Downshifting & Throttle Blipping
Was having some difficulties with this a few days ago, but found this article that made it pretty easy to understand, as well as implement.
1. Downshifting smoothly on a sportbike, especially while braking hard from high speed, requires a definite measure of skill and dexterity. In order to avoid upsetting the bike, the engine rpm must be matched to road speed when the clutch is fully disengaged, otherwise the rear tire will momentarily "chatter" and upset the bike as the engine is forced to match road speed involuntarily. This means that the rider must "blip" the throttle to raise the engine rpm during downshifts-but he must do this while simultaneously pulling on the front brake lever to slow down. While this riding skill is obviously necessary on the racetrack, it can also pay big dividends in street-riding situations where riding smoothly is a must; for instance, any situation where you are cornering and braking at the same time. 2. The idea of blipping the throttle between downshifts can be intimidating for the uninitiated, but with a little practice, the technique can soon become second nature. First, make sure that your levers are adjusted so that they are comfortably in reach of your fingers when sitting in a normal riding position, and that your throttle is adjusted for minimal play in the cable. The front brake lever should be angled downward enough to be easily gripped with your hand in the closed throttle position. With the engine running in neutral, try blipping the throttle slightly while pulling firmly on the brake lever-note that it doesn't take much throttle movement to get the revs up. Then practice simultaneously pulling and releasing the clutch quickly when you blip the throttle (remembering to continue pulling on the brake lever as if you were slowing for a corner). 3. The next step is to practice this technique while riding in a safe area with no traffic. As you brake and begin your downshift, simply perform the same practice drill as before, but add the act of downshifting. The action of blipping the throttle and the downshift should be simultaneous and quick, and it doesn't take a whole lot of revs to match the engine to road speed; unless you're riding at racetrack aggression levels, all it will require is a slight throttle blip. With practice, you'll know just how much is necessary at various speeds. Note that mostly the palm of your hand handles the act of moving the throttle because your upper body weight is centered on your palms under braking anyway, and your fingers are busy actuating the brake and holding the bar. All it takes is a slight wrist movement to blip the throttle. You'll find this will help avoid affecting your braking action due to influencing your fingers' grip on the brake lever. 4. If you find that you still have problems with this technique, try adjusting your brake lever in so that it's easier to reach (without hindering your ability to pull the lever in for maximum braking, of course). If you still have trouble, you will have to employ the "non-blip" method many racers (such as AMA perennial front-runner Eric Bostrom) still use. This simply means the clutch is released gradually after the downshift so that the engine rpms can progressively match road speed without the rear wheel chattering. The downside is that the rider loses the added engine braking while the clutch is disengaged and the bike "freewheels," and he must compensate with the additional use of the brakes during this time. Also, it requires even more skill at manipulating and controlling the bike while simultaneously releasing the clutch lever slowly and gradually.

Good find!
Plenty of good advice you have; practice will make you master it. After that, you will do it without thinking about it.

So....when i downshift, at the same time, I also blip the throttle and then let go the clutch after. Am i doing it right?
(pull in clutch, downshift+blip, let go clutch) Plz correct if wrong. or is it engine braking? |

1) To keep the proper gear while slowing the bike down: Same process than shifting up while accelerating form a stop, but in reverse. 2) To keep the same speed of the bike or to accelerate, but having more torque on the rear wheel. Caveat: The rear tire may slid (which is bad in a turn) if downshifting without properly matching engine's rpm's and rear tire speed (correct procedure: clutch in + throttle off / throttle blip + downshift / clutch out + just enough throttle on to keep rear tire from locking up or skidding) Remember this: For up-shifting the engine's rpm need to slowdown a little between lower and higher gear. For down-shifting the engine's rpm need to increase a little between higher and lower gear.

It also help a lot if you use two fingers as opposed to your whole hand to brake whilst blipping...

My course taught it and we practiced it like one motion - that of wringing out a towel! Works like a charm. Your throttle wrist goes DOWN for shift DOWN and your wrist goes UP for shift UP. The clutch hand always finds the clutch whether you're 'wringing the towel' up or down. The foot will always find the shifter between clutch positions - just a great excuse to go out and practice. When things begin to click, you'll be smiling like a fool - it's awesome! My blips are still imperfect and will be for a while but hey, that's the best part of being a newbie - always more reasons to ride. |

I've been practicing my blips for all my downshifts for the past couple of weeks and have seen improvement. Although when I try to blip while on the front brake, I tend to inadvertently vary the pressure on the lever so the bike pogos a little.

