Motorcycle Steering Guide

If we've all been paying attention - and we have haven't we ? our steering is improving. Let's sit up straight as the man at the bars speaks...
If you've been following this series you'll know that we have learnt that to get out entry into a corner right we require a turn point. Now we've established that, where do we put it?

Importantly, you should know that your turn point dictates where the turn starts for you, regardless of the curve of the road. Once located, it becomes the focal point at which you complete setting the speed and begin the control actions of riding the turn. In your sequence of actions to ride a corner from one end to the other, the turn point is the thing that breaks up the transition between speed and directional forces. After all, there are only two things you can change on a motorcycle. You can change it's speed, and you can change its direction. The turn point tells us it's time to be finished with setting the speed for the turn (whether that means decelerating, accelerating or holding a constant speed), gives us the place in which to change the direction of the bike (steer) and then as soon as possible after that we will want to start rolling on the throttle and accelerating out onto the next straight section. It is therefore important that you understand what effect the position of this point will have on the outcome of the corner. There will be a difference on where you will place the turn point depending on what you want from the turn. If you want to go faster, your decision will be different than if you are two-up and trying to take in the scenery.

In the first example your priority is speed, in the second it is comfort. So before you can decide where you will do certain actions you must first decide what it is you want from the corner. As a general rule, the wider and deeper the entry to the corner, the narrower the exit (wider relates to your position on the road in regard to the inside or outside of the turn, and deeper relates to your position in regard to how far into the turn you are) There is however a trade off between this and the speed you are able to carry through the turn, which will relate directly to your motorcycle and how it needs to be ridden to get the most from it. Sound easy? Here's something else to consider... A lot of Keith Code's books deal with the whole 'survival instinct' reaction of your body when you place it in a potentially life threatening situation.

If you aren't used to being wide in a corner, then at least for the first time you'll probably experience the uncomfortable sensations that go along with this. We certainly see that at the schools. Most riders tend to want to get to the inside of a corner as quickly as possible. Perhaps you've noticed that the faster you go, the earlier you find yourself arriving on the inside of the turn, sometimes with disastrous results. Keith suggests a number of ways to overcome this, particularly in his book 'A Twist of the Wrist II' but it really boils down to education. If you know why you should consider entering a little wider and deeper into the turn, you're more likely to try it. Do it a few times and get a good result and you're more likely to want to keep doing it.

Lets assume two riders are travelling at the same speed and steering with the same force. Rider A chooses to turn early and narrow and as a result, this leaves him wide and still leant over late in the exit of the turn. Rider B chooses to steer later and deeper into the turn. This allows him to be more upright earlier and use more power exiting the turn, giving the capability of actually being faster and in more control.
I personally have two goals from any corner:

1.) to be upright at the end of it, and
2.) to be in control.

Bearing this in mind I suggest as you try moving your turn point deeper and wider into the turn, but do it in small steps and carry less speed as you do. Once you're comfortable being out there you'll begin to see the benefits...
'Get around, get around, I get around...' Yeah? Well here's how to do it better with Big Steve.
So... now we know how and where to steer... how many times should we do it in a corner?

This one's easy. Write this down and commit it to memory. 'There is one steering change per corner'. We'll discuss the exceptions a little later. What this means is you only steer the bike once for it to complete the turn. After you counter-steer, to complete the turn, the bike wouldn't really care if you weren't even on it! Okay, that's a little glib, but after steering, all the bike requires from you is to exercise good throttle control to allow it to complete that turn successfully. This is our ultimate goal. If you only have to steer the bike once at the entry of the turn, you no longer need any other input to remain on that arc through the turn. Once you have begun the arc you desire by turning it once at the correct point, all that is left for you to do is to stabilise the bike with the throttle. This alone will keep the bike 'tracking' through the corner. In earlier columns we have discussed the concept that there is a sequence of things you must do to successfully negotiate a turn. It is how well you execute this sequence of actions that determines your cornering outcome. We should be steering the bike only once for any corner and this is an important part of the sequence. Before steering you must have your speed setcorrectly for the corner. If you are still attempting to get your speed right at your turn point, will you be able to effectively steer the bike only once?

After steering the bike, we want to be on the throttle as early as possible and progressively accelerating through the corner. Can you smoothly and progressively apply the throttle if you are trying to make adjustments to the steering? NO

To be effective with any particular action of riding, you must have completed the previous action before initiating the next. In short, you can only do one thing at a time. You may find that on longer corners that you can't just steer the bike once and have it complete the turn the way you want it to. These type of turns are commonly known as 'double apex' turns, but I like to think of them as being two corners masquerading as one. In a double apex corner you do have to make a second steering change to remain on an arc that will see you exit the turn where you want to be. Most times the second steering change is so subtle that riders can do it without even realising it, but make no mistake, it is there. The reason it is so subtle is because the bike is already leaned over in the turn, making the amount of input needed at the bars only a very small percentage of what would normally be required to get the bike to begin a turn from being fully upright.

So how does this second steering adjustment effect our sequence of doing one thing at a time? Well... can you accelerate and steer at the same time? Not really. Can you slow the bike down and steer at the same time? Again, notreally. So how do you get to do the second steering input without upsetting the sequence? Simple really. You must roll the throttle on from the first steering input, otherwise the motorcycle won't track around the first part of the turn. For the second steering change we can't keep rolling the throttle on and we can't exactly roll it off either, as either of these won't get us the desired result. Tricky, huh...

In the first instance you will probably find the bike won't tighten the arc (which is what you're wanting it to do) and in the second it will load up the front of the bike and make it tend to run wide. What you can do though is simply stop rolling the throttle on for a moment. That will not exactly slow the bike down, but it will slow the speed of acceleration, meaning a small amount of weight will be transferred to the front, making it easier to steer. By holding the throttle constant for that moment while you put in the small steering input, you are not interfering with the bike in any other way and it allows you to continue rolling the throttle on immediately after steering, which will once again stabilise the bike. Whether you're in a long corner that requires you to put in two steering efforts, or a short corner where only one is required, if you have tosacrifice speed or position for any part of the turn, you do it in the early part, so you can make gains on the exit.
