Harley-Davidson 114 CI. Black version
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 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 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.
107 and 114 and 117 engines
All engines have eight valves in two cylinders in the traditional Harley-Davidson Radial V-twin configuration at 45°, are combination of air-cooled and oil-cooled, and activate valves with push-rods. The 107 cu in (1,750 cc) model with a claimed 108–112 lb⋅ft (146–152 N⋅m) is standard on all models, with the 114 cu in (1,870 cc) 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 117 cu in (1,920 cc) 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.
