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.
The Twin Cam 96B engine was released at the same time as the Twin Cam 96A model, for the 2007 model year, and was equipped on all Softail models until it was replaced by the 103 ci version. [8] It is however possible to mount a regular Twin Cam motor to a pre-2000 Softail (or any chassis that accepts an Evolution engine) through third-party ...

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.
Valvetrain problems in early Knucklehead engines required a redesign halfway through its first year of production and retrofitting of the new valvetrain on earlier engines. [39] By 1937, all Harley-Davidson flathead engines were equipped with dry-sump oil recirculation systems similar to the one introduced in the "Knucklehead" OHV engine.

The Fat Boy was one of numerous Harley-Davidson models built on the Softail frame. After 1994, the exhaust was made seamless. In 1996 the master cylinder and switch gear were revised. In 1999 a new 1,450 cc (88 cu in) Twin Cam engine for the 2000 model year was used. This necessitated a bespoke engine variant and changes to the frame.
The engine was mounted directly to the frame from 1957 through the 2003 model year. While this system allows the bike to be somewhat lighter with more precise handling, it also transmits engine vibration directly to the rider. In 2003, Harley Davidson produced a limited number of 100th anniversary model Sportsters.
