The physics of braking on a motorcycle (manual transmission)

In summary, the question is whether engine braking can have a negative effect on the rate of deceleration when trying to abruptly stop a motorcycle. The fact is that front brakes are most effective in slowing down a motorcycle, but engine braking can also be effective, although not as much as front brakes. In a scenario where the maximum front brakes slow the bike down at a rate of X and the engine braking slows it down at a rate of Y, it is possible that Y may have a negative impact on X and therefore, using only front brakes may stop the bike faster. However, in a theoretical straight line scenario, it is likely that using both front and rear brakes while leaving the engine in gear would be the most effective way to stop the

When trying to abruptly stop a motorcycle that is in motion, can engine braking actually have a negative effect on the rate of deceleration?

Scenario: a motorcycle is traveling down a straight highway at 100mph in 6th gear and needs to perform an emergency stop. The weather is clear and road conditions are perfect (i.e. no oil or debris on the road).

Question: will the bike stop faster if the rider pulls the clutch in AND engages the front brake? OR will the bike stop faster if the rider only engages the front brake?
(We'll say that the motorcycle's speed in 6th gear while the engine is idling is 15mph so, for the purposes of this scenario, we will consider 15mph as "stopped" because below that speed the idling will certainly produce forward force)

Fact: front brakes are most effective in slowing down a motorcycle due to weight transfer to the front wheel.
Engine braking is also effective but the force is exerted on the rear wheel only and the rate of deceleration provided is not nearly as high.

So, let's say maximum front brakes slow the motorcycle down at a rate of X.
And let's say engine braking slows the motorcycle at a rate of Y.
X > Y

So, is it possible that Y has a 'negative' impact on X and, therefore, the bike would actually stop in a shorter distance if the rider clutches IN and only uses front brakes? Or will Y (engine braking rate of deceleration) always provide additional deceleration (in 6th gear which at lower speeds does not provide a large rate of deceleration) and actually has a 'positive' impact on X and therefore will always stop the bike in a shorter distance when using both front brakes and engine braking ?

Someone please enlighten me. Initially, I thought engine braking *could* have a negative impact the rate of deceleration of the bike under heavy braking (using front brakes) but now I'm not so sure

Also please consider the difference characteristics of a sport bike vs a cruiser if that has any bearing on the response.

Thanks!

EDIT: Perhaps a better fitting scenario is:
2 riders on identical bikes accelerate to redline in 3rd gear, hold redline for 3 seconds, then perform heavy braking. Rider 1 clutches in and only uses front and rear brakes. Rider 2 leaves 3rd gear engaged and uses front and rear brakes. Assuming there is no skidding or loss of road contact with the rear tires, who stops faster?
(If it's not clear, basically, I'm trying to determine, from a physics standpoint, if adding "engine braking" can actually cause a bike to take longer to stop in certain circumstances. i.e. when braking force (from use of front and rear brakes) is greater than engine braking force. Because, of course, if a rider is only applying a little bit of brakes, engine braking will *assist* in slowing down the bike)

here's my thoughts -- shoot at them
(not a racer, just a slow cruiser -- but still very happy with ABS)

Use both brakes -- the front does the work, the rear keeps the rest of the bike from overtaking the front in some uncontrolled way.

So in that line not engaging the clutch is better.

And now for the theoretical case: assume a straight line no matter what. Front brake does the work -- can't be too much or you still go over forward. Any rear wheel normal force that's possibly left over can contribute to braking force. If nothing is left over it doesn't matter if you engage the clutch or not.

I thought that maybe, because the deceleration rate using engine braking was less than using brakes alone, engine braking might (in some scenarios) have a negative impact of the total deceleration rate. But when I think about it now, it seems like it would only help deceleration.

Say it takes 15 seconds to decelerate from 10,000rpm (120km/hr) to 2,000rpm (30km/hr) using only engine braking.
Say it takes 7 seconds to decelerate from 120km/hr to 30km/hr clutching in and only using the front and rear brakes
I don't think leaving it in gear and using the brakes will shorten the 7 seconds, I hypothesized that it will take 9 or 10 seconds to slow from 120 to 30 using front+rear brakes with the engine left in gear. But my bike has a "ride by wire" throttle system (electronic signal, no physical cable) so it's possible that the bike's electronics could be affecting the deceleration by giving some throttle when I have not twisted the throttle.

