That dummy connecting rod is genius! 🔥😲
That's a "no-no word"! Now, we say "special" connecting rod!
@@hugejohnson5011 I prefer "retarded" connecting rod
@@LizardHunter777 Well yeah! But, in today's world, people are out there just waiting, and hoping to ruin someone's life or career over one public word like that. And, it is a shame, because with social media, and everyone being so butthurt all the time, one has to be careful not to hurt someones sensibilities. All of which I do find to be pretty retarded!
@tallwill38 Nice argument bro, it was literally added to increase reliability.
I gotta admit, Ducati has made some pretty cool and unusual engines. This single is wild.
There's nothing more definitive of motorcycling than the sweet tones of a big single at work.
The sweet tune of a inliine four is what does it for me.
Yeah, you got that about right. Something about a thumper that connects with your soul in a sort of primordial way. It's spiritual thing.
even a 4 stroke 50 cc sounds decent
This engine is no thumper, especially at 10,000 rpm...
@@t16205 A Ducati Bevel Twin or a straight six for me.
I can remember the Ducati Super Mono being raced at Donnington Park. Some of your footage was from that venue. I was and still am a huge fan of single cylinder engines, i so wanted them to make a production version of this bike!
I done a load of composite work on the Chrysalis Sper Mono's that wiped the floor with those Ducati's in the 1999 TT , 1999 Championship and the 2000 TT with John McGuiniss riding after the untimely death of Dave Morris.
Dave had made the cylinders of 720 and 750cc that fitted on the BMW/Rotax engine. I have the 2000TT podium photo on my office wall Chrysalis 1st and 2nd Ducati 3rd.
Your English and video quality has absolutely become high quality over the years of watching you. Keep these coming Its so much fun to learn with you, seriously it's so visually easy to enhance my automotive knowledge with every episode
Thank you! Glad you are learning this easily!
Thank you for all the research and effort to provide all the time very interesting content ! I am amazed by the amount of creativity that went into that engine
A friend's dad used to race one of these. I still loving looking at the pics I took way back then! Beautiful bike.
A rare, special channel, showing Ducati engineering from inside the company. Thank you for such research! 🏍️ 🛣️
As always, a very interesting and informative video about an engine that only a handful of people knew anything about. Keep up the great work, can’t wait until you put out the next one. 👍🏼
Oh, we haven't died off all of us yet...🏍🏍
This channel is peak performance. True power. No lag
You always come up with something killer all the time! History and performance in one! What is next , I enjoy all of your videos and the hard work you always put in to you and your videos. Great Wednesday to you and your family when you get moving in the morning!
This was awesome! Thank you. You do perfect work.
Great video. Thanks. I remember the hoopla around these when they were in development. I'm glad that my 996 had both cylinders though!
As usual, great research on your topic and with rare to be known footage
You have the most fascinating content. Keep up the good work!!!!
The quality of your videos has greatly improved over time, good work
Thank you!
I am impressed by the amount of thought that had been put to engineer this bike, just for competing in a race with a rule that hurts the performance of the bikes.
WOAH! That dummy cylinder is a super original idea! :o
This is cool. Desmodromic valves are quite interesting, and the connecting rod stabilizer is also neat.
This bike seems fun. It's super light (I think) and has decent power. It's cool.
I wish there had been such a balance rod on my 1971 Ducati 450 Desmo thumper! My hands would get so numb I could barely hold on, but what a piece of sculpture the bevel drive Ducat singles were!
Oh yeah. My singles were fabulous to ride but the vibration kept my rides short.
I still have a 450 Desmo-it’s the Desert race RT version, the vibration on mine is not too bad at all-but then allegedly the RT’s engines were assembled in the race shop so perhaps were better balanced.
GOOD video, i knew about the supermono but i don´t know how you got a lot of the information but i apreciate it
Thanks!
Great video, didn't know about this, very interesting and very cool...
I always enjoy your videos !
Thanks for the education! Great video.
Brilliantly done mate!
