Greeves motorcycles were produced by Invacar, a company which manufactured invalid carriages. Under the guidance of Bert Greeves, the move into motorcycle manufacture was decided in 1951, with the first machines available being announced in 1953, and the very first model line-up included a scrambles model, the 20S. This was the forerunner of the model offer here, the Hawkstone 20SA, which entered the range in 1958. This Hawkstone was purchased by the deceased owner at an indeterminate time, and has not been used for many years, being stored in recent times, Missing its rear wheel, it requires restoration, and is sold strictly as viewed. It should be noted that a set of Greeves forks accompany this machine, and are pictured separately. There are no documents with this lot.
