Engine & Performance for the 2018 Harley-Davidson FLHX Street Glide

The 2018 Harley-Davidson FLHX Street Glide features Engine: Milwaukee-Eight 107 V-Twin, Displacement: 1,746 cc (107 cu in), Cooling: Air-cooled with precision oil-cooled cylinder heads, Fuel System: Electronic Sequential Port Fuel Injection (ESPFI). This trim includes Chrome Finishes — The standard FLHX features chrome engine covers, exhaust, and front forks, whereas the FLHXS (Special) is blacked-out.. Owner note: Heavy touring weight (800+ lbs) leads to rapid wear of the 4-piston caliper pads, especially if linked braking is used heavily. Known concern: Oil Sumping — Often resolved by installing the 2020+ updated oil pump (H-D Part #62400247).. Learn more about this ride →