I could, and probably will, try to test this theory once I insure my bike in about a month but think that my braking will likely not be uniform and so the results of the field experiment will not be, for lack of a better word, valid. My experience/feeling thus far makes me believe that engine braking *can* have a negative effect on total deceleration rate but am looking for someone with a specialty in physics to correct me and say that engines with no throttle engaged will undoubtedly assist in slowing down the motorcycle at any given speed/rpm.

I have one of these (same color too :cool: ) and I wouldn't dream of trying to test its braking to any limit whatsoever. 30 m at 60 mph means learning to jump off is more effective than learning how to brake 1 or 2 m less.
And if you're a beginner you shouldn't try it either. Certainly not at 100 mph. Establish a comfort zone and stay in there.

If it takes you any time at all to 1. Start considering how you should best be stopping or 2. Introduce any possible delay in applying the brakes then your effective 'thinking time' will increase. This involves traveling at maximum speed for whatever small length of time you have wasted. Being in neutral during the stopping process means you have fewer options, if circumstances should change during the process. That could be bad news.
The initial effect of braking by the engine will be the greatest because the internal friction / loss mechanisms are maximum at high revs.
I can't think of any reason for emergency braking in neutral - except for the possibility of the wheels being driven after you have possibly come off the bike. That could be bad, too. I have seen videos of rogue bikes getting up to all sorts of antics when the rider has come off. (There should be a return spring on the throttle, in most cases.)

- the limit on how fast you can decelerate is dependent on the tire since brakes are powerful enough to lock the wheel.
- the bike slows down whenever the wheel is experiencing braking, this can be from engine braking or regular brakes.
- modern brakes are powerful enough to lock the wheels, thus the need for ABS to keep the wheels spinning and not sliding.
- engine braking works because throttle body closes and creates vacuum in the intake stroke which resists the engine spin.
- engine braking always helps normal braking. But that doesn't mean you stop quicker, it just saves your brake's wear.
- in op's example, the two bikes stops at the same time because the brakes are good enough to provide braking force to the wheel regardless of engine braking, and it is up to the best tire to deliver the stopping force to the moving bike.

On a sportbike or a superbike, full braking with the front wheel is enough to lift the back tire off the pavement. It is common at the racetrack (I ride track days) for the back end to be "skipping" off the pavement as you are braking hard for a corner. It's a little un-nerving at first, but you get used to it and it helps you to "feel" when you are at max braking. Any less and the back tire is not skipping, any more and you are lifting the back end too much and need to ease up a bit to get it back near the ground.

The technique that is taught at racetrack schools is to downshift through the gears while using max front brake. You need to either blip the throttle at each downshift to get the revs to match the wheel speed in the lower gear, or you need to learn to ease the clutch out on each downshift to let the tire spin up the engine smoothly to the matching RPM for that gear at that speed. If you do neither, then the back tire skids as you let out the clutch at each downshift, which can be very distracting if it gets you sideways as you are braking into a turn. Do not ask me how I know this so well...

You can try to use the rear brake under hard braking on a sportbike, but again you risk skidding or worse yet stalling the engine if your rear tire is off the ground and you tap the rear brake. It's usually safer to use engine braking for the rear, since it is skipping off the ground anyway.

And learning and practicing full-on braking at a racetrack is the best way to learn the techniques. I have had to use full-on emergency braking a few times in my street riding, and knowing how my bikes act at the racetrack has helped to save me several times on the street.

Ride safe!

If the front wheel has enough grip to allow the rear to liftoff the ground then engine braking can't contribute.

If the front wheel didn't have enough grip to do that then yes any braking force the rear wheel can provide will help (be it engine or rear brake).

These are all good replies and I appreciate the time spent.
There was the assumption that there is no skidding or loss of contact with the road of the rear tire so these scenarios aren't necessarily maximum emergency stopping which could result in skidding or loss of contact; these scenarios are *heavy braking*
The idea is, under heavy braking (using front and rear brakes), can the engine winding down (causing "engine braking") be at such a lower rate than the heavy braking force that it could actually hinder the deceleration of the bike produced by the front and rear brakes alone.

Originally, I had thought engine braking Could hinder deceleration in certain scenarios but after more consideration I think it's likely that the deceleration force produced by the "engine braking" can only help to decelerate the bike (and not, in a way, work against the brakes)

This idea is correct. If you apply both brakes then it's always better to decouple the engine, so you don't have to brake the engine, just the bike (less energy to dissipate by the brakes).

But the original question was about using front brake only, with or without clutch:

This is one is tricky, because it depends how fast the engine slows down due to internal friction, compared to the front brake slowing down the entire bike.

