Rev Matching. Do you?

I do it often, even on the street when engine isnt revved to high just, for practice i guess, I still have a little trouble with smooth breaking action while blipping.

Does anyone else blip like Cloner?

I use my pinky and ring finger to blip with index and middle on brake lever.

Since I switched to the CRG shorties; it is really easy. With the longer levers, my knuckles would get jammed up a little at times. I do still trail brake a bit though with my toe to keep things settled when entering with a little more speed than I planned on

Prior to having a slipper clutch, always blips the throttle to push down gears. But I continue to test the ability of slipper clutch more and more, it really does a spectacular job. Now, I say let the machine do its work.

Same goes to the DQS, the more you push this bike, the more it amazes

I still dont understand. maybe i do it you are saying when you downshift you rev the engine first. how do you know when your reved match.

Hi fmvolume,

Rev matching is the process of bliping the throttle to momentarily increase the engine revs to match the next gear ratio when down shifting.
It provides more stablility/safety when decelerating by helping to prevent a possible rear wheel lock up (especialy on high compression engines with large cylinder capacity).

Oh ok, I thought that's what it was..... good to know. Thats what I do when I ride , had no idea that's what it's called, much appreciate it

2 easy ways to know:

1- you will hear only one continous engine note as you release the clutch...not "whaaa-whaaa", but one long drone until the next blip/downshift all while braking

2- the bike will not "feel like you threw an anchor off the back" if the revs are not high enough and it will not lurch forward if they are too high

Just practice that and then add in braking simultaneously and you're good to go.

You can hear guys doing it wrong at the track all the time with the double engine sounds as they release the clutch at the wrong revs in the braking zone.

(best to be off of their line if you are coming up behind them into turns. You will see first hand how unsettled the rear can get really fast with those guys when you go to your race school)

Does it help with the heat?

Brad I agree, thats a good summary, might switch to Hi again and see the difference.

Gunny I also agree in as much as this is what the bike was designed for, it's not a frail 900ss from the 90's and I love the sound of decel dropping down two gears entering a corner, and EBC stops me locking up. It's also the point that most car drivers realise you've arrive behind them before you fly past at the next opportunity.

RSR - I can't help but think this is what the aids were designed to avoid the need for blipping the throttle, as blipping takes precious milliseconds seconds into a corner. (wait...) Having said that my experience on the track is that EBC only goes so far and I've had the rear squirming into turn one at my local track, and I watch the Isle of Man TT (not MotoGP) and the riders are clearly and aggressively blipping their throttle coming into the tighter corners. (Maybe they don't have EBC?)

Ultimately speed matching avoids locking up the back wheel (and minimising stress on the gears etc) but really its the rear wheel locking that we're really trying to avoid, which is what EBC does. On all my previous bike but especially the Guzzi (shaft drive) and Jota you could completely lock the rear so easily it was mandatory.

Who'd have thought this would be a contentious topic!?

Guys,

Manually blipping the throttle (particularly on track) is still a must if riding hard and fast, but the manual slipper and the EBC do help in terms of stopping the rear end stepping out badly if you f&%k it up......

Race bikes have blippers built in - high end WSB and MotoGP bikes don't need to be manually blipped, but when the riders are braking hard and just stamp the lever up the electronics blip the bike before allowing the shift to go through. Just listen to them, but you don't see the riders right hand have to move (as we have to manually still do it), which allows them to concentrate on braking that little bit more intensely.....

Somone I know had a demo ride on a WSB bike and he found it really hard not to blip - but the tech told him specifically to avoid doing so as the bike would do it for him and manually doing it would screw up the system. He then found he had to concentrate hard not to do it! But said the system was fantastic.....

I'll just add that this is a milliseconds thing, not a concerted effort to precisely rev match. Braking is braking and blipping is blipping. You can always do one without the other. The best way to learn is at a moderate pace without brakes. At a "no brakes" pace, as you decelerate for entry and are shifting down, give the throttle a quick 1/8 turn bilp just an instant before you begin releasing the clutch and see how it feels. It's easier than it sounds. Later, while sitting on the bike at your favorite watering hole with the bike off, pull the brake lightly with one or two fingers (I use only the middle finger with my index finger just lying on the brake lever idle) and practice maintaining constant pressure on the lever while blipping (again...just an eigth of a turn or less) and you'll get the hang of it. Next practice light braking while blipping (you'll find brake lever effort increasing involuntarily initially....but it'll get better with practice) until you figure it all out.

