2018 Harley-Davidson Street Glide, There s a pride that comes from riding the original, and when it comes to the stripped-down hot-rod look, that would be the Harley-Davidson Street Glide motorcycle. Its style is often copied but has never been equaled. The Milwaukee-Eight 107 engine backs up the look with massive torque. The ride is unmatched as well, thanks to the fully adjustable rear suspension and responsive front suspension and Reflex linked Brembo brakes. You also get a BOOM! Box 6.5 radio that puts out 25 watts per channel.
