I would also say do not lean forward when braking...I think a lot of people naturally do this due to inertia and other factors but stay back and it will help with weight distribution.

ORIGINAL: Jump1979man smooth even controlled braking will not result in any lift of the rear tire.... I understand. What about in emergency situations? even in emergency situations you can still be smooth with braking....smooth braking can still be fast and quick... I have needed to mash on the brakes a few times and I have never raised the rear tire, although I have left a nice skid mark and fish tailed the rear a bit...its really hard to put into words typed on how to do it without sending the wrong impression as its hard to understand how you can be smooth and controlled yet still be fast and responsive... Ok. Fair enough.

Here's a great article: http://www.msgroup.org/tip.aspx?num=030 Another thing to remember when grabbing the front break is to let the chassis set before you squeeze hard. This will prevent wheel lock/jerky shock bounce. i.e. when you hit the brakes wait a fraction of a second to let the shocks compress and then increase pressure. Dont let the wheel get too high if it does come up... braking ability decreases as angle of the bike increases. Best is to lower center of gravity and move it back by body positioning, then brake. Just the opposite of preventing wheelies in hard acceleration

On a sportbike the front brake provides much more of the braking than the rear. Even skillfull application of the rear shortens the stopping distance by a small amount, and accident analysis shows the rear is usually locked, contributing to the accident. If you are seriously trying to slow down, dont even think about downshifting; even with a slipper clutch, rear slide is likely, and guaranteed if the rear brake is used. Pull the clutch in when you are hard on the brake!! The problem with the rear brake on sportbikes is that the rear tire contact patch decreases with increased braking force, you must decrease rear brake pressure as you get the suspension weighted forward or you will slide. As you slow, try to grip the tank with your knees instead of just leaning on the handlebars. This will keep some weight back towards the rear, you'll be able to squeeze the front brake harder without locking the front tire or bottoming the forks. Considering how hard it is to modulate the rear brake without skidding, it's understandable why many riders prefer to avoid it alltogather. Racers dragging the anchors as hard as they can usually just let the rear tire rise until it just skims along the road to provide directional stability, then back off the front brake when they start to lean. Stopping in a hurry and changing directions quickly are life saving skills every rider should practice

Or is the paragraph explaining such...Thanks for clarifying. And what are anchors? I like this input...it's got some meat on it. Thanks! There you go, after some input i have a different perspective on braking. Now, i just need some more practice.

Anchors=slang for braking really hard. As far as the the clutch and braking, downshifting and engine braking are fun and useful in many situations, but if maximal braking are the goal, ie panic stops and slowing for a 30 mph corner after a 130 mph straight, then you are going to pull in the clutch as you actuate the front brake. In a panic stop situation, you would keep the clutch in until stopped. If you need to turn instead of stopping, you kick the gearshift down to the appropriate gear, and, right before you lean in, blip the throttle to match revs, ease the clutch out, and ease off the brake.

+1 ampfp. I try to squeeze the brake slightly till the forks compress a little bit, then apply progressively more pressure on the brake lever. This stops you more quickly then squeezing hard the lever immediately and maybe locking the front wheel (think of an ABS system in your fingers). I learnt this the hard way . Grabbing the tank with your knees is also fundamental as it keeps in check your weight distribution. Engine braking does more harm than good; brake pads cost less than crank and locking the rear is nerve cracking to say the least. My .02.

Thanks for clarifying all that. Sorry, what does "blip" mean?

Pulling the brake is like pulling the trigger on a gun. Its a fast squeeze, not a pull, but a squeeze. It is something that pratice will help with. I am a new rider myself.. But I treat the brakes and clutch as a trigger.. All of my panic stops have been controlled and that is even with the rear brake. I have some nice open roads and parking lots where I live, so I go out and practice as much as possible.

There are so many opinions here, I don't know where to start. Sonomojay hit most of the points I was going to bring out, and I think you should listen (and so should some of the other posters who thought it was a good idea to talk about "what they do"). Some of you guys are going to get hurt with some of these dangerous philosophies. Remember to separate technique and philosophy and remember not to get too tied down to doing things one way every time. One thing I wanted to point out that Sonomojay mentioned is blipping and easing out the clutch...they are two different ways of achieving the same result. If you read Keith Code's articles on the skill of blipping he mentions that easing the clutch is a bad habit formed by those who never learned to blip properly and costs more attention and has other ill-effects. OTHERWISE- Keep reading, keep posting, and keep riding.