Yeah, what I went looking for was a CLASS video that demonstrated engine braking (via the engine sounds), but that was the first video in his list, and I gave into temptation. The music makes it hard to hear the engine sounds, but it's still a great video of my favorite racetrack. Riding down the corkscrew at speed is incredible.

So here's a more on-topic video that demonstrates how engine braking is used for high-performance riding. The music goes away after about 30 seconds, and you can hear Reg's engine very well... :smile:

One issue is that applying the front brake can reduce the normal force on the rear tire to cause the rear tire to hop, chatter, or skid due to engine braking. Some sport type motorcycles (and most racing motorcycles) have a (one way) slipper clutch that limits the amount of engine braking. Wiki article:

With regard to your first statement; having to brake the engine; what laws of physics, more specifically 'forces', would be propelling the engine 'forward' that would require the brakes to have to displace that energy too? Once the throttle is released, does the engine start and continue to slow down to idle RPM?
My initial thought was that there is a certain rate that the engine "winds down", and if you are braking hard and slowing down the bike at a greater rate than that, yes, the brakes would have to slow the engine down further as well.
However, what I'm unsure about is if the engine "winding down" is always going to be at a rate faster than what the brakes are doing, hence the whole purpose of this post.

I've posted this question on a Facebook Motorcycle group and many who chimed in (supposedly skilled and even some so-called instructors) believe the engine engine braking will always further assist the brakes in slowing down the bike... but I'm very unsure and wanted to pose the question to more physics-minded people, not know-it-all so-called skilled instructors :)

Nothing is propelling the engine, but it has rotational kinetic energy, which needs to be dissipated too, if it's not decoupled.

For normal brake application, engine braking would reduce some of the wear on the brakes. For near maximum braking, where there's very little normal force on the rear tire, engine braking can hop, chatter, or skid, which is why "slipper" clutches are used on race bikes and some sport bikes. See post #16.

So as the op asked the question the simple answer is no
The long anser
The engine brake is inversely proportional to the effect of the front brake
but never reaches negative effect as long as road speed is in excess of RPM

As soon as the throttle position goes to zero, the butterfly valve is closed and the engine gives braking. With fuel injection, no fuel is injected at all. I'm assuming petrol and not diesel for a motorbike.

Unless it's a bike like mine with a carb that idles a little rich
The ratio selection is governed by wheel speed and never in neutral at speeds above 15 mph or 25 kph so engine braking is automatic that's why I added a small manual EGR throttle so I can coast farther and save a sip of gas

But I guess most of the fuel will be unburnt and you won't get much, if any, drive(?) because the mixture with loads of depression will be far too weak. (Unlike a diesel engine in which even a dribble of fuel on the overrun will still ignite.
But we are dealing with minuscule amounts of power compared with what the brake pads will be dissipation (many tens of kW)

Four of my five bikes run carburetors, and the oldest of the bunch has a manual advance points ignition. The black lever on the side of the tank is the shift lever. The clutch is foot-operated.
Extra low-tech -- 45 c.i. flathead engine, pulling maybe 20 HP. No suspension in the rear, and only about 2" of travel in the front forks. The seat has about 4" of travel though, so it absorbs a lot of the bumps in the road. 1946 Harley-Davidson WL, very similar to the many thousands that were produced during WW II.

Thanks! My other old one is almost as old, and similar in style, but slightly newer technology - OHV 74 c.i. engine, and running an electronic ignition. It's still manual advance though, via a throttle-like control in the left handgrip.
With regard to other comments in this thread, there's no chance of the rear wheel coming off the ground when the front brake is applied with either of these bikes.

The greatest chance of a negative effect of the engine, is if the rate at which the engine will slow down when the throttle is closed is slower than the rate at which the front brake will slow the bike.
eg: if the engine alone (no gear selected - on the stand even) drops from 6000rpm to 2000 rpm in 3 seconds when the throttle is closed, and those rpm figures correspond to 90 mph and 30 mph you need to ask - could the brakes slow the bike from 90mph to 30mph in less than 3 seconds. If the brakes can, then you should de-clutch.
From what I hear/observe, engines on sport bikes are very responsive - when the throttle is blipped the revs rise and fall very quickly. For a cruising bike, that rev change is much slower (perhaps cruisers just don't blip the throttle much while waiting at the traffic lights). Thus you may be better to de-clutch a cruising bike - but use both front and rear brakes.

