All of our stock is imported so this motorcycle will require registration in the UK. All import duties are paid and we provide all necessary import documentation. the bike is registered on the NOVA database. please see below for the simple step buy step guide on how this is done.


Associated Motorcycles (AMC) were the last of the major British motorcycle manufacturers to enter the market with a parallel twin market offer a parallel twin. not revealing the AJS Model 20 and Matchless G9 until the Earls Court Motorcycle Show of 1948 and even then it was destined for export only. The two new machines followed a proven configuration for the power plant. the 498cc OHV engine's design was good from the outset. it was fitted with. the now famous third centre main bearing. it had no external oil lines and alloy heads from the very start.

This new engine was placed in the swinging-arm frame that had recently introduced on AMC?s heavyweight singles. the signature ??jam pot? rear suspension units were fitted from 1951. Unusually for AMC there were significant differences between the two marque?s. each featuring their own individual tanks. seats and exhaust pipes this in addition to the customary badge and colour scheme differences.

We have checked the frame number with the AJS and Matchless Owners club and it has been confirmed to be a 1955 Model 55 / 20.


This is a very handsome motorcycle and cosmetically this machine is in good shape. we believe that probably had some restoration work at some point in his life. The tank is finished in chrome. we are not certain of the correct pattern for the year but we believe that the tank would originally have had black panels. The are no dents and the chrome is clean and rust free although it has dulled a little over the years. particularly around the fuel cap. There is a small area on top of the tank toward the front where the chrome is lifting a little and has some small chips.  

The tool boxes are in good order with no signs of corrosion inside or out and are fitted with the correct knurled fasteners. The oil tank is also in good shape with no dents or damage.  

The rear mudguard is also clean and in good order. the front guard is clean and undamaged. it does have some small scrapes and chips in the paint. we believe that both are correct and original. The seat cover is in good condition. we are not sure if it is original but it certainly has a nice patina of well cared for age which fits well with the overall appearance of the bike as a whole.

The exhaust system appears to be the original the chrome is clean and in good order although it does have some age related minor marks. The wheels are very clean. the chrome on the rims is bright. the spokes do have some light surface corrosion. this is purely cosmetic.   


We have had the engine fired up and taken it for a short test ride. it starts easily and runs well. the engine oil is circulating and returning as it should. The bike does smoke when started and is a little mechanically noisy. while the smoking is tails off as the engine warms it will require attention. we would recommend budgeting for freshening up the top end. a straightforward exercise on these push rod motors.

The clutch is dragging a little and will require adjustment. as this causes the gear changes to be rough we have performed a static check through all gears. all select well.  

The kill button is not working. The engine cases are clean with no sign of accident damage.  


The chassis and cycle parts are in very good shape as can be seen in the photographs. The frame and swinging are in good order. the paint we suspect has been refinished.  

The front and rear brakes both work as they should. On the suspension side. the fork action is smooth and the damping effective. the rear shocks are very clean and again damping well.

The handlebars have been replaced with narrow bars and this has led to some overly tight cable routing. the throttle cable has suffered in particular. and is badly kinked. this will need replacing as the revs on the bike are slow to drop.  


The ignition system is working well. the bike starts well. the battery is unserviceable and will require replacement. with a slave battery the headlight works on high beam. dip is out the rear light works. as does the rear brake light although the switch will need adjustment. The bike is not fitted with indicators.  

The switch gear is fitted and in good order. the bike retains its original instrument. this are in good order and working.  


This Ajay is a very nice example while it will undoubtedly need some work to return it to the road this work should prove straightforward. There is no doubt that the top end of the engine will need some attention shortly. This is a bike that would form a leisurely way to spend some winter evenings; it is a complete and running machine that is largely original and unmessed with. This is a very handsome machine that will reward a little effort with very practical. rare and sought after classic motorcycle.  

As it predates 1960. this bike will not require an MOT and will benefit from free road tax.
