Full revelation: MOTORBIKES THAT YOU HAVE NEVER SEEN BEFORE: THE YEAR 1970 SCRAMBLER that is a DUCATI JUPITER 450

The American importer of Ducati, Joseph Berliner, has been a staunch supporter of scrambler-style motorcycles for a very long time. Despite the fact that Ducati was already manufacturing 250 and 350 Scramblers, the American importer specifically requested that Ducati produce a 450cc scrambler. In order for Ducati to accomplish this goal, the “wide-case” crankcases had to be designed in such a way that they permit the displacement to be expanded to 435.7cc. Both the bore and the stroke measured 86 millimeters by 75 millimeters.

For what reason did Ducati USA seek a scrambler with 450cc? The purpose of this is to compete directly with the BSA 441 Victor. The outcome was the Ducati Jupiter 450 Scrambler, a motorcycle that was manufactured in the United States and was manufactured between the years 1969 and 1976. At this time period, the Jupiter 450 was successful in a variety of racing categories, including flat track, enduro, and scrambles.

The engine in question was not a Desmodromic engine; rather, it was an overhead cam engine, and the cam was driven by a tower shaft and bevel gears. In place of the additional rocker arms that are present in a Desmo, the valves are really closed by hairpin springs. The sump contained the oil, so there was no need for an additional oil tank. Models were manufactured with displacements of 250cc, 350cc, and 450cc respectively. The “Jupiter” name was a donation from the United States (USA). The Jupiter stood out from the crowd thanks to its bike, which was bright yellow and had chromed side panels on the tank.

Although it weighed 293 pounds, it possessed the customary handling of a Ducati and was rather light for the day. It featured a five-speed gearbox, but it had a lot of torque in the middle of the range. The Dell’orto square slide concentric was used for the carburetion process. The components of the suspension were manufactured by Marzocchi. There was a retail price of $899 for the item.

The 1971 Ducati 450R/T Desmo was a sales failure for a number of reasons, including the handling of the motorcycle and the timing of the debut of the four-stroke engine, which unhappily coincided with the two-stroke boom that occurred in the late 1960s and early 1970s. Sales were a failure for the motorcycle.

Following the success of the Jupiter, Berliner Motors made a request for a 450cc motocross version that was more accurate to the real thing. The 1971 Ducati 450 R/T Desmo was the product of this endeavor. Additionally, it was constructed solely for the market in the United States. There was no problem with the 436cc four-stroke engine. The bike, which was quite similar to the Jupiter, weighed close to 300 pounds, despite the fact that it produced a horsepower of 38. It wasn’t until 1971 that the Ducati 450 R/T Desmo would be brought into the United States of America. It had a terrible sales performance, with fewer than 200 copies being sold.
