AJS 1915 550cc 2 cyl sv



AJS  1915    550 cc   Model A side valve  V-twin     frame# 291  engine# 5872

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, the  medium weight 4 HP ( 550 cc) twin  model  A  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, eliminating the use of bent tubes. 
This gives the petrol tank a slightly wedged- shaped appearance.  Brampton patent spring forks are used on both V-twin models. 
Some other features are:  three speed countershaft gearbox, completely enclosed chains and internal expanding rear brake. 
An American Splitdorf magneto takes care of the ignition: the Bosch magneto was not available anymore for British manufacturers. 
This  charming machine is an older restoration and the machine is in excellent shape. 
It comes complete with acetylene lighting and bulb horn.
