This example is from the last year of the distinctive “boat tail” seat unit, and it’s a truly wonderful example of Bultaco’s influence on the motocross scene. They had plenty of torque, making constant shifting a non-issue, but best of all, they were really lovely machines with an ultra-slim, beautifully shaped gas tank. Better than simple specs, the Pursang handled beautifully it was forgiving over a variety of racing surfaces and a wide range of riding styles.
It came with double ignition to improve throttle response, the bodywork was altogether much more streamlined despite following the general lines of preceding versions.

The Pursang was the bike to beat in the mid-1970s, and all the other factories tried. The Mk 4 version brings to an end a cycle in the Pursang series. The Pursang has been done up as a replica of the Bultaco 250 that Jim Pomeroy won the 1973 Spanish GP with. It was restored in 2006 and is a complete and correct machine. Pursang was Bultaco motorcycle production between 19, designed specifically for those who practiced motocross. This 1971 Bultaco Pursang MkIV 250 has a dry weight of 220 pounds, 9.625 inches of ground clearance, 6.5 inches of front fork travel and a powerful motor. The Pursang was introduced in 1965, and in common with the rest of Bultaco’s range (barring the water-cooled TSS road racer), it was a single-cylinder, air-cooled, two-stroke machine with a 5-speed gearbox, most popularly (in the U.S.) with a 250cc capacity, although the engine ranged from 175cc to 370cc by merely changing the cylinder/head and exhaust. The factory had already revolutionized trials riding with the Sherpa T under Sammy Miller, and the Astro was the mainstay of indoor short-track racing. They had shapely, extremely thin fiberglass gas tanks that were so thin the head fins stuck out on either side. That race was the whammy Bultaco needed to popularize the Pursang in the United States. Bultaco rewarded Pomeroys continued loyalty to the Spanish brand (despite a flood of offers from other manufacturers) by naming its 1974 Pursang after him. Pomeroy was the youngest rider to ever win such a race, as well as the first rider to win an MX Grand Prix race in his debut event.
In 1973, the Bultaco Pursang shocked the world by carrying motocross racer Jim Pomeroy to the first American victory in an FIM Motocross Grand Prix race on a Spanish motorcycle. The effect Bultaco had on the global MX scene is hard to over-emphasize. The Bultaco Pursang is a legendary motorcycle in enduro and motocross events of the 1970s, and this 1971 MkIV is a terrific example of the breed.
