Kestrel was a motorcycle produced in 1903. Few details are available.
It was a typical primitive with either a Minerva or a MMC engine fitted into a heavy-duty bicycle frame. Normally the engine hung from the downtube and it had direct-belt drive. It was probably built by a cycle dealer.
1909 'Mrs Thomlinson, on her Kestrel motor cycle, secured third place, her average speed being 17.882 miles per hour.' at the Hull and East Riding Auto-Cycle Club meeting.
