Ducati Desmosedici RR vs. 1098R - Money No Object

When Only The Best Will Do

Hard Parts

Engine
A blast from the MotoGP past, when men were men and racebikes displaced 990cc. Dimensionally identical to the GP6 racer, the 90-degree V-4 maintains the irregular, "Twin-Pulse" firing order (0/90/290/380-degree sequence). The 16 valves are desmodromically actuated (thus the name), the cams are gear-driven and materials are exotic: magnesium case covers, titanium valves and con-rods.

Chassis
It wouldn't be a Ducati without a steel-trellis frame, paired with a carbon-fiber subframe. Built from four different sizes of tubing, the RR frame is 80 percent (!) stiffer torsionally than the 1098, and employs the engine as a stressed member. The massive aluminum swingarm, which pivots in the engine cases, is "only" 35 percent stiffer than the 1098's single-sided arm.

Suspension
Suspension comes straight from the MotoGP paddock. This is the first production streetbike with pressurized fork damping, housed in remote reservoirs on each hlins leg. The Ohlins shock under the swingarm offers a dizzying array of adjustments: 20 low-speed compression settings, 48 high-speed positions and 25 clicks for rebound damping.

Brakes
Another first for a production streetbike: A race-style remote adjuster for the front radial master cylinder allows the rider to adjust brake-lever travel on the fly via a knob located above the left clip-on. Brembo Monobloc calipers and 330mm rotors are identical to those on the 1098R-and just as impressive.

Dyno
The Desmosedici's 989cc V-4 was designed to perform wide-open on the racetrack, so the steep, top end-biased dyno trace is no surprise. The 1098R makes more peak torque, but the D16 makes more than enough-over 70 lb.-ft. between 9000 and 14,000 rpm-and spreads it over a much broader range.

Ergos
Ergonomically speaking, the Desmosedici RR is almost identical to the 1098R. The D16's bars are lower and its pegs are higher, though both are within a half-inch. A wider frame (to accommodate the V-4 motor) and a bigger, 5.7-gallon fuel tank make the Desmo feel larger from the saddle.
