Engineering Highlight: The FXSE Breakout Pro Street represents a pivotal moment in Harley-Davidson’s Custom Vehicle Operations (CVO) history as the first production model to prioritize ‘dark custom’ aesthetics over traditional chrome, introducing the industry-first ‘Smoked Satin Chrome’ finish. This process involves a meticulous multi-step plating technique that provides a brushed, industrial look while maintaining the corrosion resistance of high-grade chrome.
Technical Overview: The Screamin’ Eagle 110B
At the heart of the FXSE is the air-cooled Screamin’ Eagle Twin Cam 110B engine. Unlike the standard Twin Cam engines found in the Dyna or Touring lines of that era, the ‘B’ designation signifies internal counter-balancers. This was essential for the Softail chassis, where the engine is rigid-mounted to the frame. The 110B delivers a massive 151 Nm (111.4 ft-lb) of torque at 3,500 RPM, providing the aggressive ‘stoplight-to-stoplight’ acceleration the Breakout is known for.
Chassis and Suspension Architecture
The Pro Street variant differs significantly from the standard Breakout (FXSB) through its race-inspired front end. It features 43mm inverted forks held by a massive three-bolt triple clamp. This setup increases torsional rigidity, significantly reducing fork flex during heavy braking or aggressive cornering—a necessary upgrade given the bike’s 332 kg (732 lbs) wet weight and dual front disc brakes.
Maintenance Guide: Keeping the FXSE at Peak Performance
Lubrication System
To protect the high-lift cams and hydraulic lifters of the 110B engine, MotoSpecsLab recommends the exclusive use of Harley-Davidson SYN3 Full Synthetic 20W-50. The system requires 3.3 liters. Frequent oil changes every 5,000 miles (8,000 km) are critical for air-cooled engines operating in high-traffic or high-heat environments.
Ignition and Electrical
The FXSE utilizes Harley-Davidson 6R12 spark plugs. For optimal combustion efficiency, the gap must be precisely set between 0.97 and 1.09 mm. The electrical system is anchored by the 65989-97D battery, which provides the high cold-cranking amps required to turn over the high-compression 110-cubic-inch V-twin.
Tires and Traction
The signature look of the FXSE is its massive 240mm rear tire. Maintaining correct pressure is vital for handling; a drop in pressure on a tire this wide will cause the bike to ‘track’ on road grooves and resist leaning. Always maintain 42 psi (2.90 bar) in the rear and 36 psi (2.48 bar) in the front 130/60B19 tire.
Editor’s Verdict
The FXSE Breakout Pro Street is more than a styling exercise; it is a precision-engineered drag bike for the street. While its turning radius is limited by the wide rear tire, its straight-line stability and build quality remain benchmark for the CVO division. For the collector or the enthusiast, it remains one of the most aggressive Softails ever produced.