Easy.

I generally trail brake on the front, too, RSR, but that's just me. I only use the rear to settle the suspension a bit on entery.

There is no better sound in the world as a Ducati and its engine braking as one lets off the throttle!

Sorry Gunny, but i have to disagree

Try Googling the following on youtube:

1. Low Spitfire pass.
Please don't tell me your ass didn't pucker a little and the hairs stand up on the back of your neck
I reckon ..... were well and truely trumps for the reporter.

2. Great Sounding Merlin Engine "Spitfire Sounds"

3. WW2 Mosquito Fighter-Bomber at low level

Question: Whats better than the sound of 2 Merlins on one aircraft ?
Answer: 4 Merlins on a Lancaster

In the Dam Busters movie, i love the sound of the Lancs in the scene where they are practicing low flying over lakes and they take the top off a tree with the rear wheel undercarriage.

I blip! Its fun to do it and it does settle the suspension as you are braking hard. I also do it as mentioned above as I also own bikes that does not have Slipper/EBC.

I'm a blipper too. No clutch needed if you're useful at it.

And as for Brad's "sound" comments, no disrespect Gunny, but yes there are plenty of motors that sound better than a Duc on decel. This one for instance:

BRM V16 Engine Sound - YouTube

If that doesn't make the hair stand up on the back of your neck, well I hate to break it to you, but you are DEAD... ;-)

Wtf???????????????

You HAVE to be kidding me with this?

This is a Ducati forum, not a historical bi-plane forum. Hell, I could have said close air support from a Cobra gunship directly overhead when I was pinned down in a firefight in Fallujah which saved my ass but I chose not to. So we disagree to disagree copy? Carry on.

What's that?

The sound of freedom..

It's not a gun forum either, but.... There was this time my neighbor tried to gun me down, but his cap gun got wet and none of them would fire - pretty TRAUMAtic for an 8 year old..

Srsly? This is getting out of control and stupid.

Agreed Gunny.

I appear to have digressed away from the topic at hand and caused a dissruption.
I will endeavour to not let that happen again.

Im a blipper....been doing for the past 25years of track riding and racing...

Still do it on my Panigale "S" no matter what setting I'm on with the EBC...
It just makes me much smoother than the other guys who aint blipping...and still have slipper clutches...

Back to the topic, I gotta agree with RSR and some of the other guys with regards to blipping still being a necessity. While testing the bike, I've played with the EBC at multiple levels and it is NO replacement for proper blipping technique, particularly when pushed from high speed to hard braking.

Although EBC kicks in within fractions of a second, I've noticed that you're still upsetting the chassis slightly but relying on EBC. You may not notice any instability at moderate speeds but when pushed hard or while trail braking, there is a definite unsettling of the rear end when relying on the EBC. The point of blipping is keeping the bike's chassis stable BEFORE it gets unsettled because a good majority of the time you're braking hard so that you can enter a turn at maximum allowable speed and the last thing you want is a loss of MAXIMUM traction even if for a millisecond. To me, EBC is like ABS - to be used as a safety net in case of human error not as a performance enhancer for a lack of technique. I don't think it was designed so that you can dump your clutch from 5th to 3rd as a new riding style.

As we all know here, the key to keeping the rubber side down is consistent technique that is employed at all times, whether street or track, which leads to smooth riding and safer riding; and ultimately faster riding. I'd encourage everyone to continue to blip the throttle as it's also the safest technique when the unexpected occurs during a downshift and you need to brake harder, change direction, and/or accelerate again.

Good thread guys. I like hearing about other techniques from experienced riders. Maybe we should keep a running thread or have a different section. As an example, trail braking would be a good topic because it's so effective with this bike. The combination of powerful brakes and easy turn-in makes it an awesome advantage on the track. As a side note, I also use my ring and pinky finger to blip with standard levers although I may switch to shorties soon.