You can practice the two motions independently too and once you're comfy with one or the other, THEN add the next step. For normal riding, you won't always need to blip to downshift because you'll be slowing down for a light or whatever already and you'll begin to hear when you are in the happy spot to downshift, those times all you need to do is lightly touch the shifter and it just plunks into gear like magic. That's clutchless downshifting and man, is it weird the first time you do that! Doesn't hurt the bike at all - I checked.. Remember you can't blip when you practice emergency braking, I once tried to do that.. stupid idea... No need to practice everything at once and remember that there are many bikers out there that never blip the throttle and they ride smooth as butter. Don't rush it. You have your whole life to have fun learning. Are you planning on going to the track at all? Most have brilliant beginner sessions that can help you fine tune things. Almost all of them have track days/instruction for total newbies. Sorry, I'm yappy tonight, was about to go for a ride when the rain came back hard :-( |

You can also start off practicing using the rear brakes. Once you get the idea move onto front brakes softly, then gradually harder.

what may happen if I use the rear brake at the same time with the front? I did a 2hr practice and used the rear brake with the front a few times but i pressed the rear lightly. I found that it felt smoother when i applied both brakes.
So far, it went smoother than when i didnt apply the ft brake or rear brake at all. Im beginning to understand why the ft brake is applied. Its fun also. I copied the video at 7:08. =D I choked a few times on the freeway ended up downshifting and not matching revs.Engine was revving crazy. =P My mind went blank. Im glad im on the 250. If i was on a bigger bike, I could have my first spill. |

I am not sure I would practice that on the freeway ijs...
Why the brakes are applied is rather simple. As K. Code states in TOTW2, "Brakes are cheap, engines are expensive". Or specifically, use the brakes (not the engine) to slow/stop and use the blipping technique to rev match your engine rpm to your rear wheel travel speed. Not only will it be smoother but you will already be in the proper and ready to get right back up to speed to stay with traffic flow. Be safe out there!

Lol. Yeah I've put like 500ish miles on the bike and have yet to get on the freeway.... granted its illegal here until u have ur license and I have my msf this week. But as far as the downshifting/blip thing it was sooo easy to do it once I just had a friend show me how to in person. Bike wasn't moving or anything but just showing me the motion made it so simple.. haven't had that nosedive feeling at all since then.

I wouldn't know . But it seem super easy on the 650. I've been using it to engine brake everytime I need to slow down now.. also that way if the light turns green while im slowing down or something I'm in the right gear to accelerate. Dunno how it could get any easier lol.

I've been blipping for almost 5,000 miles or more now and really have the hang of it. I've noticed the bike needs to ge to optimal temp before you can shift quickly. Having a race track for a county road also helps. It really prepares me a bit on how to prep for a corner or how to decelerate quickly. I wish I had a Gopro to show how I do it.

Most bigger cc bikes have slipper clutch. Probably the reason why some may think it's easy because slippers are more forgiving.

Don't think mine has a slipper clutch. Before the friend (actually just the mechanic I go to) showed me, when I used to try downshifting I didn't blip the throttle and so I would feel the nosedive and also locked the back tire once. It's just that everytime I downshift now I match revs, and that 'nosedive' is completely gone. Sometimes if I downshift a bit too early the bike will rev up just a bit but its hardly noticeable now.

Focus on keeping the braking constant while you blip. You'll notice your reaction is to hook on the brake lever and if you do, you'll see that the nose bobs up and down as you blip because you keep squeezing the brake and letting go. I'll see about getting some blipping video next time I'm home. I think my camera mount will work for that as long as I rotate the camera |

Tried to integrate braking with blipping today with no real noticeable improvement, still pogoing the bike even though I'm constantly trying to tell myself to keep consistent pressure on the brake lever.
I noticed that I was using primarily the palm of my hand closer to my index and middle fingers to blip so I would try to cock my wrist and crank it down in order to blip which probably influences my brake pressure lever. I'll make sure to try to grip the throttle with my ring and pinky finger to get a good blip. It seems that when I try to brake and blip, I'm overthinking and can't get a decent blip. |

Soon it'll become second nature.. Just keep practicing!
Also brake lever inconsistent pressure isn't the only reason why your bike pogo's, but also if you are over blipping. |

One of my problems is that I can barely get it to blip at all, it usually ends up with me cocking my wrist, getting a tiny/no blip and the bike nosediving from lack of revs and front brake.

Don't sweat it Richard. It comes in time, and it's not something one just magically does the 1st time out from watching a video or even 1 on 1 coaching. Keep practicing, it will become more of habit and embedded in muscle memory allowing your attention to be focused elsewhere.

Im catching on. idk how sensitive the bigger bikes brakes are but I feel like im getting the hang of it.
I Keep pressure on my ft brake (pointer and middle fingers), then I downshift and blip. Sometimes i pogo, does that mean i let the clutch out too late? or did I have a hint throttle applied? |
