The single cylinder 250cc engine in the GB250 started life as a 349cc unit in the early-80s Honda XR350R enduro racer, it was sleeved down to 250cc and fitted with a double overhead camshaft in place of the original single, and then fitted to the new uber modern-looking Honda CBX250.

Some of the traditionalists at Honda felt that the CBX250 could be tweaked slightly to give it a little old school charm, so they set about taking the stock bike and making it into a factory cafe racer – the resulting bike was so universally loved that it was rushed into production with an all new model name – the “GB” referencing Great Britain for its design influences and the “250” for the engine’s capacity.
