Ducati couldn’t have chosen a better time to launch its Desmosedici RR, the road version of 990 cc GP6 MotoGP bike. The massive valves-all sixteen of them- are controlled desmodromically rather than by springs. The crankpins are staggered 70 degrees apart, giving firing intervals that produces what Ducati calls a Twin Pulse firing order. This gives the best balance between drive and traction. The wide, shallow pistons have two compression rings instead of the GP6’s single ring, but are identical in every other respect. The connecting rods and valves are titanium, and a Magneti Marelli ECU controls the ignition and fuelling. Although it doesn’t features the traction control or the ride-by-wire of the MotoGP bike, the technology on the tap is enough to produce 195 bhp or more than 200 bhp when equipped with the race exhaust supplied with the bike.
