AJS 1915 “Model D” 750 cc side valve V-twin engine # 6784
The four Stevens brothers had been in motorcycle manufacturing since the final years of the 19th century, but only in 1911 their first complete “AJS” motorcycle, a 298 cc twospeeder, was marketed.
For the 1912 season their first V- twin, the model D, was brought out.
In the 1914 Junior TT a magnificent first and second place was scored.
The company moved to new premises at Graisely House, Wolverhampton.
The 1915 range consisted out of three models; the sporty 2 ¾ HP single, a medium weight 4 HP ( 550 cc) twin and as top of the range the 6 HP model D.
A new feature on all 1915 models was the so called “AJS scientific frame” with straight top tube sloping from head to seat lug, eleminating the use of bent tubes.
Brampton patent spring forks were used on the model D; it also features a state-of-the-art three speed countershaft gearbox and internal expanding rear brake.
Note the American Splitdorf magneto, a feature found on many World War I British machines due to the non-availability of Bosch magnetos. This well-constructed machine has been restored some 20 years ago and comes complete with acetylene lighting system and bulb horn.
