Vintage 1926 AJS GR10 racing motorcycle start up and walk around in the Kop Hill Paddocks.

A rare 1926 AJS GR10 race-bike at the 2023 Kop Hill Climb.
This machine has had a rich history, and is believed to have TT provenance, indicated by TT and Manx stamps etched into parts of the machine. It also features a left-hand-side oil filler, synonymous with early pit stop requirements of the Island race.
This bike is believed to have been dismantled on retirement from the TT, and the frame and components shipped off to Australia. These were repatriated to England in the ‘50s and fitted with a period 1928 K8 500cc overhead valve engine. The bike was then raced in the 1950s and ‘60s and has remained in the same family for a number of decades. There is no denying that this is one hell of a machine.

This is not a GR 10! There was never a GR 10 from AJS. The 500 racing model from 1926 was called G 10.
This motorcycle is still very interesting. Because the frame, petrol and oil tanks are racing. The oil tank is even a TT factory model. The aluminum clutch is also racing.
But all other components such as the engine (Model K 8), gearbox, rear wheel... are ordinary components.
