BMW R 63

The BMW R 63, introduced in 1928, represents a significant chapter in the early history of BMW Motorrad, cementing its reputation for robust and well-engineered machines. As the company's first sport-oriented motorcycle, it emerged from a lineage that prioritized shaft drive and horizontally opposed twin-cylinder engines. This model was a direct competitor to other high-performance motorcycles of its era, such as the Brough Superior SS100 and the Indian Four, aiming to capture the market for riders seeking a powerful and reliable touring or racing platform.

At the heart of the R 63 was a 735.0 ccm (44.85 cubic inches) two-cylinder boxer, four-stroke engine. This powerplant generated a respectable 24.1 HP (17.6 kW) at 4000 RPM, a considerable output for the late 1920s. This power propelled the R 63 to a top speed of 120.0 km/h (74.6 mph), making it one of the faster motorcycles available at the time. Fuel capacity stood at 12.50 litres (3.30 US gallons), offering a decent range for extended journeys. The engine's design, with its cylinders protruding into the air stream, was characteristic of BMW's engineering approach, facilitating effective cooling.

Riding the R 63 would have provided a distinct experience, characterized by a stable ride and the characteristic thrum of the boxer engine. While modern comfort features were absent, the R 63 offered a relatively upright stance for the rider, suitable for longer distances. Its shaft drive system contributed to a smooth power delivery, a notable advantage over chain-driven motorcycles of the period, reducing maintenance and increasing reliability. The suspension, while rudimentary by today's standards, was designed to handle the varied road conditions of the late 1920s, offering a predictable ride.

The BMW R 63 was primarily aimed at the discerning rider who valued performance, reliability, and engineering quality. This included enthusiasts interested in long-distance touring, competitive events, or simply owning a top-tier motorcycle. Its robust construction and straightforward mechanics appealed to those who appreciated a well-built machine capable of sustained high speeds. Today, the R 63 is a highly sought-after collector's item, representing a pivotal moment in BMW's history and a testament to early motorcycle engineering prowess.
