Harley-Davidson Twin Cam engine at the Harley-Davidson Museum. The Harley-Davidson Twin Cam are motorcycle engines made by Harley-Davidson from 1998 to 2017. Although these engines differed significantly from the Evolution engine, which in turn was derived from the series of single camshaft, overhead valve motors that were first released in 1936, they share a number of characteristics with ...
The Harley-Davidson Milwaukee-Eight engine is the ninth generation of "big twin" engines developed by the company, but only Harley's fourth all-new Big Twin in 80 years, first introduced in 2016. These engines differ from the traditional Harley Big Twin engines in that there are four valves per cylinder, totaling eight valves, hence the name.
In 2007, Harley-Davidson introduced the 96 cubic inches (1,570 cubic centimetres) [140] Twin Cam 96 engine, as well the six-speed transmission to give the rider better speeds on the highway. In 2006, Harley introduced the FLHX Street Glide, a bike designed by Willie G. Davidson to be his personal ride, to its touring line.
Harley Davidson "is engaging in a rather risky PR strategy," Morgan Stanley said Friday. The motorcycle brand this week pushed back on President Donald Trump's quickly intensifying trade war with ...
In 2007, the Twin Cam 88 engine was replaced by the fuel-injected 1584 cc Twin Cam 96 engine across the entire Harley-Davidson Big Twin lineup, including the FXD series. The 'I' model designator was dropped for all models, since all Big Twins from then on had fuel injection. [citation needed] The FXDF Fat Bob was introduced in 2008.
The Shovelhead engine is a motorcycle engine that was produced by Harley-Davidson from 1966 to 1984, built as a successor to the previous Panhead engine. When the engine was first produced, the Shovelhead had a shallower combustion chamber, larger valve drop for both intake and exhaust, better porting, and stronger valves and pistons.
That first engine was a single cylinder model, based on the French developed De Dion-Bouton internal combustion engine. The company was soon fully committed to producing its own proprietary engine designs, and by 1909 the first Harley-Davidson V-Twin engine had been designed and made, setting a template for engine design that continues today.
Harley-Davidson's official name for the engine was likely related to the company's attempt to reform its image following the 1981 management buyout from previous owner American Machine and Foundry (AMF).
