Ducati explodes Multistrada V4
Not literally, but images of the engine in a million pieces show that the four-pot engine powering the forthcoming Multistrada V4 does without a desmodromic valvetrain. Shocking, right?
Not really, because while peak revs are down from around 14,000 to just 12,000, valve clearance service intervals are up to a staggering 60,000km thanks to the spring-valve system not needing as much adjustment.
The new mill is known as the V4 Granturismo, and it is based on the Stradale engine powering Panigale V4 and Streetfighter V4.
The V4 Granturismo engine displaces 1158cc (83 x 53.5mm), and generates a maximum of 168hp (125kW) at 10,500rpm, and peak torque of 125Nm at 8750rpm. It is Euro 5 emissions compliant.
It also features displacement on demand, the rear cylinder bank taking time out when needed to manage heat build-up, fuel consumption or both.
Not only is the new engine lighter than the Testastretta V-twin DS motor it replaces but it is also more compact, a good trick for a four over a twin, the only dimension increasing being width. Even then it is only 2cm more.
The engine weighs in at 66.7kg.
Other features of the V4 GT include a counter-rotating crankshaft, close-ratio six-speed transmission, and an up/down quickshifter.
The Multistrada V4 officially unveils in about a fortnight.
