The 2020-2021 Softail Slim continued the Milwaukee-Eight version introduced in 2018, with the 107 cu in engine, hidden monoshock and a 49 mm cartridge-style fork under 'beer can' covers. It kept its post-war bobber styling: laced wheels, chopped fenders, floorboards and a low solo seat. Harley quoted 110 ft-lb of torque, and braking used a single 300 mm front disc with a four-piston caliper.
