Brake/Down Changing Gears Like a Pro

Barriers Open Doors

To make real improvement there must first exist a real barrier to overcome or a real result to achieve. These are always based on the rider?s own desires: to go faster; be more in control; have fewer panic situations; put it all together into a smooth flow or simply remove doubts and questions they have relating to those goals: when do the tires slide, how hard can I brake, how far can I lean the bike and so on.

When you look at it you?ll see that there is very little difference, if any, between a riding barrier and a riding goal; they both have the same stumbling blocks. They both have an end result to achieve. They both have some fear or uncertainty or distraction attached to them. There is always a barrier.

The Braking & Downshifting Barrier

An example of a common barrier would be the complications that arise from the hurried and slightly frantic control operations that stem from not learning to smoothly and simultaneously brake and downshift for traffic lights, obstructions and, of course, corners.

Doesn?t sound like a life or death threatening situation but when inspected closely you see what impact it really has on a rider?s attention and how they are spending it.

Check it out, if the rider can?t do braking and downshifting, simultaneously and smoothly, they are forced into one or more of the following attention draining scenarios:

1. Slowly letting out the clutch to make the downshift smoothly. This requires attention to be spent and is the most common way uneducated riders handle it.

2. Having to change gears once the bike is stopped. When the bike is stopped even the best transmissions can be sticky. Gears change more easily and more positively when the bike is moving. It causes less wear on the gearbox to change the gears while you are moving.

3. Having to change the gears after the braking is completed for a turn. That means doing it in the curve. This is distracting and can upset the bike, to say nothing of the rider.

4. Alternately going from the brake to the gas to match revs for the downshifts. This has the bike pogoing at the front. It does not get the bike slowed down quickly in an efficient manner. This is very busy riding.

5. Downshift before braking. This is fine for very relaxed riding situations at slow speeds but is hazardous to the engine if the rider is in ?spirited cornering? mode as it provides the opportunity to over-rev the motor and bypass the rev limiter that protects it. Could be very expensive. In an emergency situation you don?t have time to do this because you should be on the brakes right away. Not only that but some emergencies require you to brake and then get on the gas right away for accelerating hard to avoid things like cars running a light on you. In this case the rider would not have the time to get it done.

6. Forget it entirely and just go through the corner. This forces downshift(s) to be done at the corner?s exit thus losing the drive out and complicating the whole thing by having to make a gear change when they should be rolling on the throttle. This is distracting and not smooth at all.

Coordination And Concentration

It is true that if a rider was uncoordinated and attempts simultaneous braking and downshifting it could be dangerous. For example having the front brake on along with the power can make your front wheel lock up.

On our panic-stop training bike I have seen it many times: the rider aggressively squeezes the brake and unconsciously rolls the throttle on at the same time. It?s spooky to watch. So yes, practice and coordination are necessary, you will have to practice.

More importantly, you have to make a decision. Are the 6 potential distractions above likely to get you into trouble? They do break the rider?s concentration even if only slightly. In other words: if you aren?t a super hero at multitasking each of the 6 is a negative in comparison with braking and downshifting simultaneously.

In Control = In Communication

Continuous perception of your speed is how you control it. Accurate turn entry speed is critical to good, confident cornering. If you are worried about your speed, you are distracted by it.

Finding the right turn entry speed (for you) is far easier when the braking and downshifting are happening in one continuous flow of change. When compared to one that is chopped up, incomplete or creates anxiety like having to shift in the turn, it?s obvious which scenario is better. Your Sense of Speed is a precious resource and is far more accurate when monitored as a steady stream with your awareness.

Maintaining a continuous state of awareness of what the bike itself is doing is another of the true benefits of this technique. You always know where the engine speed is in relation to the road speed and that improves your feel for the bike.

Your communication with the machine improves; no false signals or guess work; no waiting to know how the bike will respond in any of the above scenarios. You ability to maintain communication with the bike is important input.

Naming It

Simultaneous braking and downshifting. I?d like to shorten it to something like brake-down. Car guys call it heel and toe, which is a nice, short and simple way of saying they are simultaneously using the brake pedal with their toe and revving the motor with their heel. In some cars you just put the ball of your foot between the brake and gas pedals and rock your foot side to side to do it, it depends on the pedal arrangement. On a bike, provided the brake lever is comfortably adjusted to fit your hand, they are always in the same position for our maneuver.

