Engine & Frame Numbers

Engine numbers are usually located on the drive side of most British motorcycles below the cylinder barrel or above the primary cover on the engine case its self.

What this chart is intended to be: This chart has been developed as an additional reference guide more so then simply dating off Sturmey-Archer hubs for the positive identification of Raleigh frames and entire bicycles. As proper factory documentation is very limited, the following charts are a constant work in progress; they have been compiled by examining numerous Raleigh frames from each period, component date codes, decal schemes, color availabilities per year; and – occasionally – official papers.

That said, these charts are representative of U. There isn’t enough data to claim either option as absolute. Keep in mind that these charts are incomplete, and there is a reasonably wide margin of error between serial cutoff dates. Nevertheless, please put your mind at ease – these serial charts have been checked, re-checked, and are as accurate as I can provide at their time of publication. If new information is found, these charts will be duly updated to reflect such. Otherwise, you might accidentally misidentify your Raleigh bicycle.

If your Raleigh is equipped with a Sturmey-Archer rear hub that you suspect has not been been changed, check the date code on the hub’s shell as well for additional verification. I have put considerable effort into keeping these charts accurate, and – as stated before – not all of them are finalized. Therefore, I would prefer that the charts remain completely accessible for editing when necessary.

However, feel free to link to this page if you wish to make reference to the chart.
