The Desmodromic valve system has been around since the late 1800's (Gustav Mees filed for patents) and in 1914 the French automobile maker Delage used the desmodromic system in their Grand Prix cars. Ducati's Fabio Taglioni "redeveloped" the system for their 125 Grand Prix engines in 1956.

The modern Desmo design is not the nightmare to adjust the internet claims. It is as simple as any other overhead cam. It just has 2 shims per valve instead of 1 shim per valve. It is very durable and reliable. Ducati MultiStrada specifies 30,000 km between valve checks on the Desmo. A valve check does not mean adjustment. Because modern metals do not stretch as much as metals 30 years ago, it is not uncommon for the valves to not need new shims.

WOW! I love the way Ducati moves those valves! Thanks for the demonstration! I cant wait to see all these new bikes racing together in the bewr future! Cheers!
Funny, when I was your age, I could not wait to ride my affordable bike. All you can do is watch today? You should not be cheering, you should be angry.
Probably won't see a production bike til mid to late '25 from what I have read. I will definitely pay whatever the msrp is when the time comes. I just want it because it'll be cool and unique in a sea of clones.
Yes, there is no static resistance of a spring. But the spring could also break, rare but it has happened. With the desmo system the cam itself, fingers or bobins would have to fail for the bike to lose timing. Very interesting. I remember Mercedes using a Desmodromic system on a car years ago. It does pre-date Ducati. Regardless, more bikes with power equals more fun for us, the consumer!
There is static resistance/force of a compression spring that is preloaded but not moving. I have not even watched the propaganda vid yet, but with higher rpm's, it gets harder to control the spring compression (where it stops), when the cam changes it's direction, (the spring mass and valve wants to keep going instead of change direction with the cam--valve floating.). Not bad for a guy who builds 2-stroke engines for a living huh. :) OK,--more fun, for less consumers, as we go broke.
As a Ferrari F8 Spider owner and a 2023 Ducati Panigale V4 R, i think it's a cinch that the Ducati red will look the best...nobody does Red better than the Italians.
As an old school arena cross rider from way back when I can honestly say I'd ride it. I'm kinda partial to the old 500cc 2 strokes though power is power.
So it looks like that will give you more flex and more feel and more comfort as the frame will not have those really rigid adhesion points due to the welding. I think it’s a great idea that’s definitely like injection molding that they’re doing there. We’ll see what happens.
Learn something every day!! Never really thought about how Desmond worked before, cheers.👍🏼 But, to be honest. I don’t think more power is what a 450 mx bike needs. I have seen interviews with the best in the world who say they cling on for dear life and they are along got the ride and not always in control!!!😂😂
I"ve owned Ducati's for 30+ years so happy they are joining the mix. BTW KTM has had the rear brake lever tucked behind the frame for more than 25 years.
Ive heard of that valve system ages ago but never knew the principles involved... it should not only add HP across the board becuz of greatly reduced friction but should also all but eliminate any issues regarding valve float at high rpms...in fact this will likely be one of the highest revving 450 dirt bike motors out there becuz of the desmo system..wait for the 1st rides and the dyno #'s
Ducati didn't invented desmo but the developed it and patented the development, so the other manufacturer can't use them. For the adjustment, this is the fun one.. in normal valve spring dohc engine usually you adjust the clearance arround 60.000 - 100.000 KM. For road use Desmo max is 30.000 KM, racing engine max is 12.000 KM so this is the downside of the desmo, needs maintenance more often. The valve have 2 shim, opening shim, and closing shim who also act as valve collet retainer.
Special permission for what a dictatorship wants us to make and ride. That rule killed free enterprise advancements, and the bikes would be a lot more affordable with out it. (and the 1986 production rule, that also tripled the cost of a bike in 5 years with almost no new advancements like seen for a decade before that rule.)
The YZM was a Yamaha works bike in Europe (aluminum frame) from 1988, 2 years after it was said Yamaha could not afford to make works bikes, and spearheaded the 1986 production for the USA only. They still make works stuff for Europe today. The 1986 production rule, as explained, is a lie. Behind it was the FIM wanting to stop bike development in the USA with the factories, because we won the MXofN 5 times in a row. Both the 1986 rule and the 4-stoke forced on the industry, are the biggest factors of the sports decline by far. We need to demand our free enterprise back, because government is running our great sport into the dirt.