Alright, for now it is brake-down. It would be interesting to have a non rider hear about you executing a ?breakdown? coming into a curve; sounds pretty dangerous. How about fist and fingers or palm and fingers or B&Ding, ?

Whatever we call it, it works to simplify corner entries and puts the rider in command of and in communication with his machine to the highest possible degree.

The Sequence

1. Gas goes off.
2. Brake goes on.
3. Bike slows some.
4. Clutch comes in.
Maintain brake lever pressure.
5. Blip the gas rapidly on and off. (Usually no more than a quarter turn).
Maintain brake lever pressure.
6. During the blip make the gear change positively and quickly.
Maintain brake lever pressure.
7. Clutch comes out.
Maintain brake lever pressure until desired turn entry speed is achieved.
8. Release brake smoothly.

Bear this in mind: the quicker you do steps #1 through #7 the better.

Brake Lever Control

Expert use of the brake during this entire cycle means that you can maintain, increase or decrease the pressure as desired, without abruptly stabbing or releasing the brake lever.

Number of Fingers

Some riders let their finger(s) slide over the brake lever as they blip the gas. Others grab the brake lever with the tips of their finger(s) and still get a continuous lever pressure without the bike pogoing up and down.

Whichever way you do it is fine. How many fingers you use for the brake is up to you: one, two, three or four, this is your choice although I recommend you try just two fingers, your index and middle ones.

What?s Important?

Braking is important, it is life and death on the street and vital on the track. Changing gears is not. You can still make it through the corner or get the bike stopped without ever touching the gears. But, riders do have the six above scenarios to contend with if they can?t do the fist/finger, down-brake, palm/finger, B&Ding technique.

Learning How

The fact that riders have a problem doing this technique led me to a solution. I?ve built a bike that trains it. We call it the Control Trainer. It takes you through the technique, step by step.

The trainer?s computer program talks you through the whole sequence and it points out your problems and how to correct them. The computer is hooked up on a static ZX9, you can?t ride it but you do get the coordination/muscle memory necessary to do it for real.

Each of the controls is monitored for: correct sequence; correct timing of the clutch and gear changes; correctly sized throttle blips and consistent brake pressure, throughout the whole process.

With or without my Control Trainer, anyone can learn to do it. Start now.

i think v-twins are harder to down shift good because of the engine braking but i think i do it fairley wel couldn't tell you what i do. but i will remember this in the spring when the bike comes out to play again and see if this works for me. thanx for the info.

It took me a few months of doing it on the street, but I can now do it smoothly 90% of the time.
Seemed impossible at first, but it come in time, you just have to find the hand position you are comfortable with. I prefer the "let the fingers slide" technique.

This is soemthing I need to work on. Most of the time, on the roads that I ride, I never go hard enough up hill to need to do this, and I don't usually go hard enough downhill on all the corners so that I need to use the brakes instead of just engine braking. Yeah, my back end has gotten squirrely enough from using a bit too much back brake when the downshift happens to know I need to work on it.

I read Twist of the Wrist II so many times before actually getting my first street bike (the SV) - that I have those little tips in mind all the time. I also used to race SCCA and have the heel-toe piece down pretty well. I haven't noticed any pogoing in spirited riding, but I probably haven't been nearly as spirited as some of you get on the street.

There is a lot of advice in the MSF that is intended to keep things simple and safe for the new rider. As you get more experience you will learn there are better (but more complicated) ways to do things that take more skill to master.

this has been talked about before...havent read the book, but have read this passage.

On my SV, I don't feel any reason to do this...or, I havent yet. I downshift without blipping, and just let the clutch out smoothly...not super slow, but certainly not fast. The engine will kinda rev itself as the clutch comes out, and engine braking starts. Then give some front brake if needed. SV seems "torque-ey" enough to pull itself out of most any curve by downshifting just one gear from where I was before (errr...did that make sense?)

Most of my miles are commuting...and I am still a n00b. So maybe I just don't get it, or I haven't reached the level of riding you guys have.

if you can achieve your desired speed and exit gearing without brake (somehting you can usually do with the SV on the street) why use the brake at all

keith code makes things more complicated than they need to be

+1 Ivan, but havent tried the 2000 rpm thing, i have it at about 1450......