Now do the Rotax Husqvarna Nuda 900R engine that is derived from the F800R
Yes
Is this channel creator your slave. "Do the..." ; A calm word would be appreciated
Why? It's just a 270 twin, albeit a good one
@@christianhodges685 315 degrees twin with 13.1:1 compression ratio, 10kg linear torque from the start and that funky balance.... calling it just a good one is like calling kim kardashian a beautiful woman.... You really don't know what you're missing until you've ridden one...
@@gt4654 ok but it’s nothing really special nor strange.
VR’s focus is to present really quirky and innovative engine, there are a lot of good engines that are still “normal” and not really interesting from a technical or historical point of view.
Ducati’s supermono was quirky and both tecnologically and historically relevant.
Rotax’s 900, although a pretty good engine, had nothing really special to make a video about.
I raced against one at Loudon Motor Speedway in New Hampshire in the mid-90s. The AMA let everything on the track for 8 laps after we got our racing licenses and the 600s were killing everything in the corners except for the SuperMono. It was going UNDER them in the corners, it was so nimble, like the guy was on a jet bicycle. We heard later it was a dentist from NYC.
Great job, an engine that many will have never heard of.
china should make and produce these kind of engines as replacement for current bikes
I remember rooting for it until I saw the price tag. Still love the Ducati Singles. Falcon Tattoo.
Thanks for the on track video and Dyno.
Great video👏 Thank you
Ducati have just released a video of the Superquadro Mono !
Nicely done! They brought a version of this back with the new Hyper 698. Be cool to see a naked sport platform around this powerplant someday 🤔
Love how you get technical but not so much that you need a degree to understand eg how you explained how Ducati removed one cylinder and added a second dummy shaft so cool.
Visio Racer has Best Engine Videos.
Have a Beer from me Cheers.
We have a Yamaha SRX race bike that my dad used to race. I think in its most powerful tune it was on par with this. But definitely not at 550 cc. With the mild piston we have on it now, it’s probably making about 60 horsepower, at just a shade over 300 pounds soaking wet. It’s a glorious thing to ride. 100 times better than any mega-power new sportbike.
I was going to say....My MZ Skorpion, which came from the factory with a Yamaha 660 single at around 48 crank horsepower, put out 70hp at the wheel and weighed about 300lbs when I was done with it, with plenty of room for more output should you feel like testing the limits. My build was somewhat conservative because I wanted to be able to run it 10k rpm all day with no worries. Oversized valves and some porting from probably the best person in the country regarding the Yamaha 660, a moderate Megacycle cam, flat slide carbs, full race exhaust, and some other mods for bullet proofing. The gear train for the balance shaft and the decompression mechanism both need modification to run at sustained high rpm. It was a wild ride for sure. You couldn't keep up with a liter bike on long straights but it would eat them alive in the tight twisties. 😁
@@shmaknapublar does that porting guru of yours happen to be named Mike? And also, I hope you have a Jemco megaphone on it. They sound incredible.
@@ImInLoveWithBulla Kenz Cycle Tech out of Mesa. Not only is he good, but a real honest mechanic/tech. If I remember correctly, his valve seat cutter had a failure when cutting my head so he upgraded me to oversize stainless valves and re-cut them for no charge. He educated me on the art of porting in regards to not just removing as much material as possible, but maintaining a nice taper all the way to the valve opening to keep the flow accelerating. He also ground down the stems a fraction and contoured the valve guides to maximize flow. Pulled like a freight train all the way to 10k when running on the track ignition. I set it up to run on the factory box or a programmable ignition at the flip of a switch.
I especially love the refined sound of a dry clutch
Wow! Fantastic video! PS: When I was a kid, ANY 500cc Single was called a THUMPER!
In the 70-80's had several Ducks, loved the singles, but I am also a die hard fan of the old Yamaha XT-500, so you see I have a soft spot for a thumper.
great doc! thanks!
