A Brief History of the Marque
A.J. Robertson of Queen Street, Edinburgh built and rode these JAP-engined singles. Production
began in 1925 and ceased the following year.
This brand was one of the few Scottish makes and was built from
1925 to 1926.
1925 AJR came from the initials of A. J. Robertson, of Queen Street,
Edinburgh, who, at the age of nineteen, launched the name when he rode
in the TT. His machines all had a JAP
engines and Sturmey-Archer
gearboxes, but his motorcycles retired from the TT that year in the Lightweight,
Junior and Senior events.
1926 There was a four-model range available - all with JAP
engines of either 350cc or 500cc, Sturmey-Archer
three-speed gearbox and Druid forks;
further options were available as Sports and Racing models,
and single or twin-port variations. The machines were all very expensive.
Entries in the TT were disappointing, bringing retirement in the Senior
and an unimpressive twenty-second placing in the Junior. Shortly afterwards,
production of AJR motorcycles ceased.
