Tiger Cub T20SH (Sports Home) 1962-66
As the name suggests, the T20SH (Sports Home) model was intended mainly for the UK market. It was a development of the T20SS and SL models, which made it a real lightweight sports machine for the road. A 9:1 piston, 'R' cam, sports type valve springs, a close ratio gear cluster and large bore Monobloc carburettor made sure of that. This was a real 'Baby Bonneville'.
A 'D' shaped speedometer was standard but a tachometer was an option, and if fitted, a matching round speedo complimented it. The drive to the tachometer on early models was from the end of the camshaft, but by 1963 the drive had moved to where the old top mounted points assembly used to fit. A two-tone, three gallon 'humped' tank was fitted with the one-piece 'mouth organ' badges and all T20SH machines had the crankshafts running in the two ball race bearing engines, no plain bush. The engines being updated through the years as soon as improvements came into being.

After 1964, the frame received double gusseting under the headstock and from 1965 the right-hand side tube on the rear subframe was cranked out top and bottom, rather than just at the bottom as previous years. Flat or upswept handlebars could be specified and all machines had both a side and centre stand fitted along with a QD headlamp. A low level exhaust was the standard 'from the factory' fitment.