I had a baby Duke in the 70s. A 160 cc 1960s road bike! Loved the beautiful clean lines of the motor. is was a ins. Write off.Had the forks straightened,tidied up the rest and road it to work.Who ever wrote it off must have had very sore family jewels as the tank had a large dent you know where!! Mal.
It was so simple, yet so effective is crazy
I'm biased, as an Italian... But i've never loved a bike manufacturer more then Ducati. My first bike was a Monster 600 and the sound of that dry clutch... It's so distinctive, i love it.
,WAW. SUPER. AWESOME VIDEO. TNKS👍👍👍👍👍👍👍👍👍👍👍👍👍♥️♥️♥️♥️♥️♥️♥️
So simple, so 🤯.
Visio Racer 👍
Bucket list bike!!
It’s so cool seeing footage of barbers museum. It’s a quick ride away from home😂
Loved the super mono
Matching the acceleration/deceleration curves of the piston with the dummy rod or dummy piston is a much better approximation of the forces involved than a rotating mass. It is more common than you might think. Yamahas 500cc scooter engine is a parallel twin with a third dummy piston at 90°.
Really mind blowing
Excellent
The Yamaha T-Max 500 4-stroke parallel twin scooter motor has a dummy cylinder like the BMW 800.
Why it sounds like an old Triumph!
Very cool engine!
The sound 😍
Mr. Visio Racer please reveal the synthwave beat you’ve been using in your videos, it fades in starting around 0:45 in this vid and I gotta go for a drive listening to it. Name that beat I need it in my life!!!
* 0:40-2:55 best I can tell when it fades back out
An interesting way to approach engine balancing. Who ever thought there could be such a thing as a V-Single?
I like this video.
My Father has gave Me his older Ducati 900 supersport (888 style fairing) .. I can't wait to get My License sorted out and get it out on the Road.. the noise alone sends Me weak at the knees lol.
Please do the history of the MV Agusta F4 and how it came to be
Visio talks Ducati, I listen
primary and secondary engine vibration DOES NOT impact its lifespan: the forces associated with with these vibrations are experienced by the bottom end regardless of balancers. vibrations can however shake apart the rest of the vehicle
What's crazy you put they valves on any engine and you will get more power in mid and hi range cause it breathes wayyy better for the engine and 0 valve float
If that were true why don't race engine manufacturers use desmodromics?
Because the truth is desmodromics were past their prime in the 1980's and ,today, systems using pnuematic valve springs surpass what desmodromics can achieve
It doesn’t inherently breathe any better. Power gains would be mostly from not having as many losses fighting valve springs.
At the time it was a big deal since valve springs would tend to break and have a lot of problems with sustained high rpm use. But, with modern double or triple springs and better metallurgy valve float and spring harmonics are much better controlled while also allowing for higher lift.
Ducati makes some incredible engines, I have always wished that they had made a desmodromic V8 car engine.
Mercedes had one way back.
Looked like bent washers spinning to open and close the valve.
Photos in early Ducati books.
Desmo engines are great if meticulously serviced. They’re powerful but delicate.
I need this engine for my KEI truck ❤
The second conrod simulates another piston and conrod assembly. But this second set could use a very short stroke, just to be compact, and must be heavier to generate the same forces that eliminates vibrations.
Robert Holden, one of New Zealand’s greatest motorcycle racers was the most successful Supermono racer, sadly killed on a 916 at the Isle of Man in 1996
5:54 it has a turbo for a water pump 🤩
funny that the idea "well the 2 cylinder version is balanced" worked so well
Simon Crafar at the begining, with pink on his leathers. Never won a WSBK race, but did win a GP.
Sure wish they'd build a single today... I'd be all over it! Had a 160 back in the day
I always wanted one....
Crazy when you think About how todays 450cc dirtbike engines rev to 14,6k
Having a super mono monster would be amazing.
What do you mean by: "dedicated cam" and how does that eliminate the need for valve springs? Were the cam lobes inside the rocker arms? As in the pivot point being at one end, the cam goes thru the rocker arms at the middle and the valve attached at the other end? Something like that?
