With Phil Aynsley


Suzuki’s original entry into the 500cc class came in 1968 in the US with the XR-05. The motor was a modified unit from the T500 Titan/Cobra road bike.

It wasn’t until 1971 that the XR-05 appeared in Europe with Aussie Jack Findlay winning Suzuki’s first 500cc GP at Ulster that year. Output had risen from 63 to 71 hp over the intervening years.

The XR-05 Mk III filled the gap before the introduction of the RG500

In 1974 the MkIII arrived as an interim model, intended to be used until the new RG500 square four was available. The MkIII had revised cylinders with a squarer look and laid down rear shocks.

Square cylinders were a point of note on this model

Only 15 MKIII’s were constructed with the bike seen here number 15. This bike has been fully restored although all the paintwork is original apart from the fairing. Care was taken to use as many original parts as possible.
