2008 Harley-Davidson FLHX, 1584CC.

The 2008 Harley-Davidson Street Glide (FLHX) represents a pivotal year for this iconic "hot-rod" bagger. Known for its slammed look and minimalist styling, the 2008 model introduced several massive mechanical upgrades—including a larger fuel tank and improved braking—that transformed it from a stylish cruiser into a truly capable long-distance machine.
Significant 2008 Upgrades
New Fuel Capacity: This was the first year for the 6-gallon fuel tank, significantly extending your range between stops compared to previous 5-gallon versions.
Precision Braking: 2008 introduced the Brembo® 4-piston caliper braking system. It also marked the first year that ABS became an available factory option for this model.
Throttle by Wire: The introduction of Electronic Throttle Control (ETC) cleaned up the handlebar aesthetics by removing external cables and paved the way for smoother cruise control operation.
Performance & Style
Engine: Powered by the Twin Cam 96™ V-Twin engine (1584cc) with Electronic Sequential Port Fuel Injection (ESPFI).
Transmission: Features the 6-Speed Cruise Drive® transmission, providing a quiet, low-RPM overdrive gear for highway speeds.
Street Stance: Defined by its "slammed" rear suspension, chopped smoked windshield, and fairing-mounted mirrors, giving it a lower profile than the standard Electra Glide.
Audio: Comes standard with the Harman/Kardon® Advanced Audio System, integrated into the classic Batwing fairing.
