A street-legal motorcycle with a Ferrari V8 engine, built from scratch by one man, delivers unmatched sound, power, and presence

- Maxwell Hazan created a custom motorcycle using a Ferrari F355 V8 engine.
- The hand-built HF355 has roughly 400 hp and a 6-speed manual transmission.
- Despite its massive V8, the super bike weighs only 590 lbs with all fluids included.
Most sport bikes are built with high-revving engines that strike a finely crafted balance between raw power and sleek performance. Whether it’s a twin, triple, or inline-four, these machines typically cap out around 210 horsepower, unless they’re packing forced induction, like the famously over-the-top Kawasaki H2 – the one Tom Cruise rides in 2022’s “Top Gun: Maverick” blockbuster.

But for one custom motorcycle builder in the US, that kind of setup wasn’t quite enough. Maxwell Hazan had something far more ambitious in mind: a sport bike powered by the engine from a Ferrari F355.
Based in Los Angeles, Hazan has spent a considerable amount of time crafting this one-off creation, called the HF355. He recently completed the build and took it out for a spin on public roads, where it immediately stood out as one of the most extraordinary motorcycles we’ve ever seen.
Built From the Engine Out
It goes without saying that you can’t just take an existing sports bike and shoehorn a V8 into it. That meant Hazan had to build it from scratch, using Ferrari’s 3.5-liter engine as the base and constructing everything around it. The Italian naturally aspirated mill is mated to a six-speed transmission, as is typical on a bike like this, and uses a bespoke SC Project exhaust. With roughly 400 hp on tap, the HF355 is about as wild as a two-wheeler can get.
What’s particularly remarkable about the bike is that it only weighs about 590 lbs, or 267 kg with all its fluids included. That’s only around 132 pounds heavier than a typical 1,000 cc sport bike, which is impressive considering the size and complexity of the powerplant.
Familiar Form, Wild Function
The bespoke carbon fiber bodywork largely resembles a standard bike, retaining familiar proportions. The most obvious difference is that there are now two massive cylinder banks protruding from the sides instead of a streamlined inline-four.
There’s no word on what kind of acceleration figures the bike can lay down, but it should be rapid. With a power-to-weight ratio of 1,498 hp per tonne, which is about 500 hp per tonne more than a BMW S1000 RR, it’s fair to say the HF355 is on whole different level when it comes to performance.
