Someone put a Ferrari V8 in a motorcycle

It’s Got 400 Horsepower

Los Angeles-based custom motorcycle builder Maxwell Hazan has built a bike powered by the V8 engine from a Ferrari F355. Dubbed the HF355, it’s been in the works since early 2024, and still isn’t quite finished, but recently turned a wheel for the first time.

“The goal was to create a V8-powered sport bike that still had the proportions of a normal motorcycle and it was definitely a challenge,” Hazan said in an Instagram post first spotted by Hagerty.

Motorcycles with large car engines have been built before—perhaps most famously by Dodge, which stuffed a Viper V10 into its Tomahawk concept bike—but that doesn’t mean the task has gotten any easier.

Hazan built a custom frame to house the Ferrari engine and a six-speed transmission, shrouded in handmade bodywork, with brakes and suspension capable of handling the engine’s estimated 400 horsepower. That’s pushing just 590 pounds of weight with fluids and four gallons of gasoline onboard. The engine and transmission make up 319 pounds of that total.

A former interior designer and contractor, Hazan began building motorcycles in his father’s woodshed in Brooklyn, before moving to L.A. and going into the bike-building business full time with his own company, Hazan Motorworks. His previous builds include an eclectic mix of customized classics such as BSA and Vincent, some more modern designs, and a salt-flats racer dubbed the Salt Shaker. But the Ferrari-powered HF355 might be Hazan’s most distinctive build yet.
