Tiger Cub T20SR (Scrambler Road) &
T20SC (Scrambler Competition) 1962-65
Picture
"The Tiger Cub is a winner all the way" declared Belgium Trials and Scrambles Champion Roger Vanderbecken in one sales brochure.
​
​Two more versions on the 'Sports' Cub theme, the SR was the more road orientated machine with the SC being more off-road biased. They were real lightweight sports machines that averaged just 223 lbs (100 kg) on the scales.

​​Both models had all the performance parts fitted, 9:1 piston, 'R' cam, sport valve springs, crankcase undershield, heavyweight front forks, QD lights and speedometer, and the Lucas Energy Transfer Ignition to allow the machines to be used without a battery.
​
Adjustable rear suspension units were listed for the 1965 models.

​​The T20SR had the option of a close-ratio or extra close-ratio gear cluster and had road tyres and a low level exhaust system.



​
​Conversely the T20SC model came with either standard-ratio or wide-ratio gears, trials tyres and high level exhaust (option of silencer or extension pipe). It was also listed with lightweight alloy front and rear mudguards and was also to form the basis of the T20M Mountain Cub.

​Two-tone colour schemes being:
1962 : Burgundy and Silver Sheen
1963 : Flamboyant Flame and Silver Sheen
1964 : Kingfisher Blue or Hi Fi Scarlet and Silver Sheen
