Engine & Performance for the 2020 Harley-Davidson FLHX Street Glide

The 2020 Harley-Davidson FLHX Street Glide features Engine: Milwaukee-Eight 107 V-Twin, Displacement: 1,746 cc (107 cu in), Cooling: Air/Oil Cooled. This trim includes Chrome Finishes — The standard FLHX features chrome engine covers, exhaust, and trim, unlike the blacked-out Special model.; Milwaukee-Eight 107 — Powered by the 107ci engine; the Special and CVO models receive the 114ci and 117ci versions respectively.. Owner note: Requires ~4.5-5.0 quarts of 20W-50. Check hot on the jiffy stand to avoid overfilling, which causes oil carryover into the air cleaner. Known concern: Oil Sumping — 2020 models received an updated oil pump (seal on the back) that significantly reduced this issue compared to 2017-2019 models.. Learn more about this ride →
