The first of what would become the RG series of 500cc overhead-valve sports models was introduced in 1932 as the RSS, which was based on the sidevalve RL of 1931. First seen in October 1930, the RL eschewed the trend towards unitary construction of the engine/gearbox followed by other French manufacturers such as Peugeot, keeping the 'box separate but enclosing it within the crankcase casting (think 1958 AJS/Matchless Model 14/G2, only better). In 1937 the RSS was replaced by the SRES, with enclosed valve gear and single-port 'head, which was followed towards the war's end by the RCMA, a model ordered by the State authorities. When the civilian RGSE emerged in 1946, it looked pretty much like its immediate forebear apart from the incorporation of the pushrod tubes within the cylinder barrel casting. One of Terrot's last large four-stroke models, the successor RGST 'Grand Sport' was introduced in late 1948 featuring the combination of a telescopic front fork and plunger rear suspension that characterised machines of the immediately post-WW2 period. Weighing 190kg (418lb), the RGST had a top speed of around 125km/h (78mph). A version with swinging-arm rear suspension – the RGSO – was introduced in 1955. Production ceased in 1957.

An older restoration, this Terrot RGST is fitted with special Merat rider's and Dunlop 'Drilistic' pillion saddles. The machine is offered with French Carte Grise normale.

    La première machine de ce qui allait former la série RG des types sport à culbuteurs de 500 cm3 fut introduite en 1932 sous la forme de la RSS issue de la RL « latérale » de 1931. Dévoilée en octobre 1931, la RL ne respecta pas la mode de l'adoption de la boîte en bloc avec le moteur suivie par d'autres constructeurs français comme Peugeot, en conservant la boîte séparée tout en l'intégrant au carter (pensez à la meilleure AJS/Matchless Model 14/G2 de 1958). En 1937, la RSS fit place à la SRES avec distribution enfermée et culasse à simple échappement suivie à la fin de la guerre par la RCMA, type commandé par les autorités gouvernementales. Lorsque la RGSE civile apparut en 1946, elle ressemblait beaucoup à sa devancière à l'exception de l'incorporation des tubes enfermant les tiges de culbuteurs dans le cylindre. Un des dernières grosses motos à quatre temps de Terrot, la RGST « Grand Sport » qui lui succéda en 1948 se distinguait par la combinaison d'une fourche avant télescopique et d'une suspension arrière à plongeurs, solutions caractéristiques des machines de l'immédiat après-guerre. Pesant 190 kg, la RGST atteignait 125 km/h environ. Une variante à suspension arrière oscillante, la RGSO, apparut en 1955. La production cessa en 1957.

    Ancienne restauration, cette Terrot RGST est équipée d'une selle pilote Merat et d'un tan-sad Dunlop « Drilistic ». Sa carte grise française est normale.
