whatup y'all

so, I am just trying to get a consensus viewpoint on this subject. My 600 has a slipper clutch, but I can't bring myself to kick it down two gears at a buck 20 and let the clutch out. I simply must blip the throttle. What do you guys do?? I was watching motogp and they had a camera on Rossi's clutch hand and he was working the clutch from his braking point until he was well past the apex, and his bike has a slipper clutch and some super sophisticated TC as well.

any input is appreciated..

My current track bike(05 zx6) has a slipper clutch. It was the first bike I'd ever ridden on the track with one. At first, I was blipping the throttle, because I had to do it on my old track bike(04 gixxer 6).

Then after a while, I realized its just much easier for me to just drop the clutch after each downshift without blipping at all. One slower, heavy braking corners, the rear slides for sure, but its not nearly as distracting as the "skipping" that occurs on non-slipper bikes.

Rossi and co. have such crazy technology on their bikes, that's why they can hold downshifts to the apex. Aside from my bike being no Motogp bike, I'm no Rossi. I downshift before corner entry.

The slipper clutch easies the compression of the motor when braking to help prevent the rear wheel from braking loose. Blipping, simply syncronizes engine rpm, and rear wheel to lighten the torque pressures on the clutch. Watch Spies and company as they negotiate tight turns.

I fully understand what a slipper clutch is, and what blipping does, and is for.... what I am saying is that I know that I could just let the clutch out, but I still blip, and I have watched pro racers that have slipper clutches and TC still work the clutch lever ALOT during braking, corner entry, and even off of the corner, almost like railing a berm on a dirtbike. I have raced professionally (not sportbikes), and am a relatively advanced sport rider, so I am just really wondering what technique the racers on this board use / recommend.

Blip and work the clutch. IMO it seems like a good habbit to keep if you ride other bikes other then your own or if you forget to sit as far back as possible on hard braking corners.

I used to hold the clutch a bit till I cracked the throttle as it seemed to ease the transition then I figured out it was chain snatch and the problem went away.

Blip the throttle and control the clutch softly and you can match engine RPM to road speed and with the help of the slipper clutch you will be also railing into corners.

The big difference with the MotoGp and Pro AMA folks is that they all have crazy technology to help with the engine braking.

First instance the Yamaha M1 uses a controlled fuel injection mode to help keep the fuel going into the engine so in actuallity the gas is never really shut off going into corners even if Rossi does have the throttle shut off. The engine breaking is what actually upsets the bike and the more Hp you have the upset the suspension will be and that will make you crazy nervous going into corners.

So like everyone has said before. Just keep blipping the throttle and good clutch control.

I'm sure technology will invent a system which tame even the meanest engines and make automatic sportbikes.

Oh yea, I ride a 97 gsxr 750. No slipper clutch. Just a lot of blipping!! Its fun!

I blip it too man, force of habit. It's good to know that the slipper is there though in case you end up needing it:cheers

I blip 99.9% of the time. Even in my Mustang, I usually blip on downshifts (heel & toe driving, sort of.. my right foot does both brake and gas in the car).

It's still a work in progress to get better and smoother, and always will be, of course!!!

sometimes i do, sometimes i dont. If i am kickin it down 1 gear after a short straight, i wont usually blip, i will just kick it down and throw it in. If it is more then one gear change, i usually will blip.:dunno

Differnt strokes for differnt folks i guess.

it depends on the corner but some corners it is better to blip then just drop the clutch. it will allow the rear wheel to break traction while still free wheeling allowing the rear to come out a little and help line up the corner.

I was used to blipping until I got my slipper. Now I don't blip but I will feather the clutch to controll engine braking. Could this be why the GP guys are working the clutch so much?

MotoGP bikes automatically blips the throttle when the rider downshifts. thats why you dont see then blipping the twist throttle. Thats what we need on our bikes.

