Introduced in 1958 with the standard Model 14/G2, production continued
in various forms until 1966.
In 1958 a standard G2 was ridden from London up to Silverstone, where a
group of journalists made an attempt to ride this 250cc for 250 miles in
250 minutes. Mainly in torrential rain, they unfortunately managed only
59.1 mph average and then rode the bike back to London - still a good
effort for 1958. (Click here for a photo of the event)
A factory modified 14CSR was raced in the Thruxton 500 mile race in 1964
and, with Peter Williams and Tony Woods riding, they won the 250 class
averaging 61.6 mph.
These machines have nice clean lines and appear to be unit construction,
which they are not. They became known as the 'lightweights', although
once again this is far from the truth, weighing in at between 322 lbs.
and 328 lbs.
Over their production life they changed very little and are easily
Introduced in 1960, the 350cc lightweight models had a short production
run until 1962. By and large they are as they look, a slightly bigger
version of the 250cc models. Only one standard model was made in each marque.
