RILEY - CHASSIS NUMBERSas Old as the Industry, as modern as the Hour
I have taken the following Data from David Styles excellent book, 'As old as the Industry', and hope I haven't breached any copyright! If anyone knows any different to what is set out below, I would be grateful if they could correct me!
|1896-1907||100-??||Bikes, Tricars and Quads.
The Frame Number was stamped on the frame, and ran sequentially, without any model differentiation.
|1905-14||?||all V-Twin and 17/30hp cars.
Again, it appears that all models had sequential numbers, probably continuing with the series from above.
|Sidevalve (10.8, 11/40 & 11.9) Cars.|
C286- (3/4 digit)
|10.8 and 11/40 cars.
After 1922 a Letter suffix was added to the engine number showing the bodystyle the engine originally powered!:
|1925-28||69xxxx||All 11.9 Cars (69mm=cylinder bore).
The engine numbers are again thought to all have a model suffix, as above, with one addition:
|With the Launch of the 11.9 in 1925, and the 9 in late 1926, Riley Chassis Numbering started to get more organised, with at least a differentiation of which engine the car used. With the Riley 9 Chassis, there are also enough cars and records surviving to be able to provide an approximate yearly breakdown:
Riley 9's. July 1926 -- Aug. 1935
|July 1926 - Oct. 1930||600001-601000||MkI Chassis, RH Gearchange, Cone Clutch.

|1928-32||8001-8093?||Brooklands Speed Model.
There are suggestions that the last Brooklands Chassis Number was 8098, but evidence to date only goes as far as 8093.

From Summer 1935, Riley employed a new Chassis Numbering System, which not only identified the engine, but also the Year and Bodystyle originally fitted. This system continued into the postwar RM series, albeit with a few minor anomalies along the way!
The General style was thus:
SS 3 8 A X 1234
All Cars post July 1935
