TMC Dumont Is a Motorcycle with an Airplane Engine (and Giant Wheels)

When you’re a retired Formula One driver, what else can you do in your free time except build mind-bending concept motorcycles? In the case of Tarso Marques of Brazil, that’s exactly what he’s doing with the insane TMC Dumont motorcycle.

Yes, it’s still a concept so, no, you can’t drive it yet. In fact, you might be wondering how it even works because the construction shouldn’t make sense in real life.

This hub-less bike swaps a traditional car engine for a 1960s Rolls-Royce aircraft engine, creating an absolutely sick design with a body aesthetic that is futuristic, svelt, and should definitely be in the next 007 movie.

Anatomically, the aircraft engine is positioned where a standard motorcycle engine and fuel tank would be, but takes up an enormous amount of space. Basically, as much as a full frame, radiator —the works. The massive 36-inch wheels are essentially spoke-less and completely open in the center, so with the 300-horsepower engine, we’re hoping the brake disk and caliper have something to hold on to … because we can’t see it.

Based on the low-riding profile of the seat and engine, it’s questionable how the bike could sit above the ground, but it does. At least, the concept does. Just pray for a road without speed bumps.

Some motorcycle enthusiasts have questioned the safety and turning abilities that would result from having the back “wheel” so close to the rider — hello, wedgie or mega backside tire burn — and have called the bike “impractical.” That being said, TMC Dumont drove away with the “Best of Show” award at the 2018 Daytona Bike Week.

This isn’t the first time a motorcycle fanatic has strapped an airplane engine to their hog. Back in 2013, the Red Baron bike featured the 150-horsepower, nine-cylinder Rotec Radial engine used in WWI-era planes. However, in terms of pure looks, we’ve never seen anything like TMC Dumont. The motorcycle has been compared to everything from a piece of art to a Tron bike — ultra-sleek, and record-breaking.

Previewing the other passion projects Marques is developing with his brand Tarso Marques Concepts makes us mildly jealous, somewhat shook, and overall excited to finally get back out on a bike.

Why another LiveWire S2 model?

This model's 17-inch wheels and tires distinguish it from the Se Del Mar, which has 19-inch wheels and tires, is LiveWire's street tracker model.

Keeway America, which established a dealership network for Benelli motorcycles and Keeway scooters, announced a new partnership with Benda Motorcycles.

The first Benda motorcycles in the U.S. will be the Chinchilla 300, the Chinchilla 500, and the Napoleonbob 500.
The Benda brand story

According to Keeway, Benda Motorcycles blends "radical aesthetics with state-of-the-art engineering." The Benda bikes have liquid-cooled engines with carbon fiber drive belts, LED lighting, and standard ABS braking. The gas motors are smaller and less potent than Harley-Davidson and Indian Motorcycles V-twins. They are intended for entry-level riders who primarily ride in small towns and back roads.

Royal Enfield tantalizes with Flying Flea electric motorcycle
The new Flying Fleas will be built for urban use, not battlefields
Royal Enfield Flying Flea C6 concept.

Royal Enfield recently introduced Flying Flea, a new division that develops and manufactures electric motorcycles. The first production model, the FF-C6, is expected in early 2026. The final version will look similar to the prototypes in the photos, which have already been in development for several years. A scrambler-style model will follow the FF-C6.

Established in 1901, Royal Enfield is best known today for relatively low-cost, heritage-focused motorcycles with small-to-medium-displacement gas engines. Flying Flea is a forward-looking brand, but it, too, has roots in the company's history. The original Flying Flea was a lightweight but rugged small motorcycle that was airlifted and dropped by parachute to British Special Forces personnel on WWII battlefields.
