Blipping the throttle

Can you guys please explain blipping the throttle? What is the correct way to do it? I'm just curious because at the track I could sometimes hear some of the guys doing it but I never do it. When I'm braking hard and I downshift, I try to do it smoothly and slowly and gradually release the clutch. So far I haven't upset the rear(suspension or wheel) and I can do this method smoothly. I want to get into the habit of blipping the throttle but I'm just curious, do any of the fast guys ride without blipping the throttle?

The fast guys that do it and don't blip the throttle or don't do it as much most likely have a slipper clutch.

The guys (like me) who don't have a slipper blip the throttle or in other words, rev match, so the rear wheel doesn't lock up or chirp during downshifts. You want to decelerate and get into the brakes as smooth as possible, the smoother the better to not upset the suspension of the motorcycle or lock up the rear.

Everyone will explain it a bit differently and do it a little differently and its a bit hard to explain online typing.

Sometimes I grab downshifts and brake at the same time. To do this you need to have your index finger and middle finger on the brake and your ring finger and pinky finger remain on the throttle to still have grip. Pull in the clutch, grab your downshift and blip the throttle (to a certain rev matching RPM to keep the revs high enough) almost immediately after/during releasing the clutch. The whole process is almost one motion. It is done by feel and hearing the motor of the motorcycle.

If you are decelerating/braking at an extremely fast rate (on the binders hard) you are going to have to perform this process at a very fast rate.

Thats the best I can do without talking to you in person.

yes some fast people (factory riders) use the method you are currently using but many people also prefer to blip the throttle, so your current method is not necessarily wrong but you probably want to try the method of bliping and see what you like better, and grasshopper has good info up already on how to

I blip the throttle on everything (Buell when I had it, my street car, even my fiddy)... It's an old habit from when I tracked my car.

In a car it's known as heal-to-toe braking. Basically it's using the throttle (while on the clutch) to raise the RPMs to the point where they would be in the new gear so the there is no extra deceleration caused by the clutch being let out slowly and having to pull the RPMs up to the correct level.

If you want to feel the difference try it without the brakes. Get all the way off the throttle, pull the clutch, let the revs drop down to idle, down-shift, and ease off the clutch. Then try it but instead of letting the revs drop down to idle use the throttle to bring them up to where they would be.

The reasoning behind blipping is that if you are braking hard (using nearly 100% of your traction circle) adding in that extra clutch-braking (not to be confused with engine-braking) will push you out of the circle and you'll be sliding.

edit: From what I understand slipper clutches are designed so you do not need to blip because they will slip (like you're riding the clutch) if the clutch-braking would be too much for the traction circle. I could be wrong and I'm sure someone who knows better will correct me if I am.

The best way to learn to blip is to start by doing just that without
the added complication of braking while blipping.

While riding along in a comfortable gear, blip a downshift.
The blip only needs to be 500-1000 RPM...not half the tach.
When you get it right....you feel nothing.....that's right....nothing.

Too many revs and you get a bump of acceleration when the clutch
comes back out. Too few revs and the bike slows down and you feel
a braking effect from the motor.

Just right and YiiiiinGAH you are in the next lower gear, felt nothing
and are now cruising along at a slightly higher RPM.


Upshift, repeat ...... again and again till it's smooth.



When you start to do this while braking the HARD part is not bouncing
on and off the brakes when you blip. SOme people use their index and middle
fingers on the brake and blip with their thumb and two little fingers. Others
keep their thumb and index on the throttle and use the other three fingers
for braking..... you have to decide what works best for you.


On the street, I use my index finger for braking and the rest for blipping.
On the track, about the same ocasionally adding the middle finger to the
brake.


Even if you have a slipper clutch, this is a technique worth learning.

I'm not fast, but I always do it.

RWS is right, get in the habit of matching revs on the street too. That will help make it a habit. If you're riding in the wet or other slick surfaces it's a good habit to have. Helps reduce clutch & rear tire wear too

Absolutely... I raced and abused my Del Sol up to the point when I sold it with the stock clutch still holding perfect at 140k.

this is something I also want to work on this coming track season. I have the concept down in my mind, but like moparboy said, i think it will be difficult do at first, mostly because it has to be done so quickly while still being smooth. I didnt do this at my first trackday at heartland and i noticed that i was getting a little wheel hop coming into corners. i figure that as i get faster this will only become worse. i might as well get into the habit of blipping now so i dont end up paying for it down the road.

Cool, I haven't been doing this on the bike, but I've been doing this in my car without realizing it. I started to add a little throttle because the car would jerk or shift hard in down shifts. I started doing that and downshifts are a lot smoother now. I guess on the gixxer I haven't had to brake hard enough on the street to have to do this.

I suck at it on the track. I find it hard to brake hard and rotate that damn throttle. Slipper clutches are the way to go. So I hear. I usually try to get the revs close and let the clutch out slowly. But when I get it wrong.... It's a whole lot of fun watching me slide all over, just ask Jkrueger.

I need to work on this as well. On the street I can match revs fine, (when I'm not in a super hurry).....but I have problems doing it smoothly when I'm booking

Do you still feather the clutch out, or do you just dump it like you would on a fast upshift?

Thanks man, that was very helpful

Thanks for all the replies guys. I'm gonna get in the habit of doing it all the time. One thing I realized is that I sometimes do blip the throttle without really thinking about it. I know for sure that I don't do it all the time though, specially at the track. Thanks once again fellas.

The faster you ride, the slower your inputs.


Never Ever dump, slam, slap, cram, flick or stick anything !

And if you *can* dump, slam, slap, cram, flick or stick it you are NOT
going as fast as you could if you were smoother.


Mind you this is more about ROADRACING than DRAGRACING.


By the way ...... you only need about 1/2 a clutch stroke for a downshift !

SO slow down your entry...... get your braking and blipping done.
As you perfect the skill .... slide the markers upa gain a little
at the time.

Pretty soon ........it's whap whap whap....turn.

I've tried without it. Just doesn't feel natural to me and I don't see a reason not to use the clutch, so it's a habit I really haven't tried to break

It's an easily broken habit. If I ever feel the need to break it, I will.

the same time you are braking and the clutch is in, you just blip the throttle

that is how you blip the throttle

From my car experience truer words have never been spoken. I found that the more relaxed I made myself the smoother everything was, the faster I was. As weird as it may sound, I found that breathing exercises helped a lot to stay calm and fluid.

Oh yeah .... breathing...... it's funny how many people concentrate
so hard on their riding that they forget and hold their breath.