Owned a 1967 Ducati Scrambler, then a 350 scrambler and in 1973 a 450 desmo scrambler. Nice bikes. Overall the 250 was the nicest of the bikes. Ducati should have done this 30 years ago. I doubt they will overwhelm the existing manufacturers
Desmodromic was not primarly invented to reduce mechanical drag. It was developed to close the valves of a high reving fourstroke faster, than springs can. When the crank an piston can stand high revs, its the movement of the valves, that limits more. To enable the closing of valves at high rpm, without crazyly strong valvesprings etc. and with steel valves (not titanium with all its downsides about valveseat and cost etc.) It is desmodromic, what is needed to not suffer fluttering valves...
Idk, Desmo is neat, but i doubt it will be crazy different. Its a holdover from when material science wasnt up to snuff for springs. Now we have bikes going to 16-18k rpm with a warranty on valve springs.
Well this is exciting. I look forward to getting to ride one. Appearance makes it seem well thought out and put together. Exciting times. Typically there is still a lash spring in the system of desmo controlled valves. The rear brake pedal tucked inside the frame has been on KTMs since 1990 ish and still there on KTMs now including all KTMs clone army. Maybe other brands earlier. Front fender agreed is a huge mud trap. KTM had some big troughs there in the past and in mud race you would get several pounds trapped there.
I think that Ducati is going to shake the industry up and it is nice to see yet another European brand entering the arena. My hope is that when production does begin for the general consumer that the pricing does not end up making it a niche bike. Ducati does tend to bring a more lofty asking price compared to Japanese machines and even those are becoming harder to justify the asking prices when you consider you can purchase a base model Maverick pickup for just a few thousand more dollars. I mean ti put this in perspective a 2024 450 SXF by KTM is running almost $13.5 after destination and setup and that isn't even a Factory Works model. The Japanese 4 come in for a 2024 450 model at 13k for the Kawasaki and the other 3 between 9 and 10 grand depending on incentives and surcharges. If Ducati and Triumph exceed the KTM, Husky, and Kawi price tag by more than say 500 bucks I do not think they will gain much of the market interest outside of pro riders. Should be interesting to see what happens come race season too because if the track performances of the European newcomers does not live up to the past couple years of anticipation and hype, I do not see them doing well in general consumer sales. Just my opinion anyway.
Pricing won't make it a niche bike, it's limited production will. Ducati doesn't make many bikes per year - even though they are owned by VW they are essentially a small company. Ducati started building bikes around the same year as Honda. The year Ducati built bike number 1 million, Honda built bike number 300 million. The Ducati will cost around 15% more than a Honda and they'll sell every one of them they make. Which won't be many.
@@DezmoDog the reason I put it in a niche bike category is because of what it costs to make a modern interpretation of a KX or CR 500 using the latest chassis and updated engine tech. It was close to 15k to build a Service Honda CR 500 AF spec’d out almost 10 years ago and they are a very niche bike and like you mentioned low production numbers for the Ducati would be the main factor but from my standpoint the pricing also factors in because it limits who can feasibly access the units. 16 to 17k for an MX bike is a lot of money if you are an independent amateur rider or simply a weekend warrior hobbyist. Just saying.
Actually, Desmodronic was refined in the late 1930’s in the airplane industry, Originally designed in the 1890’s but not really used due to lack of ability to properly heat treat parts yet. First started being used in WW2 by the Swiss and Germans.
Too bad Aprilia left the train. With the MXV they had figured out most of the problems. Also if you do the known updates/ upgrades to your XV it will last without a problem as long as an EXC.
It's factually not true that the Desmodromic system has no springs. It's just that the springs are there to keep the rocker against the cam lobe, instead of having to close the valve. There is definitely resistance when you try to turn the cam shafts on these heads.
rode a 900 SS desmo v-2...wow!...Phil Shiling, an ex editor of cycle world magazine had a race team on 900 ducati desmo's...they did a bunch of improvements and seems i remember those Vtwins spinning at 14,000 rpm!
Just to let you know that the Ducati desmo valve train has been designed That way so the Engine can Rev more than engines with Springs engines with Springs can suffer valve bounce at high revs. Therefore, the Ducati is designed to rev more And deliver more power good video. Thanks
Love your clips mate! just wondering with the frame/head stem being one piece, obviously a forged piece, gee if they want to change any characteristics(?) of flex etc that would mean a whole new die? not as easy or cheap to change any minor detail issues? maybe thats why they are not going into production for a while, they would want to get this rigity/flexability correct? just a thought, keep up your great work! cheers from Australia
First of all I like the style even that front fender they are using. That makes them unique & very Ducati like bike. Everything you have said are good & made for performance. Although without any MX race under their belt. I'm sure of the components might a bit change if they can find some more performance in some areas. Anyway we we'll see. They have got two great riders who develops this MX bike.
