World-renowned custom motorcycle designer Maxwell Hazan has launched his HF355 after a year-long, extraordinary project. The HF355, featuring a 3.5-liter V8 engine derived from the Ferrari F355, is a unique machine, boasting both performance and design. With 400 horsepower, this custom motorcycle boasts a power-to-weight ratio that surpasses even track motorcycles.
A Ferrari-powered motorcycle is here
The project is based on the legendary, naturally aspirated V8 engine from the Ferrari F355, produced between 1994 and 1999, capable of revving 10,000 rpm. The engine is mated to a six-speed manual transmission. Weighing 107 kilograms, the engine alone accounts for nearly half of the bike’s dry weight. The HF355’s total dry weight is 250 kg and its wet weight is 267 kg.

Despite these weights, the HF355’s performance is remarkable compared to high-end supersport models. For example, the BMW S1000 RR’s power-to-weight ratio is 0.46 hp/lb, while the HF355’s is 0.67 hp/lb. This difference demonstrates that the HF355 is not only powerful but also quite fast.
All of the bike’s components were designed from scratch by Hazan. Instead of a standard chassis, the entire structure is built directly around the engine and transmission. The body panels are made of carbon fiber, while the exhaust system is entirely handcrafted. The suspension systems are also custom-developed. The acrylic glass and aerodynamic fins at the front end reinforce the racebike character both functionally and in design.
A special radiator system and four computer-controlled electric fans are used for engine cooling. The dry-sump oiling system, positioning the oil tank above the engine, saves space and improves serviceability.
While the HF355’s body length is similar to that of an adventure motorcycle, its sportbike profile is preserved thanks to the short 1,600 mm wheelbase. Ergonomics-wise, seat height, handlebar distance, and footpeg positions were repeatedly reviewed to optimize riding comfort and control.
The HF355, the result of all this engineering and design effort, is not intended for mass production. Only one motorcycle was produced, and final technical specifications and performance figures have not yet been released.
