At the heart of the R12 lies a 745 cc two-cylinder boxer engine, which delivers a respectable 18 horsepower at 3,400 RPM.

The steel-pressed-loop frame provides a sturdy foundation, while the telescopic front fork enhances ride comfort and handling. Both the front and rear drums measure 200 mm in diameter, offering reliable stopping power, a critical aspect for safety and control. The motorcycle’s rigid rear suspension contributes to its vintage charm, providing a direct connection to the road. Notably, the R12 employs a kick starter, a nod to the simplicity and ruggedness of early motorcycle design. With a fuel capacity of 14 liters, riders can venture far with confidence, making it an ideal companion for both short journeys and extended adventures.
