Technical Overview
1934 BMW R2 Series 3 Technical Analysis & Specification Breakdown
Built around BMW's allround motorcycle platform, the 1934 BMW R2 Series 3 utilizes a 198 cc (12.1 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 8 HP (5.9 kW) at 4,500 rpm, transferring power to the rear wheel through a 3-speed gearbox and shaft drive (cardan) final drive. With a specific output of 40.4 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the R2 Series 3 measures 130 kg (287 lbs) wet (curb), translating to a power-to-weight ratio of 0.06 HP/kg (16.25 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,303 mm (51.3 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 2.75 L/100 km provides an estimated theoretical range of roughly 400 km (249 miles) between fill-ups, while factory top speed is listed at 95 km/h (59 mph).
