Key specifications
Overview
Introducing the 1965 BMW R27, a classic motorcycle that epitomizes the blend of performance, reliability, and timeless design that the BMW brand is renowned for. Positioned as an allround motorcycle, the R27 was designed to cater to both seasoned riders and those new to the two-wheeled world. With its understated elegance and robust engineering, it stands as a testament to the enduring appeal of mid-20th-century motorcycles, promising a delightful ride whether you're navigating city streets or cruising country roads. At the heart of the R27 is a spirited 247cc single-cylinder four-stroke engine that produces a commendable 17.95 horsepower at 7400 RPM, allowing the bike to reach a top speed of 130 km/h (80.8 mph). With an 8.2:1 compression ratio and a dual-purpose bore and stroke of 68mm, the engine delivers smooth power across the rev range. Riders will appreciate the efficient air cooling system and the carburetted fuel system, which together ensure a fuel consumption of just 3.30 liters per 100 km (approximately 71.28 mpg). The 4-speed gearbox paired with a shaft drive provides a seamless power delivery, making the R27 not just an efficient commuter but also an enjoyable weekend ride. The 1965 R27 boasts a host of features that showcase BMW’s commitment to quality and innovation. The steel twin-looped frame offers both strength and agility, while the cartridge front suspension and twin-shock swingarm rear suspension ensure a comfortable ride regardless of road conditions. With 160mm drum brakes at both the front and rear, riders can count on reliable stopping power. Weighing in at 162 kg (357.1 pounds) with fluids, the R27 strikes a balance between stability and maneuverability. The classic kick starter adds to the vintage charm, inviting riders to engage with the motorcycle in a way that modern electric starters often bypass. **
