I don't understand. If I work out to Km/h it's around 75 km/h braking down to 15k m/h in a time of 4 seconds when you started braking to catching up to car. Your bike should brake from 100 km/h down to 0 km/h in about 3-4 seconds max.

Hey man, I'm still new. At that time it seemed like a lot faster than I normally have to stop lol.

Do you brake mostly with your rear? I notice little, if any nose dive, and you seem to block the rear. You can't tell much from video footage of course and it depends how/where the cam is mounted, but if you do brake mostly with the rear, I suggest you reconsider quickly.
I do unfortunately. It's something I'm conscious of and work on. I remember when that happened thinking to myself "ok more front break." Idk why, but even during the multiple courses I've taken I'd always go heavy on that back break. I used to consistently lock up the rear from it during stopping drills.

Easy, don;t touch the rear brake, no need for it. All it's really good for is steering while leaned over or settling suspension perhaps before a tight turn. It's useless for slowing down a sport bike. The front wheel and brakes will grab hard enough to lift the rear wheel off the ground and with zero friction at the rear tire, the rear brakes become 100% useless. You could remove the rear brake lever and be perfectly fine riding all over

Agreed you need to break that habit. The front alone can bring a sportbike to a controlled stop quickly and safely when done correctly.

I rarely ever touch the rear brake, these are the 2 common situations I might use it:

- Taking off from a stop on a steep incline
- When I have a passenger with me the rear helps slow down the added weight, but still not really necessary

Another good reason to use the rear brake, is to reduce front dive. A fact, that the more physically minded might be interested in, is that nose dive is only partially caused by load transfer. Another reason, and about as important as far as the front brake is concerned, if I remember correctly, is that the braking force, being parallel to the ground, can be broken up in a component that is at right angles to the forks, thus bending them, and another that is parallel to them and points upwards. So the braking force from the front caliper, working with your rake actively compresses the forks.

Coupled with the fact that the rear brake tries to lower the rear (because the torque it applies to the wheel, countering its rotation, is reacted on the swingarm) this allows the chassis to lower more evenly, instead of nose-diving heavily. It's quite effective, especially on taller, heavier folks, such as myself.

Nevertheless, I agree with the idea of temporarily keeping your foot off the rear brake, to get used to braking with the front. Be sure to drive extra conservatively and defensively while you're doing so!

Adjust the rear brake pedal downward where your toe isn't resting on it or even near it . Make it as hard as possible for you to use as you can . If you have to brake aggressively you will be in trouble very quickly. If you use the front brake the way you should the back tire will barely be on the ground which makes the rear brake useless . and yes I know what they teach in the rider safety course's . What they teach works well for a normal bike . Sport bikes are a different animal .

Im one of the few people on this forum who believe the rear brake is effective in helping stop the bike quickly. I apply front brakes and rear brakes in a panic stop situation,majority of braking is done by the front but I will apply the rear brake accordingly,not just let my foot rest on the right peg if a car pulls out in front of me and not use the rear.

For street riding,my opinion still stands that the rear brake plays an important roll and proper use of it will benefit street riders.

That's certainly true, at least in principle, especially if you have the skill needed to initiate braking by relatively heavy rear brake and light front brake and progressively release pressure from the rear and increase up front.

I've always wonder though, if use of the rear brake in panic stops can actually cause problems for non-expert riders (such as myself): As you brake heavily and load trasfers to the front, the rear wheel is usually at limit braking if not blocked. This usually causes the chasis to weave slightly (or heavily in the blocked case) giving you the impression that the bike can't take much more braking and keeping you from applying more pressure on the front lever, although you could and probably should.

I've never really observed this on myself in an actual panic stop, as I've always managed to stop in time (except for one time, but then I certainly applied enough front brake, as the front wheel marginally locked). So perhaps I don't apply more pressure at the front, because I subconsciously know I don't need to, but I certainly do get that feeling described above sometimes and I wonder if it can be dangerous one day.

The main reason most experienced riders advocate that new riders not use the rear brake is due to the ease of locking it up, especially combined with heavy front brake use, which lifts the rear of the bike, making it even easier to lock up the rear. New(er) riders should learn to master the front brake first, and it's limits, before adding the rear brake to the equation.

However, I also believe the rear brake can be used for a number of things that will benefit an experienced rider, such as helping set/adjust your line mid-corner. I have been known to trail brake with the rear as well, depending on the corner. Using the rear brake while leaned over at speed is a skill that requires a great deal of practice (and crashes unfortunately) to get a good feel for it.

