Overview

Introducing the 1950 Ariel KH 500 Red Hunter, a quintessential representation of post-war British engineering and a beloved classic in the allround motorcycle category. With its striking red finish and robust yet elegant design, the KH 500 captures the spirit of adventure and freedom that motorcycling embodies. Born from the innovative lineage of Ariel, which was under BSA ownership since 1944, this motorcycle was crafted for riders seeking both performance and style, making it a favorite among enthusiasts and collectors alike. At the heart of the KH 500 is a robust 498cc twin-cylinder, four-stroke engine that churns out an impressive 28.03 horsepower at 6,500 RPM. This power is coupled with a 4-speed gearbox that allows riders to effortlessly navigate through various terrains, reaching a top speed of 145 km/h (90.1 mph). The engine's 7.5:1 compression ratio and air-cooling system contribute to its reliable performance, ensuring that riders experience a smooth and exhilarating ride. The motorcycle's power-to-weight ratio of 0.1584 HP/kg enhances its agility, making it an enjoyable companion on both city streets and winding country roads. The Ariel KH 500 Red Hunter comes equipped with several features that underscore its vintage charm while integrating practical performance capabilities. The duplex frame provides a sturdy foundation, while the telescopic front forks and rigid rear suspension offer a balance of comfort and control. The drum brakes at both the front and rear ensure reliable stopping power, essential for the spirited rides this bike invites. With a fuel capacity of 17 liters (4.49 gallons), the KH 500 is ready for long journeys, allowing riders to immerse themselves in the open road without frequent stops. **

Pros

  • Classic Aesthetic: The iconic red color and vintage design make the KH 500 a head-turner at any motorcycle gathering.
  • Robust Engine Performance: The powerful twin-cylinder engine provides excellent acceleration and a spirited riding experience.
  • Comfortable Handling: The combination of a lightweight frame and responsive suspension allows for easy maneuverability and enjoyable rides.

Cons

  • Limited Braking Power: While the drum brakes are reliable, they may not provide the stopping power found in modern disc brake systems.
  • Kick Start Only: The absence of an electric starter may be less convenient for some riders, especially in cold weather.
  • Rigid Rear Suspension: The lack of rear suspension travel could lead to a stiffer ride on bumpy roads compared to modern motorcycles with advanced suspension systems.