Where did you learn that??:scratch

it is common knowledge if you follow the technical side of the series


I was just at the motogp at Laguna Seca

up close, those bikes make fighter jets look simple.


the bike's suspension setting can be programmed to change in between corners so that they are always optimized. they have super advanced traction and wheelie control, as well as ABS systems that would make your SUV blush.

they are the absolute pinnacle (well motogp and F1) of technology applied to racing.

They don't have ABS...:nono

I know this will probably sound like a noob-ish question, and sry to jack the thread...but I'm a relativley small individual, and I've always had difficulty with trying blip the throttle while simultaneously applying constant pressure to the brake lever. It just seems like my hands are too small...i've been working on it for a while now trying to get it right, and most of the time I get it, but it just doesn't feel comfortable. Is there anything that might help out a bit? I was thinking about getting a decent set of aftermarket levers, since I still have the stock ones on...but I dunno how much that'll help.

1st, move the lever as close to the throttle tube as possible. Next, you must master the art of actuating the throttle with a twist of your wrist, kinda like tuning a doorknob. Your elbow shouldn't move at all from off throttle to wide open throttle. I find that I am able to brake as hard as I need to with one finger, but you may want to used two if you are a really little dude. You will find that the "doorknob" approach to throttle acuation has far less impact on braking modulation once you have it down.

good luck!!

that is not what Nick Harris (motogp announcer / expert) said at the motogp pre-party at laguna this year. :dunno

Matt Oxley wrote a article in Road Racing World a month or two ago about the lack of ABS on GP bikes. he seems to think, as well as some team managers thats it on the horizon, but not in use at the moment. its much more complicated to design a ABS system that will work, and well than a TC system...

I stand corrected (for now).

I'm pretty sure they don't have active suspension either.

Forks are pressurised but so are some superbike now (have been for a while), hell you can buy them for your road bike if you want and have tens of thousands laying around for a set of forks.
Rear shocks are just normal - Uber high tech version of the TTX on Rossi's bike , most are running Ohlins , some are running Showa. Haven't seen Penske at Motogp , but plenty at Superbike.

Active Hydraulic Suspension , weighs a tonne , has no springs !!
The pump would rob too much power from the engine. You'd have fluid resovours , lines running to forks , the rear , a computer for front , a computer for rear , a can bus system/hub to talk to the main computer , which for most is the magnetti marelli (suzuki run a Mitsubishi) , which doesn't control suspension , so additional computers would definately be needed.

Would be nice , not yet though!

Hey, listen... after 27 bikes or so in as many years... my hands have not gotten any BIGGER... but I STILL BLIP on ALL shifts.

I like the "doorknob" description... and would further suggest you LEVERAGE your inner thumb-forefinger-palm area... AGAINST the inner flair of the throttle grip... and you can "compensate" for "less than large" hands. Aftermarket levers (especially adjustable one's) can also improve this.

Another consideration is, IMPROVE you BRAKES (if not already) Braided/kevlar lines, race pads, etc... and a lever with greater (adjustable) leverage, can enable MORE of your physical capacity and mental focus to be on THROTTLE CONTROL, with gentle touch sufficing on the brake.

(PS: HAM-FISTED riders may reconsider the MEGA-ABRUPT brake set-ups...)

damn, beat me to it. :biggrin

haha i dont mean to sound like a tard but.... this blipping you speak of. explain? please!

Blipping is giving it a bit of throttle between gear changes down. I do it every gear.

For me above is 100% how i do it. And i have small hands. Well sort of. But thats how i do it and its perfect.

thanks! that's what i thought by how everyone was using it in context! i do that already, just didn't know the correct lingo! :wacko

I blip 99% of the time, but i do know one place where i downshift and dump...coming into T2 at Nashville.

I downshift from 6th to 5th as i come off the oval, then from 5th to 4th right before i tip into T1.

T1 is a 4th gear, wide open turn (600cc) and then as soon as you stand up out of T1, you have about this _______ far to get from about 120ish to about 40ish to hang the 180deg hairpin T2.

As soon as i stand up out of T1, im hard on the brakes while i bang 2 downshifts into 2nd and then dump the clutch.

Im not saying that is right or wrong, im just saying that is how i handle that particular turn.
