Rumi Junior Gentleman

The Gentleman was included in the Rumi catalogue in 1959 and was intended to replace the famous Junior model (at least in some markets), from which it inherited the lightweight frame and swingarm rear suspension.

Previously most components had been designed and produced in-house, but for this model Rumi chose to use components produced by specialists for the telescopic front forks (Marzocchi), rear shock absorbers and brakes.

Presented to the motorcycle press in March 1960, the Gentleman was designed for competition in the Sport category and was offered initially also with a 175 cc engine; this capacity was achieved by increasing both the bore and the stroke of the 125 cc engine, resulting in a considerable boost in power, to 6 HP. The Gentleman was originally fitted with a fuel tank which allowed for mounting of the external magneto, already supplied on some sports models. However, as there was no percieved interest in that arrangement, it reverted to a more conventional tank on later models.

The machine was delivered with aluminum alloy cylinders supplied by the German K.S. firm; however, some examples were fitted with cast iron barrels towards the end of production.

Intended for formula 2 racing it was fitted with two 22 mm carburettors. It made its competition debut in the Sassi-Superga of 1960 in the 125 and 175 cc classes.

Gentleman production continued until the factory closed.