It's funny someone posted a video of Reg Pridmore and y'all still missed the interesting physics :)

There's actually a bunch of physics at work with the rear brake and suspension.

Pridmore used to ride BMWs, back in the days when they exhibited a wonderful habit called "jacking" where the rear end would actually rise up when you hit the gas and the ring gear tried to climb the pinion.

So shaft vs. chain if you're trying to do all the physics, and you need to include feedback mechanisms like chain snatch and gear lash.

Second is the effect of the rear brake and the engine and chain/driveshaft on the swing arm. You're changing frame geometry, which is going to change the tendency of the bike to lift or squat, which changes braking efficiency.

I'm not a physics weenie, I just have a lot of experience on bikes. Picture a rhomboid with a hing in the middle sliding on a plane and the non-parallel sides made squishy. That's the front forks and the swing arm. (I'm ignoring BMW's telelever suspension, as well as the imbecilic no rear suspension configuration) Intuitively It seems like you're going to maximize the braking if you drive both front and rear suspension down at the same rate initially. You're accelerating the whole thing towards the ground, you're going to maximize friction.

Is that very slightly more true for spoked wheels than mags. Spoked wheels deform so you probably lengthen the tire contact patch by what? Thouandths of an inch? Or is the wheel shape overshadowed by the tire deforming? Not sure there.

If you hit both brakes and initiate that dive towards the ground, the momentum is going to try and tip the rhomboid on its leading edge.

If the front wheel does cause the rear to lift a bit and the rear brake isn't applied, it's not going to do much when it makes contact with the road again - however if you have the rear brake on while its in the air, it's going to try to accelerate the swing arm towards the ground and make contact sooner than it would if you weren't on the brake.

In other words it's not a one-time weight transfer/change in momentum, you've got a wobbly jello thing at work as bits of energy are dissipated in different places and those places change over time.

In the old days of dirt bikes we used different riding techniques for full-floating rear brakes vs. non-floating ones. By dragging the brake pedal even with the throttle on you could get the rear suspension to compress partway, which would actually make you faster through the whoopdies. It kept the rear wheel in contact with the ground longer by preventing the springs from extending all the way, so it didn't try to do a little launch at the top of each bump. By changing geometry, you could go faster with the brake on than you could with it off.

There's another trick that may or may not work with modern street bikes (probably not with a steering damper) Just wiggle the front wheel a bit. Setting up a side-to-side motion can improving the braking. It definitely does with dirt bikes in mud, it forces the knobs to make contact with the sides of the tire as well as the center.

Now to really mess things up, consider the physics of single-sided vs. double sided swing arms

MIT Physics Demo -- Bicycle Wheel Gyroscope



:)

I'm a fan of physics, mainly because it shows up like the Spanish Inquisition, when you least expect it.

I was riding my R1150GSA in MT during the spring and got caught in a very heavy slush/snow squall. I was approaching a steep uphill with curves and I wanted to make sure while I was still getting reasonable traction because there was a solid 3-4" of snow and slush on the road, so I goosed the throttle a tiny bit to see if I could break the rear loose at all. It did, just a little. So I went back to a neutral throttle so I wouldn't slide. It returned...and then the wheel/driveshaft fed back and it started to go a little to the side...and back...and to the side...and back...and... It actually set up very slowly oscillating feedback loop that caused it to go sideways harder and harder, eventually (after ~0.1 miles) resulting in me sliding down the road and a very long way through the grass on the side of the road. No throttle, no brakes, just drive line slack and wheel rotation and rear suspension combining to put me on my butt.

Oh, and the short answer? Sorta like the value of helmets, don't ask physics weenies, ask the Moto GP guys. If there's a way of stopping faster on pavement, they'll know it and probably have tried every other combination before settling on it.

Never been on a modern sport bike but personally I'd used both brakes, scoot my butt as far back as I could, sit up tall and put my knees out to catch as much wind as possible. Every little bit helps in a panic stop.

Complete analysis of this is not simple. A simpler model is of braking a train. Application of engine braking and load car braking increases the heat dissipation of the overall system compared to disengagement of the engine and using engine car wheel brakes alone and results in shorter stopping distance. Formula I racing makes extensive use of engine braking. That's the purpose of heel & toe and double declutching.

Motorcycles require techniques that trains and cars do not require, and modern bikes and most race cars make use of a synchromesh, which means single declutching is sufficient, but a skilled rider can brake faster if he uses engine braking and rear wheel braking along with front wheel braking than he can with front wheel braking alone, including into a turn.
