Founded in 1964, MOMO Italy, is a company renown for its unique designs, superior quality, maximum safety standards and technological innovation in the automotive industry worldwide.
It all started with the passion of racing and gentleman race car driver Gianpiero Moretti, whose understanding and true passion for motorsports led to the creation of products that understood drivers' real needs. The same principles and believes still live in MOMO today, making sure we always deliver optimum and innovative automotive products for competitive drivers and auto enthusiasts like you.
MOMO has brilliantly carried on the business of developing innovative racing products, incorporating ambitious technological goals and continuing to improve the quality, safety and the superior design of MOMO products. An example of the goals achieved by the Company was the exclusive supply of MOMO steering wheels for the GP2 Championships in Europe and Asia. More recently in the US, MOMO has developed a new generation of steering wheels for NASCAR, which are currently used by many top teams and drivers.
MOMO and Porsche have collaborated on various projects, from high-performance steering wheels to custom builds and motorsport partnerships. MOMO’s iconic Prototipo steering wheel is a favourite among Porsche 911 owners, while their collaboration with Emory Motorsports led to the unique 1960 Porsche MOMO 356 RSR Outlaw. MOMO has also been involved in Porsche racing, notably with the MOMO-Megatron team in the Porsche Mobil 1 Supercup. These collaborations highlight both brands’ commitment to innovation, design, and motorsport excellence.
