The  electric-starting Triumph T140W TSS was launched in 1982 and featured an eight-valve cylinder head (derived from Weslake Engineering, hence the 'W' suffix) and a revised crankshaft designed to reduce vibration.
All T140W had an electric start, the new Italian-made 4-gallon petrol tank, twin front disc brakes and Marzocchi Strada rear shock absorbers as standard with Morris alloy wheels and an anti-vibration frame as options.

Whilst the UK/Rest of World kept the Amal Mk2 types as found on the standard 4 valve T140E, the US version had German- designed Bing carburettors that Amal made under licence in Spain.

For 1983/4, it was envisaged, in line with the UK/Rest of World range, that the TSS-AV  would also be fitted with the anti-vibration frame, rear-set footrests, a new seat-tail unit and TSX-style side panels all as standard.
