1957 - 1964 Velocette VALIANT[edit | edit source]

Nice looking motorcycle, this Valiant, powered by a little OHV boxer engine with a cowling (Velocette preferred to call it a “bonnet”) over the top in an effort to give it somewhat sporty looks. It had a full cradle frame with a telescopic fork up front, a swingarm with shock absorbers at the rear, 4-speed gearbox and a curb weight of 270 pounds with 3.5 gallons in the tank—not bad. Engine output was said to be 12 horsepower at 7,000 rpm, with a top speed of around 70 mph. For a 200 (192cc in actuality), that was decent performance.
