It was in 1958 that Associated Motorcycles announced the AJS Model 14 and Matchless G2, ostensibly a new range of unit construction 4-stroke 250s; the market reacted unenthusiastically. The engine was bulky for the quarter litre class and, on closer examination, still used a separate gearbox, requiring manual adjustment of the primary chain. The fact the chassis employed similar components to the James & Francis Barnett lightweights also drew further adverse comment. Half a century later these models are understandably rare, and it is correct to state they now possess a certain appeal for serious students and/or collectors of the evocative AMC brand. With its unusual gold and black livery, enhanced by the 350/500 type forks [per CS specification], it is a visibly attractive machine.

Reviewsummary

" The machine is very good for a learner or someone who just wants to potter towork. But for a more serious motor cyclist like myself it is ruined by smalldesign faults which could easily have been rectified by the makers.

" For long distances, adjustable handlebars and controlswould make an incredible difference. However, this particular fault has at lastbeen attended to."

That quotation is from Chris Gilbert. And it is fairlyrepresentative of the opinions of all reporters. Confirmation comes from19-year-old machinist Barry Heywood, of Coventry: "One of the best two-fiftieson the market. You get what you expect for your money. And now that they havefitted new forks and brakes and given it a face lift, the Matchless Sports isbetter than ever. If I was going back to a quarter-litre job, I would haveanother CSR any day."

" The acceleration, braking and road holding will match anyBritish two-fifty. It must be the most beautiful motor cycle in the world." IanSpooner of Chesterfield speaking.

Postscript is added by Michael Weaver: "A good littlebike—nothing elaborate or fancy."Thereyou have it. The AJS and Matchless two-fifties are fast, comfortable and fun toride. Unless you happen to be very unlucky, they are also reliable.