I think all the plastic designers come from the "Batman school of abstract art" college. Abstract art has no place on my functional dirt bike. You can keep the bat wings and arrow tips,---what ever they are for. I replaced my front fender with an older model, and went "Ronnie Mac" on the rest of the cartoon plastic. Looks great. What are those wings for anyway? The artist does not even know.
I disagree about the front fender looks cool and it’s a reinforcement for strength. I think of some of the early ktm fenders would flap around more then normal. Ducati will stay nice and firm, also good aesthetic. I hope they keep it just like that. Would love to ride one I rode mostly Hondas and Yamahas that me started in street ducatis would love to ride mx on one.
In motocross the design of the bike has reached a sweet spot years ago. Power is not the issue, nor torque. Its is traction and suspension, and even there, it is the ability of the team and rider to fine adjust for the circumstances what makes the winner. And the biggest part of succes is the talent of the rider. The bike is not that important anymore. That makes the sport so nice and competitive, unlike formula 1 where you never can win without a big budget. By the way, the desmo system that Ducati uses is to avoid "valve floating" at high rpm. Motoscross bikes not running at very high rpm's. It has also disadvantages, one is a heavier construction, more mass to accelerate. If all of these design choices you talk about would be so much better, the other brands would allready have applied them, they are not stupid. And there are no "best" brands, only better products, that come with a higher price.
Look at the Koenigsegg car engine. It has pneumatic valves and computer timing. Zero friction engine rotation. This would be necessary if petrol engines are to keep up with electric.
Watch Ducati force a rule change in professional racing if this engine lives up to its potential. Desmo tech is proven, and I can’t imagine how high a 250 could rev. God bless Italy, and welcome to the world of off-road
Well it sounds competitive. Is it really one of the lighter bikes? Does it really have the most power and by how much? Most all the top bikes in this class have all the top shelf stuff to go with. Lets wait and see about results and reliability, handling, etc..
So here in 2024 when valve float is somewhat a thing of the past so why desmo? The system requires minimal hp to open the valves and mainly you can run a very radical cam profile without skip or float. BTW Taglioni went with the desmo system that Mercedes had perfected at the time (1950s). I just bought the hypermotard 698 and I love it!! Very fast too.
I think you misspoke. Maybe most powerful single cylinder 4 stroke. That does not include 2 strokes. 2 strokes cc for cc will always be more powerful still.
The head is very tall, and I measure from the photo that it may be the tallest bike in seat height. That is not a plus in MX, but MXA has accepted tall bikes. So will we,---again. I have never seen so many amateurs (go-pros still allowed for amateurs), so slow in corners.
Its great to have more OEMs on the circuit. But....do they all have to be backed by Monster??? First Kawi, now Yammie. Now it appears that Ducati will be Monster backed. How long before Monster absorbes Suzuki? Monster already backs Honda, in rally raid, and Baja. So... the clock is ticking on "Monster Honda" backing. I get that Red Bull KTM, and GasGas is a thing. Red Bull used to be a big thing in outdoors, but no more. Rockstar Husky is a minor player now . Our group started a drinking game, a few years ago..."take a shot every time Lee Doofus, or RC say Monster Energy". ....none of us were conscious at the first 250 heat gate drop!!!
This is definitely a totally new bike and it being a Ducati you can be certain they paid attention to detail. I think I’ll wait until they get a little cheaper though. Lol
Ducati coming to motocross is even better than Triumph All of their bikes are normal “full-on” beasts. Absolutely no “valve-float” with the Desmo valve train. Bet the motor makes 15 -20% more power than other brands. And never forget the hard fought lessons Ducati went through developing a frame riders could win with in Moto GP.
