A Brief History of the Marque
The 48cc Brisk was introduced in 1961 and was
sold (mainly in the domestic market) until 1965. It had but a single
speed and the 2-stroke engine put out 1.3hp at 4,250rpm giving the 40kg
bike a top speed of 40kph. The tubular frame was replaced by a pressed
steel design in 1962. In 1967 the Brisk 50/1 was introduced. Changes were mostly cosmetic with a rectangular tank, angular
front mudguard and a small square-bodied headlight. A single or dual
seat was available.
