Colin Seeley used his racing background and his extensive knowledge of motorcycles to design and built bespoke motorcycle frames for racing. During the late 1960s and early 1970s Seeley frames were used by many privateer racers with notable successes in both GP and the IOM TT races with such riders as Giacomo Agostini and Barry Sheene. Many of the designs used the engine as a stressed member adding strength and rigidity which resulted in much lighter frames with superior handling. This genuine Seeley Bonneville has the added bonus of having a rebuilt 1971 unit construction T120 engine with a 180° crank. This means that the pistons move in a ‘boxer’ like firing motion. Behaving more like a V Twin engine this vastly alters the power and sound which is quite amazing !

In excellent overall condition this bike has had little use in recent years having resided in several private collections. Fitted with many other very special parts; a massive Oldani four leading shoe front brake, Norton Roadholder forks, Mikuni carbs, Seeley bespoke hubs and Boyer electronic 12v ignition. In addition the bike also comes with a full front fairing with a light unit should you wish to change it from its current cafe racer configuration. Having recently been recommissioned for the road it is supplied with a UK V5C registration document and MoT.

Recent investigation of the frame has revealed the genuine Seeley number 318 K. Colin Seeley’s own records show that the frame was one of five built, this one specifically for South African born double World 250 and 350cc Champion Kork Ballington, hence the K in the frame number Sold in 1972 the bike was originally fitted with a Kawasaki 500cc H1 and later an H2 engine, pictures of this bike are featured in the publication ‘Ballington Unkorked’, it campaigned in South Africa and Europe with notable success. The bike is now the subject of a three page article in the May issue of Classic Bike magazine and is a fantastic opportunity for someone to convert this machine to its original specification.
