2018 Harley-Davidson Street Bob® 107


Straight-up, two-fists-in-the-wind attitude and no extra fat are the ingredients that went into the all-new, blacked-out Street Bob® motorcycle.

Styling + Features

  • STRIPPED-DOWN, RAW BOBBER STYLE: Features mini-ape handlebars, laced wheels, and dark finishes. It’s a personal revolution rolling on spoked wheels with chopped fenders.
  • ALL-NEW SOFTAIL® FRAME: A lighter, stiffer frame (now 17 pounds lighter, quicker and stronger 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 hardtail from a bygone era that delivers a thoroughly modern ride.
  • MILWAUKEE-EIGHT® 107 ENGINE: A powerful, smooth-running Big Twin engine with crisp throttle response and a pure, soul-satisfying rumble.
  • MINIMALIST, MODERN TECHNOLOGY: You get digital instrumentation, keyless ignition, a USB charging port, and Signature LED forward lighting.
  • HIGH PERFORMANCE FRONT SUSPENSION: New Showa® SDBS® 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 while preserving the hardtail look.
