The AJS H6 production version was launched in November, 1922, and soon acquired the 'Big Port' nickname because of its large exhaust port and pipe. Its right-first-time, racer-on-the-road design meant that it was ridden to achieve countless sporting successes in the hands of privateers and it underwent only minor detail changes until it was superseded by the much-revised M6 model in 1929.

For many years, this particular example was in the collection of the late Jim Noble of North Leeds, UK. It is to original specification with acetylene lighting, a generator, a Cowey speedometer, a Lagrande leather saddle, a luggage carrier and two panniers. It was acquired for the NZ Classic Motorcycles collection via a UK auction house from a private vendor in Ripon, Yorkshire, in July, 2009.
