Braking by Nick Ienatsch

Nick is a member of another forum I am on. He posted this up and I wanted to share it with everyone as braking is so important. Much of what he talks about we teach in other programs like the Total Control Classes and I thought this would be good to share with everyone as it can benefit everyone.


"If you have to stop in a corner, one of two things will happen. One, you will stand the bike up and ride it off the shoulder and into whatever is over there. Or two, you will lay the bike down and slide off the shoulder of the road. Braking is done before, or after a corner. The best thing to do before taking a corner is to grind the thought "I'm going to turn this corner" into your mind."

Hiya FZ1 lovers.
I’ve stewed for two days about the above quote taken from another FZ1OA thread...and finally decided to launch this thread. In past years I would have just rolled my eyes and muttered, “Whatever”…but not anymore. I want to tell you that there are measureable, explainable, repeatable, do-able reasons that make great riders great. And brake usage is at the very tippity-top of these reasons. It’ll save your life, it’ll make you a champion. It will save and grow our sport.
I’ll ask this one favor: Would you open your mind to what I’m about to write, then go out and mess around with it?
To begin: Realize that great motorcycle riding is more subtle in its inputs than most of us imagine. I bet you are moving your hand too quickly with initial throttle and brakes. Moving your right foot too quickly with initial rear brake. The difference between a lap record and a highside is minute, almost-immeasureable differences in throttle and lean angle. The difference between hitting the Camaro in your lane and missing it by a foot is the little things a rider can do with speed control at lean angle. Brakes at lean angle. Brakes in a corner.
Yes, a rider can brake in a corner. Yes. For sure. Guaranteed. I promise. Happens all the time. I do it on every ride, track or street. Yes, a rider can stop in a corner. In fact, any student who rides with the Yamaha Champions Riding School will tell you it’s possible. Complete stop, mid-corner…no drama. Newbies and experts alike.
There are some interesting processes to this sport, mostly revolving around racing. But as I thought about this thread, putting numbers on each thought made more sense because explaining these concepts relies on busting some myths and refining your inputs. Some things must be ingrained…like #1 below.

1)You never, ever, never stab at the brakes. Understand a tire’s grip this way: Front grip is divided between lean angle points and brake points, rear grip is lean angle points and acceleration points, lean angle points and brake points. Realize that the tire will take a great load, but it won’t take a sudden load…and so you practice this smooth loading at every moment in/on every vehicle. If you stab the brakes (um...or throttle...) in your pickup, you berate yourself because you know that the stab, at lean angle on your motorcycle (and bicycle, btw), will be a crash.

2)Let’s examine tire grip. If you’re leaned over at 95% (95 points in my book Sport Riding Techniques and fastersafer.com) of the tires’ available grip, you still have 5% of that grip available for braking (or accelerating). But maybe you only have 3%!!! You find out because you always add braking “points” in a smooth, linear manner. As the front tire reaches its limit, it will squirm and warn you…if that limit is reached in a linear manner.
It’s the grabbing of 30 points that hurts anyone leaned over more than 70 points. If you ride slowly with no lean angle, you will begin to believe that aggressiveness and grabbing the front brake lever is okay…and it is…until you carry more lean angle (or it’s raining, or you’re on a dirt road or your tire’s cold…pick your excuse). Do you have a new rider in your life? Get them thinking of never, ever, never grabbing the brakes. Throttle too…

3)If you STAB the front brake at lean angle, one of two things will happen. If the grip is good, the fork will collapse and the bike will stand up and run wide. If the grip is not-so-good, the front tire will lock and slide. The italicized advice at the beginning was written by a rider who aggressively goes after the front brake lever. His bike always stands up or lowsides. He’s inputting brake force too aggressively, too quickly...he isn't smoothly loading the fork springs or loading the tire. He may not believe this, but the tire will handle the load he wants, but the load must be fed-in more smoothly…and his experience leads to written advice that will hurt/kill other riders. “Never touch the brakes at lean angle?” Wrong. “Never grab the brakes at lean angle?” Right!
But what about the racers on TV who lose the front in the braking zone? Pay attention to when they lose grip. If it’s immediately, it’s because they stabbed the brake at lean angle. If it’s late in the braking zone, it’s because they finally exceeded 100 points of grip deep in the braking zone…if you’re adding lean angle, you’ve got to be “trailing off” the brakes as the tire nears its limit.

4) Radius equals MPH. Realize that speed affects the bike’s radius at a given lean angle. If the corner is tighter than expected, continue to bring your speed down. What’s the best way to bring your speed down? Roll off the throttle and hope you slow down? Or roll off the throttle and squeeze on a little brake? Please don’t answer off the top of your head…answer after you’ve experimented in the real world.
Do this: Ride in a circle in a parking lot at a given lean angle. That’s your radius. Run a circle or two and then slowly sneak on more throttle at the same lean angle and watch what your radius does. Now ride in the circle again, and roll off the throttle…at the same lean angle. You are learning Radius equals MPH. You are learning what throttle and off-throttle does to your radius through steering geometry changes and speed changes. You are learning something on your own, rather than asking for advice on subjects that affect your health and life. (You will also learn why I get so upset when new riders are told to push on the inside bar and pick up the throttle if they get in the corner too fast. Exactly the opposite of what the best riders do. But don’t believe me…try it.)
Let me rant for a moment: Almost every bit of riding advice works when the pace is low and the grip is high. It’s when the corner tightens or the sleet falls or the lap record is within reach…then everything counts.
“Get all your braking done before the turn,” is good riding advice. But what if you don’t? What if the corner goes the other way and is tighter and there’s gravel? It’s then that you don’t need advice, you need riding technique. Theory goes out the window and if you don’t perform the exact action, you will be lying in the dirt, or worse. Know that these techniques are not only understandable, but do-able by you. Yes you! I’m motivated to motivate you due to what I’ve seen working at Freddie’s school and now the Champ school…
I’m telling you this: If you can smoothly, gently pick-up your front brake lever and load the tire, you can brake at any lean angle on and FZ1. Why? Because our footpegs drag before our tires lose grip when things are warm and dry. It might be only 3 points, but missing the bus bumper by a foot is still missing the bumper! If it’s raining, you simply take these same actions and reduce them…you can still mix lean angle and brake pressure, but with considerably less of each. Rainy and cold? Lower still, but still combine-able.