Yes,of course it takes a skilled rider to use the rear brake in an effective manner...it's just a routine function for me and after riding for so long,sometimes I forget Im even using it.
For beginning riders it can be a good way to low side and take a spill if they haven't practiced enough or haven't been taught how to use the rear properly

If you're on a big heavy hog or full dresser, the rear actually does have a lot of stopping power but almost diddly on a sportbike, except to more advanced riders who use it as has been described above.

Most of the time, I only use my front (street, not track). When it's raining, when I'm riding on dirt / gravel roads or those final, late-season rides up north when I get caught in a surprise snowstorm, I'll use my rear to share the workload with the front. Also, the rear is awesome to keep the bike from slipping backward when taking-off from a standstill up a steep hill.

As has also been said above, it can bite novice riders because it's just one of the controls that require finesse. While developing clutch, throttle and front brake finesse, best to leave the rear out of the equation until those other three are down to instinct / muscle memory.

You think that cuntknuckle(yup,directly stolen from cainyboy:biggrin)SoCalfuckface that was banned last night,used his rear brake whilst he was jumping his GSXR on the moto-x-track in those stellar vids he posted? :spit
 
#43 ·
Ask him to post the vid of him jumping his bike 2' off the ground on the dirt track,the vid where he is literally riding his bike in the dirt doing jumps and putting out his leg when he is turning like on a dirt bike...

I saw this one mentioned a few times, but I'd never use the rear in this situation. Why, because if you are in slow moving traffic the chances are you want to stop and put the bike into neutral and you can't operate the rear brake and the gears when you have a foot down. Instead I'd always use the front for his purpose, it works fine and means you have a foot for the gears.

It is good habit to leave the bike in gear when you stop. Cover the rear brake to prevent rolling backwards, and modulate the throttle/clutch as you would normally.

It's hard to tell from the video, but there was definitely no partial pullout. He went for that shit without touching the brakes until he was already in my lane lol. That's why I couldn't believe it. The fact he didn't even try to stop until he was in the road. If he would have hit his gas though instead of the brakes that would have been "normal" for Guam. Anytime you're on the street you see someone pull up to an intersection like that and just go without ever taking their foot off the gas. It's crazy to see. I didn't go around to the left for two reasons. 1) That tuck I passed was somewhere just behind me. I hadn't gone very far past him and decided to focus on braking rather than looking to see where he was. 2) Trying to go around someone without braking is how I got into my first and only accident. 17/18 years old, coming back from work at McDonald's, and actually doing the speed limit for once, I had a car making a right on red who decided to just turn without stopping and he turned all the way in to the left lane (your supposed to turn into the closest lane to you) which was the lane I was in. He cut me off much worse than this guy, and while I could have slammed on my brakes, I decided to change lanes and go around him. Well he realized last second how bad he cut me off and also went to go change lanes to the right (yes he basically cut me off twice now lol). At that point it was too late. I made the sharpest turn I could to go back to the left, but my front passenger side bumper hit his rear driver side bumper. I learned then to just do the wise thing and brake lol. On top of that, I didn't want to go around the front of his car when he decides to pull another dumb move and hit the gas again.

Clearly you made a good choice as you avoided an accident, that's the most important thing.

That said, it seems like you are thinking like a car driver not a motorcyclist.

If there are two lanes of traffic then on a motorbike there is also a gap between the two lanes which you can almost always use [big trucks aside]f. If you ride in the primary position which is around the same location where a car tyre would be, on the side nearest to the other lane then you always have options. You can brake (as you did), you can change lane (small movement left or right) or you can drive between the two lanes.

What if you couldn't stop in time, you would have had loads of space to go around the car without having to move into another lane of traffic if you just went down the middle. Of course there a risk the driver also changes lane but it's rare people pull out across two lanes at once.

Splitting lanes is illegal here in the US aside from California.

Even I know you shouldn't go to neutral while at a stoplight lol. Besides what Anthony said about having to leave in a hurry, I was also taught that if you were actually hit you want your bike in gear so as soon as you release your clutch (most likely from being thrown onto the cars hood during impact) the bike shuts down immediately rather than staying on.

While searching his youtube channel for that video, I saw that his (I assume it's him) gsx-r has a studded knobby on the rear :suicide

After spending time on gsxr.com, I took a shower and am back. I signed up over there same time as here (2011) and after my 2 posts yesterday, my post-count is now up to 3 :lol

More photos of Guam driving. If the guy in the first photo stopped any further in the intersection he would've been on the other side and in the second I passed a sign saying "left lane closed" but then had to merge left lol.
