<P> The Harley - Davidson Milwaukee - Eight engine is the ninth generation of "big twin" engines developed by the company, but only Harley's third all - new Big Twin in 80 years, first introduced in 2017 . 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 also marked a return to the single - camshaft configuration as used on previous Harley Big Twin Engines from 1936 to 1999 . In addition, the engines all have internal counterbalancers, whereas Twin Cams were counterbalanced only on Softail models, where the engine was rigidly mounted . </P> <P> All engines have eight valves in two cylinders in the traditional V - twin configuration at 45 °, are combination of air - cooled, liquid and oil - cooled, and activate valves with push - rods . The 1,746 cc (107 cu in) model with a claimed 108--112 lb ⋅ ft (146--152 N ⋅ m) is standard on all models, with the 1,868 cc (114 cu in) version making a claimed 119 lb ⋅ ft (161 N ⋅ m) remaining as an option on some softails and all touring and trike models, and the 1,923 cc (117 cu in) is standard on CVO models with a claimed 124 lb ⋅ ft (168 N ⋅ m) and rear wheel power of 93.75 hp (69.91 kW) @ 4,870 rpm and 112.51 lb ⋅ ft (152.54 N ⋅ m) @ 3,400 rpm . </P> <P> As of 2016, the Milwaukee - Eight engines are only available on Touring and Trike models of the 2017 model year . The most significant change from the Twin Cam are the two extra valves per cylinder head which produce 10 percent more torque . The exhaust and intake flow capacity is increased by 50 percent over the Twin Cam models . Although weighing the same as its predecessor, both models of the Milwaukee - Eight increase in acceleration by 10% (0 - 60 for the 107 vs the 103) and 8% (0 - 60 for the 114 vs. the 110). Fuel economy is also increased, with percentages varying for engine and model . </P>
