McKenzie were motorcycles produced from 1921 to 1925, by George
1921 The McKenzie was produced as an ultra lightweight/featherweight,
in an attempt to provide a machine suitable for everyday transport. It
weighed a mere 80lb and had an open frame, unsprung forks, direct-belt
drive and a 170cc two-stroke Hobart
1923 As the model was a success and large numbers had been sold, the basic
model continued into that year. A new two-speed model was now added, with
1924 That new model was uprated in a new design and given a new 147cc Aza
two-stroke engine, Albion two-speed
chain-cum-belt drive, clutch and kick-starter. The open-frame miniature
also had a two-speed gear. The business faltered during that year.
1925 After restructuring the company, George McKenzie secured the
goodwill and continued production with the same two-model range, fitting
the lightweight with a larger Aza engine.
It was the last year of manufacture for the McKenzie.
