Overview

Introducing the 1965 Hercules A 175, a motorcycle that captures the spirit of the mid-60s with its bold sport styling and innovative engineering. Produced by the renowned German manufacturer Hercules, this model is designed for enthusiasts who crave a nimble ride that effortlessly balances performance and practicality. As a member of the sport category, the A 175 quickly carved out a niche for itself among riders seeking both spirited performance and everyday usability, making it a beloved classic in the vintage motorcycle community. At the heart of the Hercules A 175 lies a spirited single-cylinder, two-stroke engine with a displacement of 173 ccm. This compact powerhouse produces a respectable 9.30 HP at 5250 RPM, delivering a lively ride that makes navigating winding roads both fun and engaging. The engine's bore and stroke dimensions (62.0 x 58.0 mm) allow for a thrilling power delivery that keeps the adrenaline pumping. Paired with a Bing 24mm carburettor, the A 175 offers a responsive throttle that encourages spirited acceleration, while its chain final drive ensures a smooth transfer of power to the rear wheel. Weighing in at just 140 kg (308.6 lbs), this motorcycle boasts a commendable power-to-weight ratio of 0.0664 HP/kg, making it an agile performer on both city streets and open highways. The A 175 is equipped with features that enhance its sporty appeal and rider comfort. Its telescopic front suspension provides excellent handling and stability, ensuring that even the most twisting roads can be conquered with confidence. The rear swingarm suspension further contributes to a smooth ride, absorbing bumps and imperfections in the road. The drum brakes, both front and rear, offer reliable stopping power, though riders may find them less responsive than modern disc brakes. With a fuel capacity of 11.50 liters (3.04 gallons), the A 175 strikes a balance between range and weight, allowing for longer rides without sacrificing maneuverability. **
