This Futuristic Motorcycle Paired Sci-Fi Design With An Airplane Engine – SlashGear

Marques was reticent to use a run-of-the-mill V-Twin or a two or four-stroke single-cylinder engine. He wanted something altogether … more. 

When he stumbled onto a 300-horsepower Rolls-Royce Continental aircraft engine, his team finished construction of the bike a mere seven months later.  Marques showed it off at Daytona Beach Bike Week in 2018 and ended up taking home several “Best of Show” wards.

The specs for the Dumont’s engine aren’t listed on the Tarso Marques Concept website, and few details can be found elsewhere. After comparing images of the Dumont’s powerplant with photographs of Continental engines, it appears to be one from the company’s Tiara line. More specifically, either the O-405 (285-320 horsepower), the O-520 (320-hp), the O-526 (270-310 horsepower), or the IO-550 (280-360). No other Rolls-Royce Continental airplane engine is capable of, at least stock and in 6-cylinder format, banging out 300 horsepower, as stated by so many reports.

According to the Robb Report, Marques said, “Every single piece was a challenge, but I knew that the concept would work perfectly.” And he was right. What there is of the bike’s low-slung minimalist body is made of carbon fiber and aluminum. The 36-inch hubless wheels make the Dumont appear as if it’s floating along the road, ala some futuristic vehicle we’d love to ride.
