G2 models. Basically the same as model F4, made in 1934 (see previous chapter). Coil ignition fitted; Burman four-speed H.P.-type gearbox.

G2M models. The same as the G2 model, with the exception that a magneto was used in place of coil ignition.

Model G3. Hairpin valve-springs were introduced.

Model G80. This is basically the same as the 350-c.c. engine, but the O.H.V, rocker-gear is positively lubricated from the oil pump.

Model D5. This has an improved side-valve engine with detachable cylinder-head. A medium weight C.P.-type gearbox was fitted and is the same as 1934 models.

Model X4. Basically the same as previous models, but with changes in the connecting-rods and big-end assembly. Forked-type connecting-rods were first introduced for this season. Lubrication details for both gearbox and engine are as for 1939 models.

Dry-sump lubrication is used on all models similar to earlier engines. Side-valve engines have detachable cylinder-heads. A four-speed gearbox with positive foot-change is used on all these machines.