So. My issues with Ducati, is one, here in Melbourne, there’s only three dealers, so it’s a pain in the arse if you need anything “factory” done. Two, you only get 2 year’s warranty and roadside assist- you need to buy an extended warranty, of only 12 or 24 months, so for a prestige manufacturer that’s really unacceptable. BMW gives you 5 years and 3 years roadside IN THE PRICE! Three, some stupid design decisions - why on earth do they shove the air filter under the tank on the Desert X? It’s an hour and a half to get the tank off. Imagine you’re in the desert, on an extended trip, and you need to check it…! And it requires 185nm of force on the rear axle nut! So when you do chain tension, or need to put an emergency tube in, you need to carry a long handled spanner to get it off, or one that breaks down into pieces. Really, really stupid.
DesmoDROMIC, not DesmoTRONIC 😂😂😂 In any case I think you missed an important point: the single frame is another trademark from Ducati. All their sport bikes have the single frame, from MotoGp to Panigale V4.
I believe Cagiva also runs the rear brake lever behind the frame. But I would rather you have been a salesman for Cannodale 24 years ago, because they did not take anybodies money to make a launch bike into electric. I think we get dumber every generation since the 60's, and I don't think it is an accident.

Typically there is still a lash spring in the system of desmo controlled valves.
The rear brake pedal tucked inside the frame has been on KTMs since 1990 ish and still there on KTMs now including all KTMs clone army. Maybe other brands earlier.
Front fender agreed is a huge mud trap. KTM had some big troughs there in the past and in mud race you would get several pounds trapped there.
I think that Ducati is going to shake the industry up and it is nice to see yet another European brand entering the arena. My hope is that when production does begin for the general consumer that the pricing does not end up making it a niche bike. Ducati does tend to bring a more lofty asking price compared to Japanese machines and even those are becoming harder to justify the asking prices when you consider you can purchase a base model Maverick pickup for just a few thousand more dollars. I mean ti put this in perspective a 2024 450 SXF by KTM is running almost $13.5 after destination and setup and that isn't even a Factory Works model. The Japanese 4 come in for a 2024 450 model at 13k for the Kawasaki and the other 3 between 9 and 10 grand depending on incentives and surcharges.
If Ducati and Triumph exceed the KTM, Husky, and Kawi price tag by more than say 500 bucks I do not think they will gain much of the market interest outside of pro riders. Should be interesting to see what happens come race season too because if the track performances of the European newcomers does not live up to the past couple years of anticipation and hype, I do not see them doing well in general consumer sales. Just my opinion anyway.
Pricing won't make it a niche bike, it's limited production will. Ducati doesn't make many bikes per year - even though they are owned by VW they are essentially a small company. Ducati started building bikes around the same year as Honda. The year Ducati built bike number 1 million, Honda built bike number 300 million. The Ducati will cost around 15% more than a Honda and they'll sell every one of them they make. Which won't be many.
@@DezmoDog the reason I put it in a niche bike category is because of what it costs to make a modern interpretation of a KX or CR 500 using the latest chassis and updated engine tech. It was close to 15k to build a Service Honda CR 500 AF spec’d out almost 10 years ago and they are a very niche bike and like you mentioned low production numbers for the Ducati would be the main factor but from my standpoint the pricing also factors in because it limits who can feasibly access the units. 16 to 17k for an MX bike is a lot of money if you are an independent amateur rider or simply a weekend warrior hobbyist. Just saying.
It will be exciting to see the results on the track. It looks like it could be very competitive.
Actually, Desmodronic was refined in the late 1930’s in the airplane industry, Originally designed in the 1890’s but not really used due to lack of ability to properly heat treat parts yet. First started being used in WW2 by the Swiss and Germans.
Hard not to be excited. Good video presentation too. 😊
Too bad Aprilia left the train. With the MXV they had figured out most of the problems.
Also if you do the known updates/ upgrades to your XV it will last without a problem as long as an EXC.
It's factually not true that the Desmodromic system has no springs. It's just that the springs are there to keep the rocker against the cam lobe, instead of having to close the valve. There is definitely resistance when you try to turn the cam shafts on these heads.
rode a 900 SS desmo v-2...wow!...Phil Shiling, an ex editor of cycle world magazine had a race team on 900 ducati desmo's...they did a bunch of improvements and seems i remember those Vtwins spinning at 14,000 rpm!
The valve train in a modern 4 stroke is not what limits the revs. Valve spring motors are capable of revving just as high as Desmo.
the desmo sound is crisp. a lil humm sound out the back. im anxious to see it in a pack
Forget the Ducati, I want that TMR YZ125 in the background!
Technically, they usually have a really light spring for a little extra tension.
