Ok i see lots of times people asking, wanting to learn, people who sometimes don't have the money to spend for a school (you should try though) or people who don't have anyone to show them (the proper way).
I wrote this small article intended to provide a little info regarding body positioning.
So we always hear about proper riding position and knee dragging and new riders get even more confused.
The purpose of this small article is to help rider (new, more experienced it doesn't make a difference)
understand proper riding position on your bike.
What is proper riding position? And who the hell does judge what your riding position should be? Well the
judge is physics and the how we are just going to analyze.
How many times have you approached a turn and felt frozen started thinking of traction, speed, body positioning
and a hell of a deal of other things. Did that moment make you think that you are not going to make it through?
If it did (if you say no…you are probably lying to yourself or you haven’t….ridden yet) don’t be worried its
absolutely normal to get a scare, even experienced riders do have them time to time (try checking a few magazine
videos, I know of a couple where you can hear the breathing from inside helmet cameras) it’s how your mind reacts
to a danger situation and how it tries to prepare your body for something that might go wrong.
The first and most basic things you need to understand and get really familiar before moving to body positioning
is throttle control, braking, counter steering and overcoming your fears the rest such as body positioning and
cornering art (lines, speed, time saving techniques) are not to be experiment with if you haven’t got familiar
with those basic issues. Believe me it might be fancy getting outside the bike and trying to lean all nice and
like a motogp star but it is not any help if you don’t know how your throttle works and how it affects suspension,
corner speed and traction control.
If you want to learn more regarding those things I would suggest you attend a bike school (something like CSS)
it is really worth the money even if you think that you have mastered these techniques (just ask a few professional
riders).
Now on to body positioning, the first and most important aspect of cornering is to understand what exactly affects
a motorcycle while cornering either at the start or the middle or even the exit of a corner.
So let’s see some important factors regarding cornering:
• Your bike is designed to handle a distribution of load, you don’t have to know physics to understand
that most of the weight distribution under extreme conditions should be handled by the rear part of your motorcycle,
just look at the tires, the small front and the huge rear state this. Technically speaking a bike is working correctly
while cornering when the weight distribution is around 30-40% at the front part and 60-70% at the rear this weight
distribution is directly affected by throttle and brake handling (thus the mentioning of them previously).
• A bike turns with the counter steering technique, this roughly (my intension is not to present what counter
steering is through physics laws –we can do that on a different thread- ) means that when you turn you apply gentle
pressure to the handlebars to the opposite direction (you want to turn left, you apply pressure –watch it pressure,
not pulling- to the left clip-on and vice versa).
• You use the knee as a lean angle indicator, ok it’s nice dragging the knee down and gives a more talented
“look” to the rider, but the knee is there only as an extra (and free) instrument, it tells you how much lean angle
you have at the moment, usually us mortal riders will stop leaning after the knee has touched the ground.
• Handlebars are for steering, they are not for holding on them, this is vital and crucial to understand,
and you use the clip-on’s as levellers for pushing you don’t rest your body weights on them.
• The heaviest part of your body is your torso and your head, this is another crucial factor, you need to
remember that hanging off does not mean moving your butt outside the seat, it means moving your body I see more
and more often people hanging off but only their leg is sticking outside the bike, this is wrong. I know you have
seen it done from MotoGP riders but you aint got neither their skills (maybe some of you…but you wouldn’t be reading
this) neither the motorcycle parts (suspension, tires) nor we are talking about different circumstances and different
techniques.
• Chicken stripes (duh) are not an indicator that you are leaning correctly, they are an indicator of your
lean angle, if you don’t move your weight to the inside of the turn and your tires have no chicken strips it means
that you have higher chances of crashing from a rider who positions his body correctly for a corner.
But now lets start, there are many different techniques of hanging off the bike but there are common rules which need
to be followed for achieving it correctly.
The first rule is that you need to move your body out of the seat and inside the turn, then you need to do this in a
manner which does not disturb the bike, which would create problems and finally you need to have your hands relaxed
and not pressing on the clip-on’s
So what is the procedure of cornering and body transition from side to side? (as mentioned above there are different
ways of doing this, but you should always remember the common rules, bellow I will describe the way I prefer).
• I always prefer to position my body before I start braking; this helps me because under heavy braking body
movements will disturb the bike (again for us mortals, racers usually can do it without any problems). And if I try
to position my body after braking (which would be the start of the corner) again I might disturb the bike. So before
you start braking move your inside butt cheek outside of the bike (for example approaching a left turn you would move
your left cheek to the outside of the bike) so much that only the opposite butt cheek rests on the seat.
• Again before braking I prefer of positioning my legs properly so that I don’t need to adjust my positioning
during cornering. So I usually rest the ball of my inside foot to the edge of the peg, this helps me because of my
height if I rest the ball on my peg I won’t be able to easily open my leg later (there is no correct or wrong at this,
you need to find which is more relaxing and easily achieved for you). Note that you should be carefully positioning
your leg, if you toes extend far to the ground there is a big chance of injuring them (I’ve seen riders breaking
their toes while scraping the rear-sets).