Clutch control, You got it gahdzila. 44 years of practice I thinck I have it wired. Use your clutch lever like a brake lever in reverse. down shift and feather the clutch out SLOWLY to use the engines braking. No slipper clutch needed.

Yes, yes he does. He is a good teacher ::) but some of the things he teaches just don't apply to the real world. I've never been that impressed with him.

you should have borrowed EX-250, you'd learn it in a day ;)

1. Slowly letting out the clutch to make the downshift smoothly. This requires attention to be spent and is the most common way uneducated riders handle it.
Uneducated my ass. The clutch isn't just an on/off switch. I let the clutch out slow & smoothly and it's second nature. What requires attention is blipping like he states to do it and I feel 1000x's safer doing a slow release. Correct me if I'm wrong, but isn't a slipper clutch the same as doing a slow release?

I have used the slow release method in my cars for years (my current car has 76,000 miles on the original clutch). Slow release is just fine for the road. I do understand the benefits of rev matched downshifts, but I think it's much more relevant to spirited riding/driving as opposed to normal driving.

90% of the time I do as the way Code describes, I've just hardwired myself to do it that way.
As for the blipping, I ride a 650 single, if think a 650 twin has alot of engine breaking....... not to mention the fact that the KLR has something like 42 feet of suspension travel to nose dive through. Piont being blipping & slipping make a lot of sense for me. Even on my SV's I did it, though I could get away with not alot easier.

Right on Merlot, you got it figured out. I love the on/off switch statement.  ;D   jd

1... roll off throttle on SV, you slow down without touching brake,  notice I say roll off, you chop the throttle completely, you will slow down dramaticly, prolly slower than you want to be going, maybe enen lock the rear tire

5... blip the throttle (no more tha a quarter turn) I hope not, a quarter turn is FULL throttle

Code's advice might be right for an old UJM 2 stroke, or on a track,

I agree, plus it's a lot of fun once you get the hang of it.

For someone who is well practiced it may also mean smoother and quicker deceleration in an emergency situation when you need to be turning as well - maybe not a huge improvement, but enough to avoid contact or going down in a specific set of circumstances. Many things that can work well on the track (trail braking, for example?) seem irrelevant on the street until you consider an emergency situatuon when having that extra ingrained skill could save your butt.

I went to Kieth Code's Superbike racing school over 20 years ago and one of the most useful things I got out of it was this: Use the engine to go and the brakes to stop. Using the engine to slow down to any great degree isn't going to work, it's a waste of concentration. Slow down with the engine as you aproach the corner, brake and corner, as you reach the point of re-acceleration tap down the appropriate number of times for your exit speed, let out the clutch, accelerate out of the turn. All this coordinating of shifting and gas just detracts from your ability to go around the corner.

:-\ This just sounds like a load of malarky to me (considering the bike we are talking about). The SV650 has LOADS of engine braking...it DOES work...and, IMO, requires much less concentration than trying to clutch, shift, brake, and throttle blip simultaneously.

clutch in, release throttle, shift down, ease clutch out, a little front brake only if needed (frequently not needed), accelerate through turn.

I'll be the first to admit that I am inexperienced and not even close to pushing my bike to its limits...but this blipping/braking/downshifting thing just sounds complicated and IMO would be far more distracting on the street than just about any other method.

I may have misspoken, the SV has tons of engine braking and I use it constantly for slowing down as I approach the corner. What I meant was trying to down shift and slow down to the point of sliding the rear tire due to downshifting into too low of a gear.

IMO

Braking/blipping/downshifting isn't very necessary for street riding; especially not for bikes with plenty of engine braking.

On the track, it's a whole 'nuther thing. I haven't done a track event on 2 wheels but I've done enough on 4 to know it's a good skill. Whether it's necessary or not, I find it fun. You'll also find that unless you're doing some SERIOUS braking, it will be tricky braking and downshifting simultaneously while being smooth. You'll have to actually be braking harder than the engine.

In one of the chapters of Code's Twist of the Wrist he explains why not to use engine braking. I understand that it's harder on the engine.
I hardly used the brakes at all on the track or the street. After reading Twist, I've decided he's right: brakes are cheaper and easier to replace than engines.

I've never really understood the need for blipping the throttle the way he describes it; but surely there is something to it - at least in the faster/more powerful bikes.
