Ducati ditches Desmo for the V4 Granturismo and that is an enormous deal – Roadshow


Ducati is legendary for lots of issues. It builds daring, thrilling motorcycles that make nice noises and experience like nothing else, however it’s additionally well-known for its dogged dedication to one thing known as desmodromic valve actuation, or as Ducatisti name it: Desmo. It has been part of the Ducati model’s DNA for the reason that late 1950s, and it might be actually bizarre if the corporate determined to make a motor with out it, hastily.

Solely, that is exactly what it did. Ducati introduced on Thursday that its forthcoming V4 Granturismo engine, which will likely be fitted first to the brand new Multistrada V4, will use typical valve springs to manage closure on each consumption and exhaust valves.

Now, to know why this can be a massive deal, we must always in all probability return in time to the late ’50s when Ducati began to make use of the tech within the first place. See, metallurgy again then wasn’t as refined as it’s now, and bikes have been having points with valve springs sporting out and breaking, notably at excessive revs. Ducati’s engineers figured that if it needed to make high-revving race engines that may final, it ought to discover a higher technique of closing the engine’s valves.

After all, Ducati did not invent desmodromic valves. They’d been round for some time — Mercedes was an enormous proponent of the tech in its racing engines within the first half of the 20th century; the 300SLR race automotive used them in its straight-Eight engine, for instance. Anyway, the choice proved to be a superb one for Ducati as a result of it started successful races by the bushel quickly after.

This seems sophisticated, and it form of is, however it might be a factor of the previous for Ducati.

Quick ahead 70 years, and valve spring expertise is far more superior. It is now potential for even comparatively cheap client bikes to rev out to 14,000-15,000 rpm with no points. The actual fact is that Desmo is simply not obligatory past the heritage argument. So, in an effort to increase service intervals (one thing that Ducati could be very eager on doing, generally, lately), the engineers for the V4 Granturismo moved to conventional poppet valves with spring closure.

So, past the valvetrain, what makes the V4 Granturismo cool or particular? Effectively, to begin, it isn’t solely extra compact in nearly each dimension than the 1260 L-twin it replaces (other than being 20mm wider), it is also lighter and smoother. That compactness additionally helps engineers optimize the Multistrada’s chassis traits to make for a extra snug, higher dealing with motorbike (in idea, no person has ridden it but).

The V4 Granturismo produces round 170 horsepower and 92 pound-feet of torque, numbers which are similar to the marginally larger-displacement L-twin at present discovered within the top-tier Multistrada. It is a win-win state of affairs in sensible phrases, however will probably be fascinating to see how Ducati followers react to the brand new, Desmo-less engine. Will it sound completely different? Will it really feel completely different?

We’ll have to attend and see, however Ducati additionally launched a number of different options that may assist with quality-of-life. Most notable is the usage of rear-cylinder deactivation. This could assist cut back the quantity of warmth thrown on the rider and passenger when the bike is at or near idle — one thing that Ducatis have traditionally struggled with. It is also acquired the identical counter-rotating crankshaft design because the V4 within the Streetfighter and Panigale fashions, which helps with dealing with and makes the bike much less more likely to yank up a entrance wheel with out being provoked.

We’re very excited to throw a leg over this new Multi, particularly with the inclusion of adaptive cruise control and blind-spot warning systems, which we lined earlier. Control Roadshow for our assessment of the Multistrada V4 when it debuts.
