Ducati throttle SPACER

I was just trying to measure it with clinometer app.
It's roughly 65 degrees also.
So Domino won't help.

(Bro did it, whitout talking to me at first)
thank you @jrkk

had a look at the removed stock grip. i would bed a beer that 65 is right.

So here's the thing about throttle spacers. I put them on both any Streetfighter V4S snd my Panigale V4S. My local Ducati mechanic gave me a good old talking too though. Even though I liked the way they worked, he said that they screw with the ride by wire settings and can really cause problems. He was deadly serious and I trust him. He's been woking on my bikes for years. FYI

Did you ever experience a problem?

I dunno about this …. TJ Schultze, installed em on my 2013 1199, and Moto Union installed em on my 2018 V4s. IMO Required to have better throttle response especially on track/at speed. At no point did they suggest it could be a problem or cause damage etc. to ride by wire or electronics . after 18k + miles on track, never a problem. It’s the first thing I did to my V4sp. Throttle slop sucks and is a problem when transitioning from brakes to WOT. Really no reason for this. If you know something different about the engineering / design please share. I see it as a nuance overlooked to emulate old school cable based throttles.

I have a suspicion that when guys start jamming zip ties and rubber tubes to take the throttle slop out is where any ride by wire problems come from.

I thought they were gimmicky but gave it a try just in case it made a difference. For me the spacer didn’t do anything significant for my brake to throttle transition and was mostly a pointless mod that might make your head feel better.

ECU still reads 0% as well with throttle closed and spacer installed, haven’t noticed any issues either.

What kind of ride by wire problems have you seen or been reported?

Clearly there is slop in the throttle which you can see from bikes on the showroom floor. There is no true benefit and I’ve never seen an error code or heard one being reported from its usage.

this mod (not product) is done often by riders who take their bikes to the track including by motoAmerica racing the V4R, previous panigale platforms. I know some techs who fill the gap with something else and address this. An upgrade to a 1/8 turn racing throttle also makes it goes away. Transition from brakes to gas holding maintenance throttle is where it is most apparent. Specifically for RPM mgmt. once again riding on track. if you don’t feel it, haven’t experienced it doesn’t mean it’s not an issue and gimicky. It’s legit and can be demonstrable on a race track. You might not be in tune with this and adjust your riding style around it.

Oh I feel the slop, I’m just saying the slop doesn’t make a difference for anything tangible for me. It doesn’t affect my riding, track or road. It did no harm either so I left them installed. My brain likes not having the slop, so that’s good enough. A lot of riding is mental preference.

You should perform a test; take them out and ride on the track and on the street. From your experience riding with them installed, once removed you will notice a difference physically. If you don’t leave em out, don’t work anyway right ?! I’ll bet you put them back in or disregard the test. Having slop in the throttle sucks, think we all agree. Scalpel not as sharp, throttle response simply not as good.

Sure lots of riding is mental but tough to claim the mod is gimmicky while you ride around with them physically installed only justified with mental preference that do nothing. Perhaps your feedback loop doesn’t discern the difference. Try it and let us know. removing them would help you see there is a difference.

I only installed them as a test since I had the throttle off for something else anyway. The slop never bothered me. If I’m back in there again maybe I’ll remove them and see how it feels with the slop back in. My guess is it won’t make a difference to me, but I get it if it does for someone else.

I wouldn’t be surprised if Ducati put that slop there on purpose since it would alleviate inadvertently applying throttle while braking. This typically happens when the brake lever isn’t positioned in the right spot for the rider.

I don't remember who or how long ago it was....

Someone here had an issue where the spacers must have been just a small bit too thick and it held the throttle open just a smidge(technical term LOL) and the bike wouldn't start. Once he took them out, everything worked normally.
I never tried opening the throttle while starting, just something to keep in mind.

That happened to me. I had them on my V4 and would occasionally have issues starting. It was odd because all of the requirements for ignition were there, spark, fuel, etc. but it just wouldn't start. Endlessly cranked over until the battery had no more juice. Ended up having to bump start it, which with a slipper clutch meant rolling 25mph down a hill in 3rd then dumping the clutch while pressing the starter button.

Took it in and it turns out sometimes when the throttle was shut, it would ever so slightly indicate open. Since the newer bikes like the V4 reset the TPS every startup, if the throttle was registered cracked open while initializing then it would .... up fueling and make starting difficult.

I also know a guy who had them in his 1199 and found they were not allowing the bike to hit 100 percent throttle.

They're okay but I took them out and continued to use my V4 as a commuter for 2 years. It quickly got to a point wherein the slop wasn't even noticable. If people actually rode their bikes then the spacers wouldn't be necessary.

Glad this worked out for you. But when you suggest we should ride our panigales more to get acclimated to a sloppy throttle I put 15k on my 1199, 3.8k on my V4s, 600+ miles on the v4sp; 98% on track. How much more riding shall I do to get used to “slop” in the throttle? I’d rather it be tight than loose…this makes a difference on track for me most certainly. Tenths of seconds, millimeters of additional movement matter. Perhaps street riding is different and less of an issue.

interesting; instead of addressing poor rider technique, “inadvertently applying throttle while braking” [bad] engineers add slop. I guess with so many other rider aides this could be true. Why not sell it as a benefit for safety throttle ?

Yet we don’t see this on other applications such as the Bmw S1000RR. Dunno about other make:models. Even so Tight right off the showroom floor.

I wonder if there are any ducati techs on the board who could chime in. The fellow who suggested it could hold back 100% throttle and or cause start up issues sounds like it could happen. Although it didn’t for me.

Is this a design benefit or flaw? Many of us have our own take. But since it’s not cable actuated why build it into the throttle mechanism?

The average coffee shop Ducatista wouldn’t have the first clue how to properly setup a bike both from an ergo or mechanical perspective so if my theory is accurate ductai is smart to build safety into the bike for the sake of their ignorant riders.

On the 100% throttle part, I’ll check mine today via my aim solo 2. It it doesn’t show 100% spacer is coming out.

Suzuki shuts the butterflies instead of designing in throttle slop. It requires going into the ECU and turning that parameter off to rectify.

If I can remember, I'll check my SFv4S This weekend with the Solo2. I have spacers sitting on the kitchen table waiting to go in. Could also load up the data logs from COTA a couple weeks ago and check the throttle position

good idea. Let us know your result. Assuming you are on track, use speed as another variable. Does it make a difference ?

When you get into RPM mgmt techniques
this is our primary interface akin to a tuned instrument.

And for those of us who’ve been riding/racing last couple of decades prior to electronic traction control, analog was the wrist. We didn’t have all the wizardry to save us. Even so these are lauded as safety benefits. Not true for throttle slop from Ducati.I’d bet you be hard pressed to find anything about this benefits or otherwise.

Dunno if I agree with engineering to work around poor habits and ignorant riders. That could swing the other way. Nano second delay causing a misstep. Imo, when we talk performance riding street or track education makes a safer rider. They should learn how to activate better transitions from throttle to brakes. Sometimes when trail braking using both.

how many riders actually check their pressures pre ride if ever? How about get their suspension tuned to their body weight,
even a basic sag setup ? Do they even know what the clickers do ?

running track days, performance clinics for over 18 years in the Midwest gotta say hardly any street riders can answer these questions or come prepared with tuned bikes.

An instrument out of tune is prolly something a pro can handle like a musician to his/her guitar. However, to a noob, this could be detrimental. Simply not ideal.

education is better than ignorance; trial by fire hurts.