Just to let you know that the Ducati desmo valve train has been designed That way so the Engine can Rev more than engines with Springs engines with Springs can suffer valve bounce at high revs. Therefore, the Ducati is designed to rev more And deliver more power good video. Thanks
Looks awesome, I can't wait to see about getting on the list to order one.
Love your clips mate! just wondering with the frame/head stem being one piece, obviously a forged piece, gee if they want to change any characteristics(?) of flex etc that would mean a whole new die? not as easy or cheap to change any minor detail issues? maybe thats why they are not going into production for a while, they would want to get this rigity/flexability correct? just a thought, keep up your great work! cheers from Australia
The 1955 W196 Mercedes F1 and 300SLR both had desmodromic valves.
First of all I like the style even that front fender they are using. That makes them unique & very Ducati like bike. Everything you have said are good & made for performance. Although without any MX race under their belt. I'm sure of the components might a bit change if they can find some more performance in some areas.
Anyway we we'll see. They have got two great riders who develops this MX bike.
I think all the plastic designers come from the "Batman school of abstract art" college. Abstract art has no place on my functional dirt bike. You can keep the bat wings and arrow tips,---what ever they are for. I replaced my front fender with an older model, and went "Ronnie Mac" on the rest of the cartoon plastic. Looks great.
What are those wings for anyway? The artist does not even know.
I disagree about the front fender looks cool and it’s a reinforcement for strength. I think of some of the early ktm fenders would flap around more then normal. Ducati will stay nice and firm, also good aesthetic. I hope they keep it just like that. Would love to ride one I rode mostly Hondas and Yamahas that me started in street ducatis would love to ride mx on one.
In motocross the design of the bike has reached a sweet spot years ago. Power is not the issue, nor torque. Its is traction and suspension, and even there, it is the ability of the team and rider to fine adjust for the circumstances what makes the winner. And the biggest part of succes is the talent of the rider. The bike is not that important anymore. That makes the sport so nice and competitive, unlike formula 1 where you never can win without a big budget.
By the way, the desmo system that Ducati uses is to avoid "valve floating" at high rpm. Motoscross bikes not running at very high rpm's. It has also disadvantages, one is a heavier construction, more mass to accelerate. If all of these design choices you talk about would be so much better, the other brands would allready have applied them, they are not stupid.
And there are no "best" brands, only better products, that come with a higher price.
Look at the Koenigsegg car engine. It has pneumatic valves and computer timing. Zero friction engine rotation.
This would be necessary if petrol engines are to keep up with electric.
I think it looks awesome and I'm sure it's gonna perform as well
Yeah , and comes at a good price to I bet ya ,because it’s a Ducati but I do like the specs and the looks but no sale from me !
Watch Ducati force a rule change in professional racing if this engine lives up to its potential. Desmo tech is proven, and I can’t imagine how high a 250 could rev. God bless Italy, and welcome to the world of off-road
Well it sounds competitive. Is it really one of the lighter bikes? Does it really have the most power and by how much? Most all the top bikes in this class have all the top shelf stuff to go with. Lets wait and see about results and reliability, handling, etc..
So here in 2024 when valve float is somewhat a thing of the past so why desmo? The system requires minimal hp to open the valves and mainly you can run a very radical cam profile without skip or float.
BTW Taglioni went with the desmo system that Mercedes had perfected at the time (1950s).
I just bought the hypermotard 698 and I love it!! Very fast too.
With no valve float from having no springs that thing should have a super high redline?
Just got a promotion at work. The Italians have some serious timing
Would like to know valve adjustment intervals and if they will come out with a desmo 250…
In my experience Shaow is just a bit better than KYB. KYB does a better job with R&D testing settings but component wise I prefer Showa.
Another very well edited video! Thanks !
Another great video, Rado! Thanks for the info
Can't wait to get mine when is available in Mexico !
Probably be 20 grand!
Prices are out of control.
Lets hope the 450 supermoto follows.
Will rev to the moon. Less friction and no valve float 😊
Quite surprised they did not go with Ohlins for their suspension.
Looks exciting, great quality,
Mousse Balls!
You don't know!!! You are Dreaming!
I think you misspoke. Maybe most powerful single cylinder 4 stroke. That does not include 2 strokes. 2 strokes cc for cc will always be more powerful still.
Great video.Exsplained very well.
Another great competitor in the market
Couldn't agree more!
you forgott the 3th red bike, Fantic 😂
sounding great. What is the hp
Yeah I want one for sure.
