1974 bultaco pursang 2503/21/2024 ![]() Because of the crankshaft’s extra width, there is only one ball bearing on each side instead of two. The increase in displacement came from stretching the stroke 4mm.out to 64mm. The piston, at 83.7mm, is only 0.5mm larger than the one on the 326. The connecting rod rides on roller bearings at the crankpin, and on needles at the wristpin. Inside the same basic crankcase castings as before^ you’ll find crankshaft flywheels that are wider and larger in diameter than those of the 326. And second, adding weight to this machine is as easy as adding something minor-like a skid plate.Īlthough a totally new machine for Bultaco, the Pursang does utilize some components from the 326 Pursang that^fc replaces. First, while not perfect, this bike is capable of accomplishing the aforementioned if you are. However, those of you who are sure that this year you’re going to be banging berms with Pomeroy, DeCoster, Weil and company, should take heart. Most of you will end up in the beginner less-than-five-races left-handed blister-on-your-big-toe class, in which they don’t care whether your knobbied Honda 300 Dream weighs two pounds or two tons. You see, while it may be illegal for FIM (and, consequently, FIM-approved AMA) motocrosses, how many of you are going to buy one to ride in those races? We thought so. for 500cc class) motocross,” you say? You’re right, but that isn’t going to keep Bultaco from selling every last one of these trophy-hoarding featherweights. ![]() with a dry fuel tank? “But that’s under the FIM weight limit (209 lb. Guess who’s getting in on the weight race, but on more legitimate footing this time around? That’s right, friends, Bultaco.Īnd guess what the new 360 Pursang Mark VII (alias the 352 Jim Pomeroy Replica) weighs? Wrong. Both the 250 and 450 Kawasakis weighed in at under 220 lb. The YZ Yamahas, the Husqvarna 250CR (a magnesium and chrome moly rocketship that we tested last month), and the Montesa 250 VR, for example. In the middle of 1973 and in early ’74, some truly light machines have seen their way to dealers’ showrooms. If you know where to look for such things, you may have noticed that everybody else’s bikes were suddenly getting lighter and lighter, as well, and in the middle of a production year! Well, at least the ads said they were lighter. The Hondas were advertised as light, very light, and they were. The introduction of the Honda Elsinore series brought> buyer attention around to another crucially important aspect of motocross bikes-weight. A manufacturer is no longer ashamed to admit that his 250 MX can’t even reach, let alone break, the 30 hp figure, because he knows that no one else’s 250 MX can do it either. Most of the factories stopped releasing such info soon after this decree, but little by little they’ve begun releasing more realistic figures. Then, the government said that if you’re going to print hp figures, you’d better be ready to back them up. Inįact, they got so bad at it that several people began referring to Spanish hp ratings (Montesa was also culpable, as was Ossa, although to a lesser extent) as ponies rather than horses. And, as much as we like Bultacos, we must admit that they haven’t been the most innocent in this respect. Everywhere you looked in motorcycle-related brochures or publications, there they were-the Orientals and the Europeans-all trying to out horsepower one another from the advertising desk rather than from the dyno room. Bultaco Pursangs have continued to leave a mark on the vintage motocross community as they are a popular choice among vmx riders.Look Out DeCoster, Here Comes John Q, Public.įirst it was the horsepower race. He not only became the first American to win on a Spanish bike, but also the youngest rider to win a World Championship Motocross Grand Prix and the first rider to win this type of event in his debut race. Pomeroy became the first American rider to win an FIM international motocross race aboard a Spanish-made bike when he raced a 1973 250cc Pursang in the 1973 Spanish motocross grand prix. Jim Pomeroy was a key player in making the Pursang popular in America. The 1970 Pursang had 9 5/8 inches of ground clearance and had a dry weight of 220.4 pounds. ![]() The back suspension had 5-way adjustable shocks with hydraulic dampening and provided 3 15/16 inches of travel. The front forks had 6 1/2 inches of travel. A 32mm Amal carburetor was used, and the bike had a five-speed gearbox. Pursangs were always known for their power and excellent handling.įor example, the 1970 250cc Pursang had a single-cylinder two-stroke engine with a displacement of 244.29cc and a bore and stroke of 72圆0mm. The leading model in the United States was the 250cc, but Pursangs were built in various engine sizes including 125cc, 360cc and 370cc. The Bultaco Pursang first hit the market in 1965. Bultaco’s main line of motocrossers was the Pursang.
