踩后刹，让车滑起来。然而，实际并不是这样，正确的做法是通过同时控制前刹和发动机制动，并使身体向弯心倾斜，从而开始使车子滑起来。（这一步其实是挑战自己的心理，丢掉以后的驾驶习惯。当开始测滑的时候，不要尝试去扶正车子。）这个时候，后刹只是第二套方案用来控制速度和后轮的转速。任何时候后轮都不应该因后刹而抱死或者包死而导致跳胎。一旦抱死，你很容易就会失去对车辆的控制。虚心向高手学习（老王？或者谁谁），不管老王那次滑得多么帅气，你都应该知道，测滑的时候，后轮始终都保持在转动的。)

There are a few theories when a rider should put their foot out during a slide. Some have to do with rider comfort while others are all about technique. Riders with dirt track backgrounds feel it helps them set up for the turn but I have found that learning to slide with your feet on the pegs offers more control and it is easier to correct mistakes. At a certain point in the turn you will want to put your foot down, but not until you are just about to hit the apex. I have demonstrated how I back it in, but each rider will slightly alter their style based on their background. As a rider becomes more accomplished, the bike naturally starts to float into the turns—don’t try to speed up the process by leaning on the rear brake and skidding the bike into the turn as it could spell disaster.（这段主要是作者的一些个人看法，如他说有越野经验的人，喜欢入弯前就把脚放下来，有力于入弯的控制。但是作者认为学习滑的时候，把脚放在脚踏上，可以帮助你更好的控制，而且方便你更正错误的姿势。他建议当你到达弯心的时候再把脚放下来。还有就是在联系的时候，千万不要通过后刹，来加快学习back it in的进度）

OK，接下来动作分解。
1: Find a track or area to ride that offers a nice fourth-gear straight with a 160-180 degree turn with ample runoff. As you can see here, I have hit my braking point and have started to initiate the ritual of events. Braking, downshifting and dragging the rear brake slightly. Notice I have also started to lean the bike into the turn direction to help initiate the slide. Body english takes on a major role in learning to back it in. During the slide, a rider can alternate their body weight to control the slide and the angle of the bike to the tarmac.（找块没人（摔了不怕被人看见）又干净的场地或者赛道，能拉到4档的，且是直道后紧跟掉头弯的（显然，新港差点意思）。好开始讲解动作要领，当你在直道一直升档拉油门，拉, 再拉...（有DRZ的车友说3档油门到底也可以），到达刹车点时，首先大力前刹的同时噹噹减档到2或者1档（具体看档之间的齿轮比的差距。），稍微带点后刹并且身体向弯内倾斜，这样可以帮助车辆测滑。不同体重的人可以根据自身情况调整测滑的程度以及车辆和地面的角度。说那么多没用，大家还是请看我的动作！）

（这部分内容都有时间了再慢慢翻译，或者小链帮忙一下{:soso_e113:}）
2: Depending on how tight the turn is that you are approaching, you may need to go from fourth or high gear
all the way down to second and possibly first. All shifts should be made in one action. The key to supermoto is
total clutch control. While motocross racers slip the clutch exiting corners, supermoto and roadracers slip the
clutch going into corners to keep the rear wheel from skidding and hopping. The idea is to bang down your
gears and control the rear wheel action with the clutch. If you let it out too fast or all the way, the rear wheel
chatters. If you slip the clutch in excess, the rear wheel won’t bite the tarmac enough to cause the rear to slide.
In this shot I am in first gear while modulating the clutch engagement to control my slide.
根据你要进入的弯的大小，你可能需要从4档或者更高的档直接降到2档或者1档。切忌，你降两个档位也好，你降三个档位也好，必须是一次完成，即应该在你捏离合与松离合之间完成。对于SM而言，对离合器的控制是关键。越野车手是在出弯的时候切点离合，而SM和公路赛的车手是再进弯的时候切离合，因为这样可以防止后胎打滑和跳胎（这句不知道翻译对了没有）。 Back it in的方法就是迅速降档和利用离合控制后轮的转速。如果离合松太快，后轮会跳胎，如果松太慢，后胎的转速和地面的速度又会形成不了速差而滑起来。在这张照片里，我在降到一档的同时，通过调整离合的切合度来控制滑。

入了一点弯

3: In the third frame I am deep into my
slide but technique still plays a huge part.
At this point I have shifted my weight
slightly to the inside of the bike and into
the turn to maintain control and to start
setting up for the oncoming turn. Clutch
and brake modulation is still key. As the
rear wheel speed starts to slow down and
spin down to the engine speed, the clutch
still has to be modulated to avoid rear
wheel hop until the ratio is one to one.
Braking is very important at this point and
it ultimately determines whether you are
going to hit the apex of the turn or not. If
you brake too early you will be forced to
stand the bike up before the turn, or if you
go in too hot, the bike will float past the
apex of the turn and open the door for a pass.

又入了一点弯

4: The entire idea of the slide is to set the
bike up for the turn. As you start to end the
slide, the bike should be pointing directly
toward the apex of the turn. Notice the rear
is hardly backed out at this point. The main
reason is the rear wheel speed is catching
up to the ground speed. At this time you
are looking to firmly plant the rubber on
the ground for corner traction. However,
you should still be hard on the front brake,
trail braking into the apex in order to keep
the front suspension loaded for maximum
traction. This is also the time I kick out my
inside leg. There is a right way and a wrong
way to do this. Motocrossers stick their leg
straight out with their toes pointing up in
the air. The only contact they make with the
ground is their heel. Simply take your foot
off the peg and put it on the ground with
your toes pointing in the direction you
want to go, just like a dirt tracker.

弯儿深深入

5: The final act is changing direction. As you
can see, I have shifted my body weight back
to the center of the bike. As said before, I
trail brake into the turn to keep the front
suspension loaded for maximum traction.
There is no reason you should ever release
the front brake going into a corner unless
the front tire breaks traction and starts to
skid. If you release the brake too early, the
front end wants to stand up and the bike
will run deeper into the turn. Remember
that if you’re coasting anywhere on the
racetrack, you’re doing something wrong—
it’s either brakes or gas all the time. Rome
wasn’t built in a day so don’t think you’re
going to master backing it in overnight—it
takes time and patience. Mastering braking,
downshifting, clutch control and body position
all in one fell swoop is the ticket. If you
wish to take clutch control out of the mix,
the secret to supermoto is to install a STM
slipper clutch.
