Despite the depredations of the war Giovanni was able to develop his designs so quickly that in 1948 he was able to produce a range of road machines. There was a 98cc model 125cc and 250cc models and an experimental 250cc racing twin. The designer of these machines was an ex-Gilera factory engineer named Salmaggi who had worked on the famous Gilera Saturno.
Despite the odds a rare and pristine example of Parilla's most successiul racing model has been maintained by Cecil White. Previously owned by talented artist Alan Puckett the Parilla was imported from the United States after being restored by Earl Workman. This example was originally a work's racing model which produced 34 bhp at 10 000 rpm and had a top speed of 185 kmh. Cecil quotes Alan Puckett as saying that the work's motor is very sharp.
The Parilla racing motor is clean, highly polished and uncluttered. The gearbox is in - unit and the design is modern looking and in excellent condition. There are no rough edges anywhere in sight and the fine engineering expected of the Italian craftsman is clearly evident. In the interests of preserving the genuine Work's motor a Grand Sports Wildcat Scrambler motor has been fitted. Alan Puckett had the Grand Sports motor as a spare and could not resist fitting a brand new motor to a Classic Racer.
This engine makes 27 bhp at 9500 rpm and runs on a 9.5 : 1 compression ratio. The bore and stroke of 68 x 68mm is fed by a 28mm Dell'orto carburettor with a remote rubber mounted float and the motor is capable of propelling the bike at 175 kmh. Looking at the bike one is struck by the overall small dimensions, the narrow scalloped tank and the clean uncluttered lines of the motor. The engine features a large alloy finned head and a high mounted camshaft which is chain driven from the crank. The rockers are actuated by short (50mm) pushrods and are set parallel to the crankshaf. The pushrods are thoughtfully enclosed in rubber boots and the overhead valves are controlled by hair-pin valve springs. This short mechanism allows for high revs and also allows the head to be removed without disturbing ignition timing.
