Lot 383 - 1976 Bultaco Pursang Mk. IX
|Estimate||£4,500 - £5,500|
1967 saw the introduction of Bultaco's famous Pursang motocross model, which continued in production until 1981 with the ultimate Mk 15 edition.
The story of Bultaco motocross machines starts in 1960 when company founder Francis Xavier Bulto engaged top British riders, Derek and Don Rickman, to try a 175ccTrallaspecial he had prepared for the Circuit de Pedralbes. The brothers liked the engine, but not the chassis. Despite his misgivings Don won the race and an agreement was reached whereby the Rickman brothers would build their own chassis to house the Bultaco engine.
The result was the 250cc Bultaco Metisse which made its debut in 1964 and which was also known as theMestizo -the Spanish translation of Metisse, meaning 'of mixed blood'. The Rickman brothers built machines for the UK market while Bultaco built those to be sold elsewhere. Unfortunately, there were soon reports of the Spanish frames breaking as they were made of tubing inferior to that of the Reynolds 531 specified by the Rickman brothers. The agreement was curtailed in 1967, with the Rickman brothers unable to keep up with demand for their Metisse machines and so Bultaco introduced their own, simpler frame with a single down tube, as opposed to the duplex arrangement of the Rickman design. The new model was named the Pursang ; 'thoroughbred' in French, on account of its being manufactured entirely by Bultaco and despite their agreement having been broken Don Rickman gave the Pursang his seal of approval, successfully racing examples over several seasons.
Initially only available as a 250, by the time the Mk 5 was introduced in 1971 there were additional engine options of 125cc and 350cc. With the following year's Mk 6 version, the range had expanded to include 175cc and 200cc versions too and the Pursang had become the world's best selling motocross machine. The Pursang achieved great success accumulating thirteen Spanish Motocross Championship titles in addition to seven in France, four in Great Britain and one in Italy.
This Pursang Mk 9 dates from 1976 and features a 250cc single cylinder motor producing 34 bhp. It has been completely rebuilt and now benefits from the fitment of Dyno Power electronic ignition. It has the standard five speed gearbox and weighs just 98.5 kgs dry. The Pursang has been in a private collection since 2011 and importantly, the chassis and engine numbers are matching, something rarely found with classic competition bikes. Finally, the outstanding feature of this Bultaco is the signature on the petrol tank, that of Sammy Miller, whose name is inextricably linked with Bultaco having developed and successfully ridden the Sherpa trials model.
