BMW Cafe Racer Seats

BMW Café Racer Seats and Subframe Kits

Vonzeti specialises in handcrafted BMW Café Racer seats, subframes and custom motorcycle parts for classic BMW Airhead Boxer Twin motorcycles. Designed for riders, builders and enthusiasts, our BMW café racer seat kits help transform iconic BMW models into clean, balanced and beautifully finished custom machines.

The BMW boxer-twin layout has been part of BMW Motorrad history since the BMW R 32 of 1923, and it continues to influence modern BMW motorcycles today. For custom café racer, bobber and scrambler builds, however, the most popular donor bikes are often the classic two-valve, air-cooled BMW “Airhead” models produced from the late 1960s through to the mid-1990s.

These classic BMW Airhead motorcycles are known for their distinctive flat-twin engines, simple mechanical layout, shaft drive, strong engineering and timeless profile. They remain one of the most popular platforms for custom BMW café racer conversions.
