2018 Harley-Davidson Softail Slim® 107


A raw, vintage H-D style, with a modern edge. The all-new Softail Slim® motorcycle is 35 pounds lighter than last year’s model, with more power, more lean angle, and a redesigned suspension.

Styling + Features

  • DARK POLISHED FEATURES: Features blacked-out metal from the Hollywood handlebars to the black steel laced wheels.
  • LOW-SLUNG TUCK-AND-ROLL SEAT: A low-slung solo saddle that matches the bike's clean, back-to-basics attitude, setting you "in" the bike so you ride like you're a part of it and the open road ahead.
  • MILWAUKEE-EIGHT® BIG TWIN ENGINE: A powerful, smooth-running engine with crisp throttle response and a pure, soul-satisfying rumble.
  • ALL-NEW SOFTAIL® FRAME: A lighter, stiffer frame (compared to previous Softail® and Dyna® models) that takes the idea of form and function to a place it's never been before. It's the look of a hard tail from a bygone era that delivers a thoroughly modern ride.
  • SIGNATURE LED FORWARD LIGHTING: Darkness-defying lighting that give you greater visibility at night.
  • HIGH PERFORMANCE FRONT SUSPENSION: New Showa® SDBV® suspension technology provides the performance of a racing-style cartridge fork for reduced weight with linear damping characteristics.
  • HIGH PERFORMANCE REAR MONO SHOCK: All-new easily adjustable mono-shock rear suspension allows for dynamic cornering capability, quicker acceleration and braking while preserving the hardtail look.
