Herner was a motorcycle produced in 1923 by Herner Engineering of Coventry.
This small firm produced an all-weather machine, as was the fashion in the mid-1920s. They used a 147cc two-stroke Villiers engine with extensive weather shielding, including a windshield. The frame was constructed of straight tubes and fitted with a two-speed Albion gearbox. The handlebars projected rearwards from a long column, attached to the steering head and passing through the windshield.
The engine would have struggled to cope, and progress would have been very slow indeed.