5)So you’re into a right-hand corner and you must stop your bike for whatever reason. You close the throttle and sneak on the brakes lightly, balancing lean angle points against brake points. As you slow down, your radius continues to tighten. You don’t want to run off the inside of the corner, so you take away lean angle. What can you do with the brakes when you take away lean angle? Yes! Squeeze more. Stay with it and you will stop your bike mid-corner completely upright. No drama. But don’t just believe me…go prove it to yourself.

6)Let’s examine the final sentence in the italicized quote. The best thing to do before taking a corner is to grind the thought "I'm going to turn this corner" into your mind.
No, that’s not the best thing. It’s not the worst thing and I’m all for positive thinking, but we all need to see the difference between riding advice and riding techniques. This advice works until you enter a corner truly beyond your mental, physical or mechanical limits. I would change this to: The best thing to do before taking a corner is to scan with your eyes, use your brakes until you’re happy with your speed and direction, sneak open your throttle to maintain your chosen speed and radius, don’t accelerate until you can see your exit and can take away lean angle.
7)Do you think I’m being over-dramatic by claiming this will save our sport? Are we crashing because we’re going too slowly in the corners or too fast? Yes, too fast. What component reduces speed? Brakes. What component calms your brain? Brakes. What component, when massaged skillfully, helps the bike turn? Brakes. If riders are being told that they can’t use the brakes at lean angle, you begin to see the reason for my drama level. When I have a new rider in my life, my third priority is to have them, “Turn into the corner with the brake-light on.”

I’ve said it before: This is the only bike forum I’m a member of. I like it, I like the peeps, I like the info, I love the bike. Could we begin to change the information we pass along regarding brakes and lean angle? Could we control our sport by actually controlling our motorcycles? If we don’t control our sport, someone else will try. Closed throttle, no brakes is “out of the controls”. Get out there and master the brakes.
Thanks, I feel better.

I think good riders can ride with or without braking in curves. Generally IMO it's better to practice the following drills (not necessarily in this order, but #4 is definitely last):

1. Ride your favorite twisty road without the brakes, using engine braking to set your corner entry speed (for most riders, especially new riders, this will require a lower gear than he's used to).

2. Ride your favorite twisty road in one gear, without shifting, but practice using the brakes smoothly for speed control as necessary.

3. Ride your favorite twisty road in one gear, without shifting, and without brakes.

4. If you can do all that smoothly, you will find that you can now go faster if you shift frequently and use the brakes, but this results in a pace that is basically insane on the street. On my bikes ground clearance is enough of an issue that a faster pace leads to hard parts dragging and scary moments where the rear tire loses touch with the pavement. So I don't push it any farther. But I can't quite master #3 anyway.

Nick is correct on every point.

I've been told multiple times by multiple members here that my regular use of trail braking should be left on the track. They really need to read and heed the above.

Thanks for that ... an interesting read.

Braking techniques have many nuances

I think of it as a bit like handling testicles ... squeeze too hard & too quick and you might not get a great result (blokes can substitute boobies for this analogy)

Thanks for the post. I brake in corners almost daily.

Hold to the "Smooth is fast/fast is smooth" saying and there is a lot of usable traction to play with.

Trail braking has many advantages on the street, as DAKEZ put it, Smooth is fast/fast is smooth.

Now what are the skills to be smooth? Throttle transitions, and throttle to brake and brake to throttle transitions, and trail braking are the places to start.

What? Braking in corners?? Next you'll be telling us to use the front brake and everyone knows that will send you over the handlbars. Enough of this crazy stuff!! All you need to be safe on the street is learning how to "lay er down" properly.

And if you haven't mastered that technique, at least wear some assless chaps for protection.

TY, i like Nick and that was a good read.

Nick wrote The Pace in 1993 and it was/is a must read too.

Excellent read.

A traction question: Let's say that a given stretch of clean pavement has a "traction value" of 100 on a warm dry day. Is there a rule of thumb for how much that number would decline on the same road during a hard rain (that has washed off the residual fluids deposited by cars)?

Too many factors, slope of the road, how fast the water is running off, your bikes suspension, tires etc. temperatures and of course tire temps. just way to many variables.

Those factors are constants. The only thing that changes is the wetness of the road (or I guess you could say the coefficient of friction).

Air tempeture usually drops with rain, water on the road will also cool your tires, and as I mentioned slope of the road determines the rate at which the water is running off the road, or put another way how deep the water you are running through is. All roads are sloped for this purpose, some more than others.

OK, is there some rule of thumb that generally takes these factors into account?
