Overview

Introducing the 1970 BSA A 65 SS Firebird, a remarkable piece of British engineering that epitomizes the classic motorcycle spirit of the late 60s and early 70s. Positioned as a stylish and powerful tourer in the classic motorcycle market, the A 65 SS Firebird blends performance with iconic aesthetics, making it an appealing choice for enthusiasts and collectors alike. With its striking lines, chrome accents, and a distinctive tank design, this motorcycle captures the essence of the era while delivering a ride that is both exhilarating and comfortable. At the heart of the BSA A 65 SS Firebird lies a robust 654cc twin-cylinder, four-stroke engine, which produces a commendable 49 horsepower at 7,000 RPM. This impressive powertrain not only pushes the bike to a top speed of 175 km/h (108.7 mph) but also provides a thrilling experience that resonates with riders who crave performance. The 9.0:1 compression ratio and well-balanced bore and stroke measurements (75.0 x 74.0 mm) ensure smooth acceleration and spirited handling. Paired with a reliable 4-speed gearbox and chain final drive, the Firebird offers a responsive and engaging ride, whether you're cruising along country roads or tackling city streets. In terms of features, the A 65 SS Firebird is equipped with expanding brakes both at the front and rear, providing adequate stopping power for its weight of 218 kg (480.6 lbs). With a fuel capacity of 18 liters (4.76 gallons), riders can enjoy long journeys without frequent stops at the pump, making it a practical option for enthusiasts looking to cover distance. The air-cooled engine design adds to its classic charm while requiring less maintenance compared to liquid-cooled counterparts. The overall riding experience is enhanced by the bike's ergonomics, allowing for a comfortable posture during extended rides. **
