1966 TRIUMPH MOUNTAIN CUB BACKGROUND
The 200cc T20 Tiger Cub was produced from 1956 through 1968 and sold quite well for Triumph. The original Cub was introduced in 1953 at the Earls Court Motorcycle Show in London England as a 150cc commuter, at a time when there was a very big market for commuters. However, the Cub was designed specifically, and cleverly, to fill a very specific part of that growing market. England was about to pass the “Learner Law” requiring all motorcycle riders under the age of 18 could not ride anything larger than a 250. This created a boom in the bottom of the market. Parent-company BSA had their own 125 Bantam 2-stroke, and the C25 250 4-stroke single. So, Triumph launched the Tiger Cub as a 150, sort of splitting the difference.

1966 TRIUMPH MOUNTAIN CUB STYLING
They also made it smaller, sort of a scaled-down Bonneville. And that wasn’t by accident. Legendary Triumph designer and stylist Edward Turner personally designed and styled the Tiger Cub, and it shows. This was a big part of the appeal that helped to make the Tiger Cub such a hit, certainly in the UK home market. Not so much in the US, who had no such learner law. But they still made it across the pond, and sold reasonably well in the US, where there were street versions that looked like miniature Bonnevilles, commuters that resembled Triumph’s ‘Bathtub Bikes’, and semi-off road versions that looked like a TR6. The good looks helped a lot, but their reduced size either helped or hindered sales. Being smaller, with one of the lowest seat heights on the market, they appealed to the younger riders the Triumph Tiger Cub was designed for. But, they held less appeal for full-sized, and/or more experienced riders. There’s no disputing that the Tiger Cub is a great-looking machine.