Two cam lobes per valve, one to open and one to close
I believe the desmo system was a development of the pre war Mangoletsi push pull valve system
You will find one of these, I believe one of two ever built, in the showroom of BTS in South Africa. The carbon rim manufacturers.
I want one😮
Great work. Did the early subaru motors buy the vw design or rip it off? In case you are looking for more ideas
There's nothing unique about a flat configuration. By 1930, just about every piston layout you can think of, was thought of, implemented somewhere, lost, found again, lost again.
It’s a vw lump running backwards to avoid paying vw anything
@@Anax100 Yup, I try to tell these kids that some of what they think is "brand new" technology, has been tried 100 years ago. And but for the lack of modern materials, it is only now that some things can be successful. There were operable electric cars over 100 years ago, but no batteries to do the job. Now look at 'em go!
The first horizontal opposed "boxer" engine was developed by a little known German engineer by the name of Karl Benz in 1897, but strangely enough this innovation appears to have been overshadowed by one of his other inventions.
@@alexjenner1108 His motorcycle?
Such a noise. Love a ducati rumble 👍
has anyone ever tried to do research by combining the roller rocker arm +desmodromic valve system? as far as I know from various articles on the internet that desmodromic often has problems in the rocker arm, the friction between the rocker arm and the camshaft makes the rocker arm not last long,cmiiw
Was wondering if anyone had made a sleeve valve single,,with its much larger port area,,?,,and lack of,valve bounce,,
A walking stick for yhe piston. Who would have thought that 🔥
Gonna put this on my grom
WOW.
I wan to know where these old video and picture come from, because I don’t how to find?
If YOU knew how, you would be making these videos. He is a master of research
It's on the description
I wonder if you could use that connecting rod style on a 2 stroke engine.
It would increase the crank case volume, you usually see the cases being filled in on high rpm engines to decrease the volume. Depends on the rest of what you do I guess
Harley-Davidson used Ducati single cylinders in their late 60s and early 70 Harley thumpers, they were great motors but the generator was a failure, even the voltage regulator was faulty.
wow im going to fix a dummy rod to my 4 cylinder bike as well after watching this!
🐱👍🏿
That would indeed be a "dummy" rod.
At 8 . 05 it seams there is a valve spring at some point to push the valve closed....without the cam being in position...Or am I missing some understanding here..?
The valve is closed by an actuator driven by the closing cam, which is separate from the opening cam.
The older bevel desmo had a little jesus spring on the closing lobes to take up minor slack between cam closure and valve seat
How about the bloke that used the vertical cylinder as a compressor to feed the horizontal cylinder and got about 50% power gain
😎 That sounds awesome. Please would you be able to point me in the right direction to research this ?
Ducati should've used the upright cylinder as a compressor.
Ducati in 1926 was making radioes and electronic equipment ONLY.
They started making bicycle engines from a borrowed design under license, right after WWII as a post war recovery effort.
First motorcycles were 4 stroke 48cc developed from that first engine, in the early fifties.
I find this channel usually well documented, but this time you need to get some fact straight.
8:40 kevin cameron was there.
I have SZR 660 supermono and gsx-r 1000. I use only 1 cylinder SZR 660 on track days. It is other level of control, and riders feelings.
Didn't this dedicated racer kill the Sound of Singles (SoS), which was primarily fielded by bespoke racing machines with tunde/converted production engines?
The superMono was basically developed for monotype race !
damn imagine if ducati does a 450 supermoto
Taurozzi engine + desmo = mantap
Please, how do you know about Taurozzi?
He is from Argentina.
I got to talk to him.
Pendular engine.....
My Husaberg 650 Super Motard is lighter with the same power and revs, it just vibrates a bit more 😅
6:23 funny how much that engine sounds like the cross plane Yamaha engines.
This has been my interest; make a giant R1 from an LS v8 utilizing the Ducati supermono technique .
