The Harley Davidson motorcycle engine is typically a two cylinders, v-twin. The engine was originally designed with some flaws and was designed to operate without a distributor to cut down on costs. A Harley-Davidson motorcycle has been revamped over the years but it has retained its V-twin style engine. Though the design of the engine as initially produced to cut down on the money it took to produce the engine, it inadvertently created one of the most famous aspects of the Harley motorcycle, its sound. Today the engine has been perfected to keep its shape and sound and run like the champ it is. The pistons on the v-twin are at a 45 degree angle and this design has been known to make the pistons fire at uneven times.
In order to rectify the problem the engine was designed to run with a single set of points and so the first cylinder fires initiating the power stoke and then the second fires when the exhaust valve is open. This is produced because of the angle and it subsequently produced the distinctive sound of the Harley. As engineering advanced the design of the Harley engine was kept mostly the same. The design of the engine had created a sound that endeared the Harley motorcycle to its fans. Because of the love of the sound that the angle of the engine produced Harley’s are recognized all over the world. The sound of a Harley echoes round the world and the Harley Davidson Company has tried unsuccessfully to patent the sound. Even though they were unsuccessful at their trademark application the company has succeeded in making their brand a status symbol desired by people all over the globe. The sound of the original “flawed” engine is still a sound that turns heads today. It is a trademark of a company that has built its reputation on the quality and excellence of its products.
