Momo Prototipo Heritage Steering Wheel – 350 mm | Black Leather / White Stitch / Black Spokes | Italian Performance Steering Wheel

The Momo Prototipo Heritage is one of the most iconic steering wheel designs in motorsport history — a direct evolution of the original Momo Prototipo that equipped Ferrari, Lancia, and Alfa Romeo factory race cars throughout the 1970s and 1980s, now reinterpreted in the Heritage series with the same fundamental design language and Italian craftsmanship that made the original a legend. This 350 mm diameter version is finished in black leather with white contrast stitching and black spokes — a classic, purposeful combination that reads as both period-correct and timeless in any performance interior. Momo steering wheels require a vehicle-specific Momo hub adapter for installation — sold separately.

Key Features:

• Prototipo Heritage design — Momo's reinterpretation of the original Prototipo — the steering wheel that equipped Ferrari, Lancia, and Alfa Romeo factory race cars in the 1970s and 1980s — the same fundamental design language in a modern Heritage series execution
• 350 mm diameter — a classic performance steering wheel diameter — smaller than the factory steering wheel on most modern vehicles for a more direct, more connected steering feel with less arm movement required for full lock
• Black leather rim — genuine leather rim covering in black — a premium, tactile grip surface that improves with use and develops a natural patina over time
• White contrast stitching — white stitch detail on the leather rim — a classic motorsport aesthetic that references the period-correct Prototipo's design language
• Black spokes — black-finished spokes for a clean, purposeful appearance that complements the black leather rim without the visual noise of polished or chrome alternatives
• Momo hub required — requires a vehicle-specific Momo hub adapter for installation — sold separately — verify the correct hub adapter for your specific vehicle before ordering
• Italian craftsmanship — manufactured by Momo, the Italian steering wheel and wheel brand with over 60 years of motorsport heritage

The Prototipo Heritage — A Design with Motorsport DNA:

The original Momo Prototipo was designed in the early 1970s and became the steering wheel of choice for some of the most celebrated factory race cars of the era — Ferrari 312, Lancia Stratos, Alfa Romeo GTV, and many others. Its distinctive three-spoke design, leather-wrapped rim, and compact diameter were optimized for the demands of motorsport driving — quick, precise inputs, maximum feedback, and a grip that allowed the driver to feel the car's behaviour through the wheel. The Prototipo Heritage reinterprets this design for the modern performance enthusiast — maintaining the original's proportions, spoke geometry, and design language while incorporating contemporary materials and construction quality. For performance car owners who want a steering wheel with genuine motorsport heritage rather than a generic aftermarket alternative, the Prototipo Heritage is the correct choice.

Why a 350 mm Steering Wheel?

• More Direct Steering Feel: A smaller diameter steering wheel requires less arm movement to achieve the same steering input — reducing the arc of movement required for full lock and allowing faster, more precise steering inputs. For performance driving where quick, accurate steering corrections are important, a smaller diameter wheel is a meaningful improvement over the larger factory wheel.
• Driver Positioning: A smaller steering wheel allows the driver to sit closer to the wheel while maintaining correct arm position — improving the driver's ability to brace against the wheel under lateral G-forces and providing a more connected, more controlled driving position.
• Aesthetic: A 350 mm steering wheel fills the cockpit with a period-correct, motorsport-inspired presence that a larger factory wheel cannot replicate — the visual impact of a quality aftermarket steering wheel is immediate and transforms the interior's character.
• Note on Airbags: Aftermarket steering wheels do not include airbags. Installing an aftermarket steering wheel removes the factory airbag from the steering column. This is a safety consideration that must be understood before installation. Many performance and track-day drivers accept this trade-off; street-driven vehicles should consider the implications carefully.

Disconnect the vehicle's battery and wait at least 15 minutes before working on the airbag system to allow the airbag capacitor to discharge. Follow the vehicle manufacturer's airbag disarming procedure before removal.
• Torque the steering wheel centre nut to the hub adapter manufacturer's specified torque — an incorrectly torqued steering wheel can come loose during driving
• Verify correct steering wheel installation by checking for free rotation without binding and correct centring before driving
• Professional installation recommended if unfamiliar with airbag system disarming procedures
