Ducati Diavel V4 RS is a limited-edition version of its power cruiser that now claims the title of fastest-accelerating production bike in the company’s line-up. The Diavel V4 RS joins the Multistrada V4 RS, expanding the exclusive RS range that brings MotoGP-derived technology to Ducati’s street bikes. The Diavel V4 RS isn’t simply a standard Diavel with sportier graphics. For starters, Ducati engineers have swapped the 1,158cc V4 Granturismo engine from the standard Diavel V4 for the 1,103cc Desmosedici Stradale engine from the Panigale V4. As a result, peak output figures stand at 182hp at 11,750rpm and 120Nm at 9,500rpm – up 14hp but down 6Nm compared to the standard Diavel V4. Performance claims are equally impressive. In the hands of Marc Marquez, the Diavel V4 RS achieved a 0-100kph sprint in just 2.5 seconds, making it the fastest-accelerating road-going Ducati yet. The bike also debuts a new Ducati Power Launch system with three selectable levels that manage torque delivery and traction for optimal acceleration. Ducati says this allows even amateur riders to achieve similarly quick launch times. Ducati has equipped the Diavel V4 RS with extensive carbon-fibre components, including front and rear mudguards, front fairing, tank covers, tail fairing and air intake ducts. A lighter battery also contributes to weight savings, with the RS tipping the scales at 220kg, 3kg lighter than the standard Diavel V4.
