Overview

Introducing the 1954 BSA Golden Flash, a true classic that embodies the spirit of mid-century British motorcycling. Positioned in the allround category, the Golden Flash is not just another motorcycle; it’s a symbol of the golden era of biking, where style met performance in a harmonious blend. With its sleek lines, polished chrome accents, and robust engineering, this motorcycle captures the hearts of enthusiasts and collectors alike. Whether you’re cruising through the countryside or navigating city streets, the Golden Flash is designed to deliver a ride that’s both exhilarating and comfortable, making it a versatile choice for riders of all preferences. At the heart of the Golden Flash lies a powerful 646cc twin-cylinder, four-stroke engine, which produces an impressive 35 horsepower at 4500 RPM. This engine not only delivers a lively performance but also provides a smooth and responsive ride, allowing you to feel every twist and turn of the road. The bore and stroke measurements of 70.0 mm by 84.0 mm create a balanced power delivery, complemented by a traditional carburettor fuel system that adds a nostalgic touch to the riding experience. The air-cooled design ensures reliability and simplicity, while the chain final drive contributes to the straightforward maintenance that classic motorcycle enthusiasts appreciate. With a power-to-weight ratio of 0.1842 HP/kg, the Golden Flash strikes a commendable balance between power and agility, making it a joy to ride on both long journeys and short commutes. The BSA Golden Flash shines not only in performance but also in its thoughtful features and design elements that reflect the era’s technological advancements. The single cradle frame provides a robust foundation, ensuring stability and confidence while navigating various terrains. The hydraulic telescopic forks at the front and twin shock absorbers at the rear deliver a smooth, controlled ride, absorbing bumps along the way. With drum brakes at both the front and rear, riders can enjoy reliable stopping power that aligns well with the bike’s vintage styling. The 19-liter fuel tank allows for extended rides without frequent refueling stops, and with a weight of 190 kg, the Golden Flash feels nimble and responsive, enhancing the rider's confidence and enjoyment. **

Pros

  • Classic Styling: Timeless design that appeals to vintage enthusiasts and collectors alike.
  • Smooth Ride: Hydraulic front forks and twin rear shocks provide excellent comfort and handling.
  • Simplicity of Maintenance: Air-cooled engine and chain final drive make it easy to service and maintain.
