The engine design differed considerably from its predecessor the "Evo" although it shared some design elements with the Sportster line. The 88 represents the displacement in cubic inches of the standard engine. The bore is 3.75 in (95 mm) and the stroke is 4.00 in (102 mm), meaning the displacement is 88 cu in (1,450 cc).
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.

Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
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.
It was one of Harley-Davidson's attempts to enter the small displacement off-road motorcycle market. It was built in Aermacchi's Varese , Italy factory. It had a 98 cc (6.0 cu in) two-stroke , single cylinder engine with five speed transmission, derived from the current two-stroke production, mostly Aletta and Aletta d'Oro off the shelf parts ...
The Hummer was added to Harley-Davidson's model line in 1955. It was a stripped-down basic model using a redesigned "B-model" engine with the old 125 cc capacity. It was named after Dean Hummer, a Harley dealer in Omaha, Nebraska who led national Harley two-stroke sales. [2] The Hummer was as basic as it could have been.
The Panhead engine replaced the Knucklehead engine in 1948 and was manufactured until 1965 when it was replaced by the Shovelhead. As Harley-Davidson engines evolved, the distinctive shape of the rocker covers led Harley enthusiasts to recognise an engine simply by identifying the head, with names such as "Flathead", "Knucklehead" "Panhead ...
