Harley-Davidson FXSB Softail Breakout is a premium drag bike that mixes premium features, fit and finishes with a wide, muscular, stance and slammed, low-slung power profile inspired by classic Gasser dragsters of the 1950s and 1960s. The Harley-Davidson Breakout model has a stretched, slammed custom style that's low, long and aggressive. It's driven by a powerful air-cooled Twin Cam 103 Harley engine with 6 speed cruise drive transmission that provides more performance power for passing and hill-climbing, and a low cruising RPM for more comfortable cruising. The big, bold Gasser wheels have alternating-position spokes with alternating Vivid Black and machined treatments. The FXSB Softail Breakout model's Gasser wheels recall the powerful, muscular wheels of classic 1960s and 1970s dragster bikes. The H-D FXSB model's Big V-Twin engine has a unique, sharp-looking Vivid Black and Chrome treatment. The massive 240 mm rear tire on the Breakout model is the widest wheel on any Harley production motorcycle.
