AJS 1929 M 7 349cc OHC frame # 145021 engine #M 7 / 145021 carburettor AMAC M7-6111 gearbox M7/ 145021
For some 6 years the “ Bigport” series had been very successful, but in 1928 it was decided it was time to give the 1929 model range a totally new appearance.
No less than 20 “ improvements” were made and they were certainly no detail changes.
To name a few: a redesigned frame giving a lower saddle height, a graceful saddle tank with built in speedometer, separate oil tank, enclosed valve mechanism and last but not least brightly colored side panels on the tank.
The Model range spanned from the 9.96 HP twin passenger combo ( M1) to the 2.48 HP lightweight ( M12); AJS started numbering with the highest capacity models, which was rather unusual with model numbering systems then.
Three models represented the 350 cc class: M6 in single and double port versions, and M7 that sported an OHC engine.
This machine has a chain driven OHC engine with patent tensioning device and reaction damper and it was marketed as an “over the counter” racing machine.
Some of the special features are : TT-type handlebars, twist grip carb control, narrow racing-type mudguards and close ratio gearbox.
The rear wheel has been fitted with a specially light hub and brake drum and a Smith speedometer has been fitted in the tank top.
This rare machine was originally sold in Dresden, Germany.
It comes in original, unrestored condition and has a lovely patina.
