Why do they do that?

I have a rather dumb qestion...

I was watching superbike racing and I notice that before they get to the turn they turn their wrists on the throttle on and off as if they were reving up or something... why do they do that? and what is the purpose of it???

Good question Max...

I also observed this technique ever since I started watching WSK and AMA races. I believe what the rider is doing is blipping the throttle during each downshift before entering the turn. I am almost sure of this but please correct me if I am wrong.

Thats correct,that is why they downshift so smooth

downshifting so fast would lock up the rear wheel if you didn't blip the throttle. The trick is to be able to blip the throttle and apply sufficient force to the front brake lever at the same time.

:thumbup Same techinic they use for RACE CAR i.e.Street Race.If you notice on Grand Tourismo on PS1 and 2 if you use mannual gear it will REV up before down shift. The purpose is to make sure the bike is in the HIGH REV to prevent the RPM from dropping too much. :fact

But I though everyone blip their throttle when they downshift, right? Just wondering, if not, then how do you guys do it? Just release the clutch slowly? Just wanted to know how some of you guys do it, me I blip the throttle.

Not really. Blipping the throttle while the car is between gears will match the engine speed to the transmission speed. This will allow a smooth downshift that does not unsettle the traction balance. This blipping also allows clutchless downshifting in bikes and cars.

I would guess the WSB guys are not screwing around with clutching through the gears. If they use the same technique as cars, is just a blip and a shift.

mick doohan also used to blip the throttle mid corner to clear the engine so it would pick up more cleanly on the exit, dont quite know how but its from his lips that i heard it.

i blip the throttle on downshifts if im scratchin' so as not to lock up the back wheel, but if im just cruising to work or something i just knock it down a gear, theres no problem with the back end 'cos im only doing low revs.i use the clutch on all my downshifts though, whether they are at slow or fast speeds.

i used to find when i first started blipping it on downshifts that i used to 'snatch' the brake each time i revved, but the more i did it the better i got until i could do it smoothly whilst still braking hard.

I have been "blipping" my bikes for years... but in those years, braking technology has advanced significantly. The 2-finger binders they have on my new R1 are light-years ahead of my 91 FZR1Ks--and those were among the best in 'the day." Because of this, I read in the latest Motorcyclist that "blipping" in racing is rapidly becoming superflous--that the extreme braking the new bikes are capable of are evening out the difference tranny/engine speed, so all you have to do is feather out the clutch, and it won't lock the rear wheel. Of course, that's just what they say in the motorcycle mag, and only applies to situations where you are diving into the corner and braking super late and ultra hard. Haven't tried this on the street, but it makes sense.

Try this instead...Change down quickly just before you are finished braking and about to start your turn.Ease out the clutch before fully disengaging the brake.No need to blip the throttle plus the back tyre/wheel shouldnt move about or lock.

If you want to blip ........try this...........

Make a circle with the thumb and first two fingers of your right hand. Touch your palm with the remaining two fingers to mimic a two finger braking position. Hold your wrist and the back of your hand parallel to the ground, and then rotate your hand and wrist down to simulate a blip. As your wrist goes down open your fingers , as it goes up close them . This is how I got over tapping on the brakes when I did'nt want to . I hope that was clear and not stupid sounding.

One question,

Do you have to blip the throttle with every gear you downshift or can I just go from 4 to one then blip the throttle then release the clutch.....etc. I always blip for every gear I downshift, because im unsure what will happen if I do a large downshift and blip once for that shift.(Call me dumb if this a stupid question)

I match revs on every downshift, one gear at a time, always have, always will. Done it on every street bike and every car (called "heel and toe" in the car world) I have every driven - although it was really hard to do on a VW Vanagon ;)

Only bikes I don't do it on is the dirt bikes because the dirt provides the cushion for the drivetrain so matching revs is no big deal (and I have a hard enough time holding on the the damn bike anyway!).

Too much of a habit to change after almost 30 years of riding. If nothing else, getting it "just right" takes perfect timing and skill, sounds great, and is fun. That's why we ride, for fun, right?

Keep the shiny side up.

To blip or not to blip......I've switch to the R1 from a V twin and blipping was mandetory on those.
