    • The V4 Granturismo has been developed for maximum smoothness of operation and has record-breaking maintenance intervals
    • Compact and light, performing, featuring rich torque values: an engine designed for “adventouring” use, at the same time able to offer great thrills and sportiness
    Borgo Panigale (Bologna, Italy), 15 October 2020 – A new era begins in Borgo Panigale as Ducati presents to the public the new V4 Granturismo, the engine that will equip the long-awaited new generation of Ducati Multistrada, which is going to be unveiled on Wednesday 4 November.

    An extremely compact, lightweight, high-performance, torque-rich engine designed to meet the needs required in “adventouring” use without neglecting emotion and sportiness.

    Built with latest-generation technology as well as first-in-class materials available, in order to guarantee both durability and reliability, the V4 Granturismo stands out for its record-braking maintenance intervals for a motorcycle engine and has been created as the heart of a high-performance and dynamic bike, ready to explore every corner of the planet with its owner.

    The engine was presented to the public with a video in which Claudio Domenicali - Ducati CEO - and the engineers and technicians who followed its development reveal all its secrets and features to the Ducati enthusiasts.

    Every single technical choice made during the development of the V4 Granturismo project have the aim of ensuring maximum fluidity of operation combined with a substantial extension of maintenance intervals.

    The new distribution includes a spring valve return system, that brings the maintenance intervals of the V4 Granturismo to 60,000 km. Figures obtained thanks to the in-depth expertise Ducati acquired in the use of materials, treatments and technical solutions developed around the Desmodromic system. All this, applied to a spring valve return system which stresses less the components if compared to the Desmo, brought to set an outstanding milestone never set before by a motorcycle engine. In addition, the engine ensures great regularity of operation at low revs and low loads, without forgetting the outright performance, the power at high revs and the reach of an authentic sports engine: The V4 Granturismo delivers 125 kW (170 hp) of power at 10,500 rpm, and a maximum torque of 125 Nm (12.7 Kgm) at 8,750 rpm. All this respecting the stringent Euro 5 homologation norms.

    With its 66.7 kg of weight, the V4 Granturismo can boast a record lightness, being 1,2 kg lighter than the Testastretta twin-cylinder used on the previous Multistrada 1260. The 1,158 cc displacement came out as being the perfect point of connection in terms of performance, lightness and dimension of a V4 engine, capable of being incredibly light and compact. Compared to the previous generation engine, the V4 Granturismo results 85mm shorter, 95mm lower and only 20mm wider. This compact layout allowed Ducati engineers to house the engine in the frame more effectively and centrally in order to positively influence the position of the bike's center of gravity, with all the resulting benefits.

    The V4 Granturismo also inherits some elements derived from the experience gained by Ducati in the racing world, such as the decision to adopt a counter-rotating crankshaft, which improves the handling and agility of the bike, and to exploit the "Twin Pulse" technology, capable of offering a full-bodied but perfectly manageable power delivery at every speed.

    To avoid a drop in thermal comfort due to the heat transmitted by the rear cylinders, the V4 Granturismo adopts the strategy of deactivating the rear bank at idle. In this way, when the bike is stationary, the combustion process in the cylinders is halted and this improves the thermal comfort of the rider and passenger thanks to the lowering of temperatures while simultaneously reducing fuel consumption.

  1. No Desmo...........no Ducati .......

  2. Speaking as someone who has owned a 1100 V4 Tuono and came back to a L twin it's a no from me. But we all got to be different to make the world go round...

  3. No Desmo, no twin, no single sided swing arm the only thing making it an Audi, sorry Ducati is the price yes?
     
    • Agree Agree x 4
  4. I assume from a sales perspective this makes the Multistrada even more 'suitable' for a vast majority of touring-bike riders from other brands. I've had several customers who bought an S1000XR caused by the MTS 1260 very-low rev range shocking character.

    Offcourse we all know to pull the clutch if rpm's are lower than 3000... ;)

    It can also be said that the inner-roots of Ducati are more lost. However.. It's a technical marvel isn't it :)

  5. I bet it’s an unbelievable bike, stop being luddites

  6. Nah, I dont think so. Volvo's can be quite fast too...but they are still Volvo's :D

  7. Looks great to me, just a little surprised it's (only) 170bhp.
     
  8. If they’d put this engine in the Streetfighter I’d have been more inclined to buy one,...it’s got more grunt where you need it !

  9. It wouldn’t bother me that springs were returning my valves rather than a closing rocker and cam.
     
  10. 'Deactivating rear bank' - hasn't that been a standard feature since the 70's?

  12. No Desmo means 60K valve service intervals.
     
    • Agree Agree x 1
  13. I bet that’s dreadful to ride though
     
  14. and no desmo service £££
     
  15. Thank christ they've finally made the decision to develop a modern bike without Desmo ! .... I guess they could keep it on the sport models. I wouldn't be surprised if this is the beginning of the end for Desmo on Ducati road bikes. All a bit late though if you ask me..
     
  16. Not at all, I mean it's a 45 year old bike and the brakes are nothing to shout about but it's a glorious old thing, torquey and not at all any the worse for having a spring return on the valves rather than a mechanical closing method. Clutch is a bit heavy, if we're being really picky... but then that's what strong hands / forearms are for.

    Desmo doesn't determine valve train performance until very high revs, where it becomes a benefit as the valve timing can be more precise and less susceptible to spring performance. Kind of moot these days though as spring technology has for the main part advanced sufficiently well. Most of the engine characteristics of a Ducati can be attributed to its configuration, and the V4 was already a significant departure from the preceding twins.

    Mind you, I'm sure that people got upset when Ducati started making twins rather than singles, and went watercooled with the 851... progress is progress.

  17. Wonder what the heat is going to be like. It has deactivating rear cylinders so I’m guessing
    H. O. T.
    Ok on a sports bike I think but on a Multi, if it runs as hot as the Panigale that could be a big issue.
