2015 AJS EOS 125Edit


The 2015 MY AJS EOS 125 sports a liquid-cooled, four-stroke, 124cc, twin cylinder powerplant mated to a five-speed manual transmission, and can reach a maximum power output of 11 horsepower at 9500 rpm. It also comes standard with a raked-out front end, a hardtail rear suspension with a hidden monoshock, chrome-plated, forward-mounted foot controls, chrome engine covers, aluminum alloy wheels, dual front disc brakes, a telescopic front fork and a wide handlebar.


The AJS EOS DD125E-5 is probably the most eye-catching bike we sell; it has extended forks for the full chop look, giving a massive 1860mm wheelbase. Allied to this is the soft-tail suspension at the rear - this means that the twin rear shocks are hidden under the engine, giving it the look of a hard tail. The full chopper/cruiser look is underlined with a full feet forward riding position and flat bars on chrome risers. The simple instrumentation is built into the tank to keep the lines clean and uncluttered. The EOS 125 is powered by the AJS 125 liquid cooled, twin cylinder, single overhead cam (SOHC) four stroke engine now with balancer shafts. It comes in either traditional black, or black with silver flames on mudguards and tank, plus plenty of good quality chrome to catch the light and shine out like the outrageous custom bike that it is. If you are looking for staid, no-nonsense, low cost commuting then look at other bikes we have - the EOS is an out and out head turner for those who want to cruise in great style. Get this great machine out on the road and enjoy life.
