Why ONLY Ducati Uses This Part To Go Fast

Thanks to Morning Brew for sponsoring today’s video! Become smarter in 5 minutes by signing up for free today:

Nothing sounds cooler than a higher revving engine. An s2000 at 9000rpm, or a rotary engine at 10,000 are pretty sweet. But those are push-over numbers compared to what Ducati can do. In the 4cyl Panigale they're making 17,000rpm and they doing with technology from 1950s F1. It's called a Desmodromic Valve system. So how does this tech thats older than the consumer microwave out rev modern 4cyl in cars today? And why does no one else use it? Today on B2B we're gonna find out!

We'd like to thank our friends at Ducati for their help with this episode.

    While the Desmotronic information in this video is factual, there's only a couple of bikes in the Ducati line up in 2021 that even have a Desmo valvetrain anymore. Furthermore, the Monster you keep showing over and over isn't one of them, its uses springs. Why? because in Volkswagen/Ducati's wisdom to have bikes with greater mass appeal they had to increase the expensive service intervals to be more competitive with Asian manufacturers to gain younger customers. Do I agree with Ducati dismantling everything that made them distinctive like dry clutches, Desmo exhaust notes and trellis frames in the name of mainstream appeal? no. Bottom line, Ducati is an enthusiast motorcycle, period; and enthusiasts except what comes with it in the same way exotic car owners understand the reality of ownership.

    I like how Jeremiah can laugh at his early work on Donut. It was definitely cringe worthy. Now look at him. I love watching his show. It kinda reminds me of when I started playing guitar and singing. Everybody told me “shut up Kyle, you’re going nowhere”. Now, when I sing and play, people say “don’t quit your day job”. Progress.

    That's what makes them sound like a coffee can full of nuts and bolts being shaken rapidly. I like the Koenigsegg solution, camless engine. Look it up if you want to be amazed. I actually thought of that design when I was learning auto mechanics in my late teen to early 20 years but didn't have the technical knowledge to design a solenoid that could pull it off. I even went a step further with the idea than they did (well, in a different direction) because I had the idea to make the cam profile adjustable by the driver. If you wanted power mode, you press a button for race cam, if you wanted mileage mode, you press a button for mileage cam, if you want torque...and so on. What I mean by a different direction, they went a way that I never thought about, which is super cool. They control each valve of a four valve per cylinder design independently of each other so they can control combustion swirl in the chamber and other things like EGR or I suppose (but don't know if they do it) they could make it mimic an Atkins cycle engine.

    I'm just at the beginning of the video and it's implying that you need desmodromic valves to get high RPM motors. The Japanese have been cranking out straight four cylinder motors for a long time that reach 15K+ rpms forever. Desmodromic valves are just Ducati's thing, but totally unnecessary if all you're concerned with is getting a high revving motor.

    My boss developed the 1991 Ferrari F1 V-12. I asked him why no desmo, he replied they lost 50 hp to parasitic valvetrain drag. At the Ferrari museum in Modena, the desmo head from that era is on display. I suspect ducati sticks with it to sell bikes mainly.

    You totally missed the point that Ducati had to stick to the desmo technology because of their adherence to 2 cylinder design (until recently...). A 4 cylinder equivalent has much smaller and more light weight valves and consequently less inertia and doesn't need desmo's to rev the engine sufficiently to squeeze out the desired power.

    Desmodromics make for the best valve train, period. They are found from entry level Ducatis, to their top MotoGP bike. No other valve train can do that. Others use pneumatic valves on their MotoGP bikes. And which bikes are the fastest due to the most powerful engines in MotoGP? The Ducati desmodromic ones. Yes, they need greater attention and higher costs to service, because there are 2 shims for every valve, but if you want MotoGP tech in your bike, you pay the price for the best.

    Theyre getting away from it now in racing engines and the V4 Grandturismo as its too complicated and offers no benefits over a PROPERLY setup valvetrain as they have said. Its a cool leftover 1970s remnant to compensate for lack of valvetrain tech, metallurgy, and knowledge. Yamaha had a 16,000 rpm valve sprung motorcycle in the 1980s and F! cars go to 20,000+rpm with them

    Unfortunately all this complexity of the desmo system is outdated. Ducati's V4 doesn't use it. Improvements in design and metallurgy made it an outdated design a couple of decades ago. Ducati stayed with it as part of Brand marketing, causing excessively high $ maintenance costs.
