Overview
Introducing the 1936 BMW R3: A Timeless Classic The 1936 BMW R3 is a stunning example of early 20th-century engineering that perfectly encapsulates the spirit of adventure and innovation that defined the era. Positioned as an allround motorcycle, the R3 was designed to cater to a wide range of riders, from commuters to weekend explorers. With its classic lines and unmistakable BMW badge, this motorcycle not only offers a glimpse into the past but also serves as a reminder of the brand’s commitment to quality and performance. The R3's elegant design and robust build make it a cherished piece for collectors and classic motorcycle enthusiasts alike. At the heart of the R3 lies a spirited 305cc single-cylinder, four-stroke engine that produces a respectable 11.01 horsepower at 4,200 RPM. This engine configuration not only delivers a charmingly vintage riding experience but also allows the motorcycle to reach a top speed of 100 km/h (62.1 mph). The 6.1:1 compression ratio, combined with an 18mm carburettor, ensures smooth power delivery while maintaining impressive fuel efficiency, consuming just 3.00 litres per 100 km. The air-cooled engine coupled with a dry single-plate cable-operated clutch and a reliable shaft drive ensures that riders enjoy a smooth and responsive ride, whether navigating city streets or tackling winding country roads. The R3's chassis is constructed with a single cradle frame, offering a blend of rigidity and comfort that enhances handling. The motorcycle is equipped with drum brakes, both front and rear, providing confident stopping power with a diameter of 180 mm (7.1 inches). While the front suspension features a cartridge design for improved handling, the rear suspension remains rigid, which adds to the bike's classic character. With dimensions of 1,980 mm in length, 850 mm in width, and a height of 950 mm, the R3 strikes a balance between compactness and comfort, making it accessible for a variety of riders. Additionally, the kickstarter mechanism is an authentic touch, reminding riders of simpler times when the thrill of starting a motorcycle was part of the experience. **
