Corona Junior were motorcycles produced by them from 1919 to 1922
1919 The Corona Junior was first announced - with a 448cc sv four-stroke
single engine. The plan was to produce the machine in large quantities
from early in the year. The design was quite striking and amongst many
of the special features was a patented auto-lubrication system and knock-out
wheel spindles, and a very eye-catching black and white striped tank. Several
transmission options were also available.
1920 The design was revised and the automatic lubrication system was replaced
by mechanical-pump oiling. The two-speed gear option was withdrawn.
1922 Only a three-speed model with a Sturmey-Archer
gearbox survived for that year, and then the marque disappeared.
