"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.
