Emergency breaking - How not lock up the rear?

I found the easiest way to control your foot is to squeeze your knees against the gas tank. It took 4 or 5 runs but I haven't locked up since.

Great tip! Im going to give it a go.

My first real and real life threat panic stop was last summer it was a normal summer day riding the scenic mountain road to Whilstler with the wind flying through my long wavy blonde hair(that part is a blatent lie ),I switched lanes , the road was dry and flat heading too fast towards a row of sudden stopped cagers. Now was sweating bullets and inhaling car fumes thinking who is going to take care of my only surviver cat Harvey ,I don't have much motorcycle trainning or experience at spelling.
I nearly maxed out both brakes making sure was on a very straight bike :) pumped both of them on /off thinking this may stop a sudden PNE rear lock slide tumbling down the scenic mountainside but I don't think would have time to take in the views...not sure if that is bad don't know much about brakes yet but here to post about it,
would of done a flying trapeze act maybe 9 out 10 points if was a sanctioned CMA Olympic or YouTube event over the car a few yards away from me if not stopped fast.. this was on a typical cough cough err Sportster model. Anyone in a panic stop likely recalls how you focus and time seems in slow motion even if it's a Harley :)

Aside from heading to a parking lot or an abandoned road and letting'er rip, what tips do you guys have?

Ive had to hit the brakes pretty hard a couple times from 80ish kph on my non-ABS Duke (which has amazing brakes). I seem to be better with the front than the rear, but the rear (and possibly the front) is locking up, squeeling a bit and has gotten a bit sideways on me. No biggie, I can countersteer it and keep the bike under control even though the body of the bike is pointed in a different place than the wheel. Sounds worse than it is, but it doesnt bother me.

But Id like to learn how to modulate the rear brake better. I have decent feel in my commuter footwear but not good feel at all with my A* boots on. I lock the rear up with either.

Any tips beyond telling me to be on/off the brake as needed? Im not sure I want to be off it for any amount of time if I NEED to stop. How did you guys master this?

I guess that is the heart of it - the unweighted rear makes it close to useless in threshold situations.

So riding around normally, its useful. Grab a handful of front brake and there is no weight on the rear anyways. So its not going to help.

Try to progressively squeeze your brakes rather than hitting them hard or grabbing a handful.

ummm... I thought engine braking at the track is a nono...gotta be in the right gear all the time...engine braking = lost time, no?

Incorrect


I removed almost all of my engine braking, so that my sloppy mid corner throttle control doesn't upset the bike at all :) Lots of track guys ask me to take out anywhere between 50% and 70% of the engine braking. On an R6 or R1, especially when geared aggressively, the stock engine braking is absolutely insane. In stock form the bike completely turns the engine off on deceleration (by cutting the fuel injectors), which leans the engine right out so when you go to go back on the gas even just a hair of throttle causes a snap/twitch.

...then I need a track day to find out if this is true as I always thought engine braking leads to violent speed scrubbing -a thing to avoid..rather than this - to brake and downshift to correct gear ...

...need to learn more!!!
 
Could you explain the physics of this?

All I'm going to say is the front brake transfers your weight to the front more than the rear brake. If you're manoeuvring the parking lot doing your M2 exit and you're not using your rear brake you're doing it wrong.

For daily street riding is it ok to apply both brakes most of time so as to get some memory muscle , I know the basics of front brakeing the front wheel should be straight or will
get pulled down like a magnet, thanks

It seems like a complicated subject for me anyway.. but knock on wood have not locked for awhile, last time was an over reaction when a jerk cager darted out of a Gas
station and cut over 2 lanes in front of me, had a rear lock but was ok.

Using both of your brakes is perfectly fine, I did it all the time on the street. You can use your front brake in a corner but you have to be extremely gentle and this is a more advanced skill. On a longer sweeping high speed corner it will actually try and stand the bike upright when you apply the front brake. If you apply too much you'll end up with a face full of asphalt. Entering a corner while applying the front brake is what's known as "trail braking" and trying to do this on the road with less than ideal conditions could result in a lowside.

Putting some thoughts into theoretically answering the question:


As was mentioned, squeeze your knees against the tank.
With the leverage of the tank, use your core muscles to focus your weight down and back into the seat, and your upper leg muscles to force your heels into the foot peg.
NOTE: do not use your arms to push your weight down and back (they have to control steering and braking).
Lock your legs in this position, and use only your lower leg muscles to modulate the ball of your foot against the brake lever.
In a quick, but smooth, progression, squeeze your calves with enough force to induce a "gentle" lockup.
Once it locks, come off the pedal in millimeter increments until the sound is just above a whisper.
As the weight of the bike transfers forward and you progressively squeeze the front brakes, continue to come off the rear brake and maintain that just louder than whisper squeal.


Feel free to pick apart the theory.
Obviously in practice, this is all just a blur of info.
I've been able to pick out the individual parts at different times though.
