Ducati Desmosedici RR Review

It doesn’t take long to be intimidated by the outrageous Desmosedici RR. If the stratospheric $72.5K price tag doesn’t get you, the menacing mechanical cacophony upon start-up will. Observers are sucker-punched straight into the gut, and the beautiful racket portends an experience unlike any production streetbike in the world.

It’s quite incredible that a manufacturer has offered such a repli-racer to the public. The D16RR is literally a MotoGP bike built for the street. And not those scrawny 800cc prototype racers currently on the grids – we’re talking the big-gun near-liter-sized versions. As such, the RR carries a compact 989cc V-Four engine inside a version of Ducati’s trademark tubular-steel trellis frames.


The engine itself is a jewel. It features the same bore and stroke measurements (86.0mm x 42.56mm) as those on Ducati’s 2006 racebike, the D16GP6. It uses the “Twin-Pulse” firing order in which the crankpins are offset by 70 degrees (cylinders fire at 0°, 90°, 290° and 380°) to generate what Ducati terms as “soft pulse timing.”

No soft pulses are felt from the D16’s saddle – this thing snorts and sprints around a racetrack like a rampaging demon, as we found out during a few lapping sessions at Willow Springs Raceway.

Our test unit was equipped with the race ECU and exhaust system included with each Desmosedici, a no-brainer swap for the standard street exhaust. So equipped, it is said to achieve the magic 200-horsepower mark at 13,800 rpm when measured at the crankshaft. As for rear-wheel power numbers, those who have had it on a Dynojet dyno say it’s pushing nearly 180 hp. Peak crankshaft torque of 85.3 ft-lbs arrives way up at 10,500 rpm.

When a motorcycle has a retail price that compares unfavorably with a rural home in Iowa, it makes one wonder why it costs so much.

Here’s a partial list of the many high-end components on the luscious Desmosedici RR.

  • Sand-cast aluminum crankcases and cylinder heads
  • One-piece forged steel crankshaft (MSRP: $11,000)
  • Sand-cast magnesium cam-drive cover and alternator casing
  • Pressure die-cast magnesium-alloy oil sump, cam covers and clutch cover
  • Titanium connecting rods
  • Titanium intake and exhaust valves with CrN (chromium nitride) coating
  • Marchesini forged and machined magnesium wheels (MSRP: $18,500)
  • Specially developed Bridgestone tires, with tread pattern, construction and profile unique to the D16RR, including the oddball (but GP-accurate) 16.0-inch rear
  • Öhlins 43mm FG353P pressurized fork with TiN-coated sliders
  • Öhlins shock with rebound, low/high speed compression adjustment and hydraulic preload adjustment
  • Brembo monoblock (one-piece) front brake calipers and 330mm rotors (same spec as used in rainy MotoGP races) with radial master cylinder and remote (left handlebar) adjuster
  • Carbon fiber subframe and bodywork
