ENGINE

The Ducati Desmosedici RR features the most advanced technology and aerodynamics derived directly from the GP6 raced in the 2006 MotoGP World Championship. The engine of the Desmosedici RR accurately reflects that of the MotoGP bike. Ducati’s traditional Desmodromic system guarantees precise valve control at the very highest revs and is the perfect application for the 989cc, four titanium valves per cylinder, L-Four layout. This awesome powerplant, which is prepared in asymmetrical Twin Pulse configuration, is a masterwork of precision engineering.

The double overhead cams are gear driven, a sophisticated and reliable solution that enables precise valve timing in all conditions. This authentic copy of the GP engine is further endorsed by the use of a cassette type six-speed gearbox and hydraulically actuated dry multi-plate slipper clutch.

The aim of producing a light but robust engine has led not only to component design of an unrivalled quality, but also the use of exclusive racing-derived materials including sand-cast aluminium crankcase and cylinder heads, titanium connecting rods and valves and sand-cast magnesium engine covers.

















A Magneti Marelli 5SM ECU and high-speed CAN line electronics have been employed for the highly sophisticated management required for the four 50mm Magneti Marelli throttle bodies and 12-hole ‘microjet’ injectors feeding the powerful four-cylinder engine.
An all-time ‘first’ comes with the use of a 4-2-1 exhaust system, with ‘vertical exit’ silencer, hidden in the tail-piece. These are the benchmark performance features for a MotoGP replica bike which is capable of delivering more than 200hp when used with the 102dB racing muffler and dedicated CPU race kit. Amazingly the Desmosedici RR with its catalytic oxygen sensor exhaust, homologated for road use, fully complies with Euro 3 emission regulations.
