The Matchless G9, and its twin brother, the AJS Model 20, were produced from 1949 to 1961 according to the Owners’ Club website. These 500 twins were rarer than their 500 single counterparts and give a smoother ride. This smoothness comes from the famous 498cc OHV engine which featured an alloy head from the beginning. They will happily cruise at 60mph, with the later bikes, from 1958, featuring the famously fine AMC four-speed gearbox.
Our bike is a 1959 model, which has recently received a full restoration from a local enthusiast. The work undertaken includes a full engine and gearbox rebuild, as well as a new exhaust system, fresh paint and a new rear tyre. Of particular interest is a special valve fitted to the lubrication system to prevent wet sumping. This valve is connected to the ignition system so that the bike cannot be started when the valve is in the closed position, to avoid running the bike with no oil circulating.
We have carried out a full check on the bike following restoration to ensure that it is tuned and ready to ride. This is a great opportunity to acquire a lovely G9 in superb condition ready to show or ride, the choice is yours.
