Although various pre-war Nortons had been available to special order in trials specification, or 'Colonial' as they quaintly described them in the 1920s, it was not until 1948 that a purpose built machine was offered in the range. The new 500T used the engine as fitted to the model 18 and ES2, a 16H diamond frame with roadholder forks up front, these raked sharply to reduce the wheelbase. The engine had an alloy cylinder head and barrel along with lightened parts elsewhere, reducing the overall weight to 300 lbs. The earliest examples had a high level exhaust system, but by late 1949 it had been lowered with an upswept silencer. The 500T was competitive in its day and enjoyed some successes before it was discontinued in late 1954.
Norton has long enjoyed a unique place in motorcycle history. The Norton trials bike is an important part of that history. This classic trials bike is described by the vendor as being in tremendous order. The bike is offered at auction with a current V5C registration certificate and is offered at no reserve
