The R60 was released at the same time as the R26, one year after the R50 and the R69. It thus completed the range with a touring model capable of being towed and replaced the R67/3. The entire range now had swinging suspension.
Apart from the displacement (different bore and stroke), the engine was identical to the R50. It only developed 2 hp more (28 hp) and the carburetors had the same diameter as the R50. Externally, the only way to distinguish a 500 from a 600 was by the shape of the cylinder, the fins of which were pointed at the front and rear.
It was replaced in 1960 by the R60/2.
The R60/2 replaced the R60 in the range in 1960. Like the R50/2 which replaced the R50, it only changed externally in a few details. The indicators at the end of the handlebars are now standard and the two-seater saddle is available as an option. On the engine side, the power increases and goes from 28 hp to 30 hp but 200 rpm higher, that is to say at 5800 rpm. Like the other models in the flat-twin range, the R60/2 is modified on the reliability of the engine. The crankshaft and the clutch are reinforced, the breather system is improved, the pistons are three-segment, the compression ratio goes from 6.5 to 7.5 to 1 and the carburetors adopt a needle instead of the needle-needle.
On the chassis side, the biggest modification comes in 1962 with the reinforcement of the frame. Gussets are added at the steering column and a reinforcement is added between the lower part of the frame and the tube supporting the axis of the swing arm.
In 1967, an evolution was proposed only for the American market, the R60US.
It was replaced in 1969 by the new series 5 and in particular the R60/5 after a production of 17,306 units.