Add 20lbs of mud to the bike with the giant shovel for a fender, other than that bike looks sick🏁🤙
Hope they one day drop a 350
The head is very tall, and I measure from the photo that it may be the tallest bike in seat height. That is not a plus in MX, but MXA has accepted tall bikes.
So will we,---again. I have never seen so many amateurs (go-pros still allowed for amateurs), so slow in corners.
can't wait for enduro version
im so excited that Ducati has a dirt bike my buddys and i cant wait thats all we are talking about can you tell we are Italian 🤣🤣😂
whats up with the Beta logo on the swingarm?
Had the same question. Beta tools. No relation to Beta motorcycles.
They mastered it.....
Honda had that on their 450 strret bike in the 1960s
No valve Springs cool Iam sure it still has valve adjustments
Its great to have more OEMs on the circuit.
But....do they all have to be backed by Monster???
First Kawi, now Yammie.
Now it appears that Ducati will be Monster backed.
How long before Monster absorbes Suzuki?
Monster already backs Honda, in rally raid, and Baja.
So... the clock is ticking on "Monster Honda" backing.
I get that Red Bull KTM, and GasGas is a thing.
Red Bull used to be a big thing in outdoors, but no more.
Rockstar Husky is a minor player now .
Our group started a drinking game, a few years ago..."take a shot every time Lee Doofus, or RC say Monster Energy".
....none of us were conscious at the first 250 heat gate drop!!!
Well I like it❤but the price tag probably unreachable for the average rider
Impressive power for a 650 single in 2024, just a smidge over the 75hp from Ducati in 1993 from their 550 supermono.
I will have one of these.
Can you put a sound clip at the beginning of the clip next time? lol Thanks!
wow it looks like there might be a quad on the right hand side
This is definitely a totally new bike and it being a Ducati you can be certain they paid attention to detail. I think I’ll wait until they get a little cheaper though. Lol
Put an electric waterpump in there and you have even less drag in the engine. 😅
If it's anything like other DUCATI full rebuild after a day out , if it doesn't break down before on the day.
Italy is in fire
Respectfully i would rather see tm step up and build bikes for ama. Its like ducati is cutting in line
Hello from America 🇺🇸 I want this bike
Ducati coming to motocross is even better than Triumph
All of their bikes are normal “full-on” beasts. Absolutely no “valve-float” with the Desmo valve train. Bet the motor makes 15 -20% more power than other brands.
And never forget the hard fought lessons Ducati went through developing a frame riders could win with in Moto GP.
That brake pedal design is already done by Stark on the Varg. Ducati not the first.
I dont get whats the difference on the brakepedal from ducati is to the other bikes
Cash poor Stark will be cast on the EV dead pile within 3 years ….bet me?… or the Chinese buy them…
@@CoolioDaMan yeah, sure. 20 grand? Should cover a new bike of my choice in 3 years.
@@danielseibert4082 Pedal goes behind the frame instead of outside like on all other bikes.
@@Marleysdad808 there are at least 4 other brands that have the pedal behind the frame
So. My issues with Ducati, is one, here in Melbourne, there’s only three dealers, so it’s a pain in the arse if you need anything “factory” done. Two, you only get 2 year’s warranty and roadside assist- you need to buy an extended warranty, of only 12 or 24 months, so for a prestige manufacturer that’s really unacceptable. BMW gives you 5 years and 3 years roadside IN THE PRICE! Three, some stupid design decisions - why on earth do they shove the air filter under the tank on the Desert X? It’s an hour and a half to get the tank off. Imagine you’re in the desert, on an extended trip, and you need to check it…! And it requires 185nm of force on the rear axle nut! So when you do chain tension, or need to put an emergency tube in, you need to carry a long handled spanner to get it off, or one that breaks down into pieces. Really, really stupid.
I want one. Looks sick
DesmoDROMIC, not DesmoTRONIC 😂😂😂
In any case I think you missed an important point: the single frame is another trademark from Ducati. All their sport bikes have the single frame, from MotoGp to Panigale V4.
I believe Cagiva also runs the rear brake lever behind the frame. But I would rather you have been a salesman for Cannodale 24 years ago, because they did not take anybodies money to make a launch bike into electric. I think we get dumber every generation since the 60's, and I don't think it is an accident.
"DESMO POWER"!!!! 👍
Desmo valves could be interesting.
