Key specifications
Overview
Introducing the 1928 BMW R63, a motorcycle that perfectly encapsulates the spirit of the late 1920s while showcasing BMW's commitment to quality craftsmanship and innovative engineering. Positioned as an allrounder in the burgeoning motorcycle market, the R63 was designed not only for leisurely rides but also for the burgeoning touring enthusiast. With its striking design and robust construction, it quickly became a favorite among riders who sought both style and performance. At the heart of the R63 is a meticulously engineered two-cylinder boxer engine, a hallmark of BMW design that offers both distinctive aesthetics and impressive performance. With a displacement of 735cc, the engine produces a robust 24.07 horsepower at 4,000 RPM, allowing riders to reach a top speed of 120 km/h (74.6 mph). This four-stroke powerhouse is complemented by a smooth shaft drive, providing seamless power delivery and a ride that resonates with the sounds of the open road. The air-cooled engine, with a compression ratio of 6.2:1 and a 24mm carburettor, delivers a satisfying blend of torque and throttle response, making the R63 a joy to ride—whether navigating winding country lanes or cruising along city streets. What sets the R63 apart are its thoughtful features and technology that prioritize rider comfort and control. The steel double cradle frame provides a sturdy foundation, while the leading link front suspension enhances stability and handling, especially on uneven surfaces. The single drum brake in the front ensures riders can stop effectively, an essential feature for safety during any adventure. Weighing in at 152 kg (335 lbs) and with a fuel capacity of 12.5 liters, the R63 maintains a manageable weight that makes it an accessible option for both experienced riders and newcomers alike. Additionally, the classic kick starter adds a nostalgic touch, reminding riders of a time when connecting with their machine was a tactile experience. **
