Lambretta (Innocenti) SX 150 (X 150 Special)

Lambretta (Innocenti) SX 150 (X 150 Special)


Lambretta SX 150
Series 3

The Lambretta Special X is derived from the Special and TV models. The TV (GT) 200 was superseded by the SX 200, while the SX 150 replaced the 150 Special. The exciting and timeless shape of the bodywork was mainly retained. The main difference between the SX 150 and the Special was the colour scheme. The silver paint is replaced by off-white or apple green (which apparently was not in great demand). In addition the SX 150 features a chromed mudguard crest and a polished horn grille. Both SX 150 and 200 have a large “X” plus the respective capacity stated over the Special badge on the legshields. The rear frame badge not reads “Innocenti” on both models.

Engine-wise the 150 gets its deserved makeover and now uses the SH20 carburettor as well. Combined with a new cylinder, peak performance is increased t 9,38 hp, giving a top speed of 96 kph. Also the SX 150 is the only Lambretta that uses two cylinder head gaskets at least if you don't count the twin cylinder prototypes.

Towards the end of the production the side-panel handles were replaced by steel clips under the panels, the same system to be used by the later DL. Also, the steel toolbox was replaced by a plastic item and the rectangular Innocenti badge superseded the previous shield. The last models of the SX 200 had the wheel-rims and brake-drums painted silver.

After three years and 31.238 scooters built, production of the SX 150 ceased in January 1969.
