Some 500 of these machines were built as sidecar machines and were mainly supplied to the army in 1935-36. The military XA had a driven side-car wheel and the drive could be disengaged for normal use. It was replaced by the AX2.

X40 1942
Police/Military escort machines ordered by the Vichy government as a replacement for head of state motorcycle squad's aging Rene Gillet 1000cc machines which could no longer keep pace with the fast cars in which Petain traveled, thereby posing serious risks for the riders. The X40 used cycle parts from the XA2, the 750cc engine of the AX2, and a number of X40 specific parts.

The machines were later used as escorts for General de Gaulle and Vincent Auriol, and after being retired from active duty in 1952 many were stored in Fontainebleau until the late 1960s.

Only 50 machines were built.


AX2

Produced 1938 to 1945

1st serial number: 160001

Colour: army green (with various shades depending on the regiments) or gendarmerie blue

This vehicle was strictly reserved for the military authorities. The motorcycle uses the stamped metal frame inspired by the other models of the range (fork with Neiman rings). The sidecar wheel was driven except on the first models.

The engine is a side-valve 800 cc flat twin fitted with a four-speed gear box. Power is transmitted to the rear wheel by drive shaft and conical torque, and the sidecar wheel is directly driven by the final drive unit. One engages the gear by the means of a pedal coupled with a hand lever, and the rotating throttle handle is coupled to a hand throttle for off-road use. The dog clutch is operated by a pedal.

A five-speed gearbox version with reverse gear was also available.

The trials machine (colours: cream or vivid red) differs from the other versions by its high muffler, narrow mudguards, the addition of a sump guard and the replacement of the centre stand by a stand on each wheel as well as a sidestand.