Your outside leg should be placed normally on the rear-set but you need to make sure that it allows you to put
pressure on it, since its going to replace your hands on body movement later plus you will use it as a suspension
extension.
• When you have finished positioning your body you should actually start the braking of the bike, this is
another crucial step of cornering and it’s crucial that it is performed correctly.
One major error that new riders perform most often is shifting weight to the front system (suspension, tire) while
braking, this is a major reason of some crashes, your hands should be resting you should not be pushing the clip-on’s
while braking because they only thing you achieve is moving more weight to the front end system, more weight
distribution means higher chances of loosing traction and crashing (remember the 40% - 60% rule mentioned?) I
know I can hear you asking how you maintain your body positioning on the bike while braking, and the answer is
between your legs (eh…not that) your tank! Grab the tank with your outside leg (right leg for a left hand corner)
and push against it to maintain your body positioned, push also down your outside leg so that your body does not
disturb further the bike. While you are braking always remember that you don’t let your brakes go free while
heavy braking, you need to smoothly release the brakes because if you don’t you are disturbing even more your
front end system (sudden release of the brakes means quick suspension rebounding which disturbs your bike again).
• While you are smoothly releasing the brakes, start lowering your torso, this is vital! And most times
forgotten or done the wrong way, the heaviest part of your body (as mentioned again before) is your torso and your
head, not your waste nor your legs, it’s the upper body which needs to move for proper hanging off. Also note that
you are not pivoting around the tank, you are moving sideways outside, pivoting is not wrong but its hard to do it
correctly when you are a novice rider (regarding body positioning) I see most of the people pivoting that they have
their torso quite high and above the tank this is totally wrong since your body needs to move to the outside. So
start lowering your torso and bend your elbows if you don’t bend your elbows you won’t be able to lower your torso
and there is a big chance that you will be applying pressure to the handlebars.
One technique that helps your get the correct body positioning is called “kiss the mirror” that’s the technique
that will produce you the best results regarding the positioning, it is achieved by bending your hands, and moving
your torso towards the mirror in a position like you are trying to kiss it. This means usually that the inside hand
should be bend around 90 degrees (to give you and idea), a small part of your torso should be touching the tank
(the inner part should be hanging off) and your outside hand (right on a left hand turn) should be resting on top
of the tank. While you are lowering your torso point your inside knee to the inside of the turn (try to move it
around 40 – 45 degrees to the inside of the turn).
Again remember not to put pressure on the handlebars / clip-on’s you are just touching them and using them to
counter-steer nothing more nothing less. This movements are performed while the bike is coasting (it’s the part
where you have finished with the brakes, you keep the throttle steady –maybe just a tab of roll off to use also
the engine break- ).
• Once you have finished with body positioning you should be in the entrance of the corner, now you either
keep the throttle steady or you start opening it, but never, never (unless you are an experienced rider) back off
or hit the brakes, you need to try to maintain the 40% - 60% weight distribution and that’s done at this time by
throttle control.
• Your outside foot should start pushing on the rear-set, this will transfer the center of mass further down
(from the tank to the peg), this is achieved because you are pressing down the peg and not the seat or the tank,
the peg is lower than the other points and thus you get a transfer of the center of mass.
• Always look at the vanishing point this is the only way to properly ride through a corner, you don’t look
down, you don’t look outside, you don’t look inside you look at the end of the corner, this way your brain reads
the corner and provides the proper information to the rest of your body parts to move correctly, where you look is
where you go, sounds strange but that’s how it works, look outside of the corner and you will end up there.
• The first times you will try you probably are not going to be dragging a knee, that’s normal you don’t drag
a knee to impress people, you use it to understand how much lean angle you got there, but I know surely that you
will start feeling totally different, you will instantly start understanding how wrong you where riding and how
much more confident you will feel. Now once you tried a few times look at your tires, woa yes you got chicken
strips (unless you got mad lean angles and you where dragging your knee) maybe a bit big, but that’s an indication
you are moving correctly, your bike now needs less lean angle to make it through a turn, and surely you feel you
can use even more throttle. Well if you feel that, then you surely do understand why you hang off the bike, you
don’t do it to look like Rossi (well you like to look like him I am sure J ) you do it to allow yourself to ride
better, quicker and safer.
• All of the above movements are done usually rather quickly and you must practice to make them without
disturbing the bike. It’s going to be difficult since you will feel that you can’t handle the bike properly at
the time you start hanging off, but I can assure you that it’s far safer to hang off rather than stay on! Off
course this means you are practicing on a track or somewhere that there is no traffic or other kind of obstacles
which could put your life or health in danger.
• Don’t try to drag a knee if it doesn’t happen the first time, chasing such a thing could put you in
danger, know your limits, if you start feeling you are riding above your skills and your limits then call the
day off, you will achieve this by practice but maybe not the first day.
• This article is not complete, as mentioned in the begging there are many other aspects needed to be
controlled and understood before trying to move to this, you should attend a school where you are taught and
“monitored” by the instructors.
• If your corner is a really slow speed corner then hanging off might not be necessary since its more
effective in higher speeds, again a small transition of body weight will help you turn more easily, but don’t
try to hang off if you are not experienced.
Some picture note the difference in lean angles to understand how your body affects it.
