When to Use Rear Brake Only?

The heavier the bike and the lower teh center of gravity, the more rear brake can be used. Also, with a passenger, more rear brakes can be used for smoother stopping and less front end dive.

A good rule... the engineers aren't stupid, the size fo the brake is a good indicator of how hard it should be used. I beleive the rear brake surface area is less than 20% of the total braking surface.

When do I use only rear brake. At low speeds when trying to reduce the effects drivetrash lash at small throttle positions. I also mostly rear brake at low speed turns where the front brake can be grabby causing a loss of balance. Finally on loose surfaces I will favor the rear. For one reason, the rear tire is wider and therefore easier to control when sliding that the narrower front wheel.

For emergency stopping (I hate the term "panic stop". You never, ever panic on 2 wheels.) ... it's ALL front brake. Engine braking provides plenty of rear braking force... especailly on my BMW twin.

Gee, I said as much and I was told I was an idiot. I'm not as good or as smart as Schwantz or Lawson, but I know that in any emergency situation the less you have to do, the better off you are. Front brake only and look for a way out. It served me well for 30+ years for road riding, so I guess my stupidity has somehow kept me alive for all these years. I guess since you think the same way, that makes you an idiot too. Too bad we all can't be as smart as the link posters on the site.
A man appeared before St. Peter at the pearly gates. "Have you ever done anything of particular merit?" St. Peter asked.

"Well, I can think of one thing," the man offered. "Once, on a trip to the Black Hills out in South Dakota, I came upon a gang of gnarly bikers who were threatening a young woman. I directed them to leave her alone, but they wouldn't listen. So, I approached the largest and most heavily-tattooed biker and smacked him on the head, kicked his bike over, ripped out his nose ring and threw it on the ground. I yelled, "Now, back off, biker s*****, or you'll answer to me!"

St. Peter was impressed. "When did this happen?"

"Just a couple minutes ago!"

Re: Braking 101.

but it worked on his bmx bike as a kid...
Seen in one of those Vee-Twin oriented magazines many years gone past:

Cartoon shows a guy in the E.R., bent over the exam table with a pistol protruding from his ass. Behind is the Doc, forceps clamped to the pistol and one foot pressed-against one of the guys "cheeks", pulling on the forceps for all he's worth.

Caption below it reads: "Last time it was a knife, time before that a baseball-bat! When are you gonna learn to leave those Hells Angels alone?"
Re: More braking tips

Weight transfer depends only on the deceleration rate and the height of the CG relative to the wheelbase.

The rear brake will not help you slow down any more quickly when the rear wheel is in the air - which is where it will be if you're doing a max stop on any modern sport bike.
It was a 12 guage not a broomstick :) It did the job.

Buz I thought you had forgotten I'm touched.
Re: More braking tips

dude I'm the one with the Engineering degree..not you...
I'll end it.

Ended what.. How many kids are going to die before we

1. get out of Iraq

2. ban handguns..

A shotgun is better weapon for home defense.

Thanks for your contribution to my kblog
Re: I'll end it.

Jeez, you fish and troll so much I'm going to call you Mrs. Paul from now on.

But what the hell - since backyard swimming pools kill 90 times as many kids as ALL guns do, I guess you favor banning those, too?
Re: I'll end it.

good night kzuki you're a good man.. 99% of what I say is BS.. Can't wait to read the new shoot out Buz is talking about ..
It's been said twenty times already but at slower speeds using a bit of rear brake in a tight turn will help calm down the bike's chassis and shocks from "jacking up" unexpectedly mid turn, and running past an apex. (and possibly continuing from there off the road into the trees) ...with rear brakes it definately helps to tighten up the line and let you carve through a corner much better than if you tried to muscle the bike through by simply coasting through the turn, or if you had just used the front brake.
If you've hung in there for 30+ years, you've obviously done a lot of things right no matter what anyone says. Motorcycle riding isn't necessarily black or white. There are all kinds of shades of grey. Once you have exposed yourself to as many options and techniques as possible, you can then determine what works best for you. Somebody else's right or wrong doesn't mean squat. Taking the time to decide which techniques work best for you and practicing them till they are instinctive and reactive are the keys to motorcycle survival on the street. But it sounds to me like you've already got that figured out.

I would, but it was sold already. I keep missing out on the good RD's. Maybe next time.

I yearn for a white open face helmet, clear motocross goggles and black leather jacket in the Loop at lunchtime, just to show off. The funny part is that I'm sure no one other than myself will be impressed. Ha!

Having walked past Physics class many times, I can tell with complete confidence that braking is highly overrated. Everything stops sooner or later. Even choppers.
The best way to make a tight U-turn is to do five things correctly at once: 1) Hang off the outside of the motorcycle. 2) Look as far as you can in the direction of the turn, completely over your shoulder if you can. 3) Hold a constant throtttle. 4) Keep the revs up by slipping the clutch. 5) Use only your rear brake to change speed while keeping the revs up and constant while slipping the clutch with a consistent amount of slippage. Be careful not to overrev the engine and let the clutch out too fast. You won't like the surprise in store for you.
The point to my previous post above is that it is the gyroscopic turning of the engine that creats the balance and stability to make a tight U-turn. That's why you have to keep the revs up by slipping the clutch.

John Wayne toilet paper at work? Sounds pretty camp. What is your "position"?

I liked the article #221. Especially the part where volts were equalled with torq. As you might know, in Europe we have 220 volts WHICH MEANS OUR HOUSES KICK AZZ HA HAA TAKE THAT YOU ****** BUZZARDS

Ok so its been a long laborous week.
