2008 Harley-Davidson FLHX Street Glide
About the 2008 Harley-Davidson FLHX Street Glide
The 2008 Harley-Davidson FLHX Street Glide is a 'factory custom' bagger that bridges the gap between the classic touring capability of the Electra Glide and a more stripped-down, hot-rod aesthetic. This specific year is a significant 'transitional' model, as it represents the final year of the classic touring frame while introducing major modern upgrades like a 6-gallon fuel tank, Brembo brakes, and Electronic Throttle Control. It is powered by the 1584cc Twin Cam 96 engine and a 6-speed Cruise Drive transmission.
What Makes This Trim Special
- 6-Gallon Fuel Tank — New for 2008, replacing the 5-gallon tank used in previous years.
- Brembo Braking System — High-performance dual front and single rear 4-piston calipers replaced the previous Hayes-style brakes.
- Electronic Throttle Control (ETC) — Introduced 'fly-by-wire' technology, eliminating physical throttle cables.
- Isolated Drive System (IDS) — A rubber-dampened rear hub designed to reduce noise and vibration from the 6-speed transmission.
- 105th Anniversary Edition — Optional trim featuring Copper and Vivid Black two-tone paint and serialized badging.
Likely but unverified:
- Optional ABS — 2008 was the first year ABS was offered as a factory option on civilian touring models.

Moisture in old brake fluid causes the ABS valves to stick, resulting in a loss of braking pressure or a hard lever.

Weak springs in the stock compensator cause harsh engagement and 'starter kickback' during starts.
