Triumph Speed Twin 1951 - Specifications & Review

Introducing the 1951 Triumph Speed Twin, a timeless classic that embodies the spirit of post-war motorcycling. Positioned in the allround category, the Speed Twin was designed to cater to a variety of riders—from weekend warriors to daily commuters—offering a delightful blend of performance, style, and versatility. The Speed Twin not only solidified Triumph’s reputation for producing reliable motorcycles but also helped define the landscape of British motorcycling in the early 1950s. Its elegant lines, coupled with a robust engineering pedigree, make it a sought-after machine for enthusiasts and collectors alike.

At the heart of the Speed Twin lies its spirited 498cc twin-cylinder, four-stroke engine, which produces a respectable 27 horsepower at 6,300 RPM.

The combination of a lightweight frame, weighing in at just 158.8 kg (350 pounds), and a power-to-weight ratio of 0.1701 HP/kg translates to nimble handling and agility, making it an enjoyable ride for navigating city streets or carving through winding country roads.

The 1951 model features several key technological advancements for its time, including a Lucas alternator for reliable ignition and an Amal carburettor that optimizes fuel delivery for efficient performance. The telescopic front suspension enhances comfort and control, while the rear suspension can be fitted with an optional sprung hub for added ride quality. Both front and rear drum brakes provide adequate stopping power, allowing riders to feel confident while managing their speed. The Speed Twin’s design pays homage to classic aesthetics, with chrome accents and a minimalist approach that appeals to purists and modern riders alike.
