Offered only in 1957, this model was an upscale version of a very popular model, the CS/57. The CSGT (Gran Turismo) was with the CS engine, but the head from the CSTL (Turismo Lusso) was used, including that’s engine’s helieal valve springs, a Dellorto MA 20B carburator and trunvcated double cone silencer. The electric system was modified aas well; The CSGT used a dynamo and a commutator ignition system. The single overhead camshaft engine generated 8 HP at 8,800 rpm, and power was fed through a 4-speed transmission, pushing the CSGT to a top speed of 100 km/h. The CSGT used a frame built from a combination of tubular and pressed steel parts. The front suspension was a telescopic hydraulic shock affair, while the rear suspension consisted of a swingarm with a pair of hydraulic shock absorbers.
