[6] A later development in 1963 was to site the points at a more conventional location on the end of the camshaft, accessed via a chrome cover below the base of the cylinder.

[2] The Sports Cub designated T20SH featured slimline mudguards, no rear panelling or headlamp nacelle and with a higher compression ratio and other engine modifications were timed at 74 mph mean maximum by Motor Cycle magazine.

[7][2] The last model made was the T20 Super Cub, which, for economy of production cost,[8] used a basic frame and other parts common to the BSA Bantam D10 including larger diameter wheels with full-width hubs.

The top frame tube of the Tiger Cub was lower than normal, leaving the headstock poorly supported.

[11] In 1961, the driving licence law for Triumph's home market in Great Britain was changed, restricting learner motorcyclists to a maximum of 250cc.
