2015 Harley-Davidson FLHR Road King
About the 2015 Harley-Davidson FLHR Road King
The 2015 Road King is a classic-style touring motorcycle that benefited from Harley-Davidson's Project RUSHMORE enhancements, combining vintage aesthetics with modern performance. This model year is notable for the introduction of the High Output Twin Cam 103 engine and the transition to a hydraulic clutch for the Road King line. It serves as the 'stripped-down' touring option, featuring a detachable windshield and hard saddlebags without the heavy fairings found on the Street Glide or Ultra models.
What Makes This Trim Special
- Hard Saddlebags — Injection-molded hard bags with One-Touch latches for easier opening. (Street Glide, Electra Glide)
- Impeller Cast Aluminum Wheels — 17-inch front and 16-inch rear 10-spoke wheels.
- Hiawatha Headlamp — Large 7-inch chrome headlamp nacelle with dual halogen bulbs.
Likely but unverified:
- Reflex Linked Brakes with ABS — Often bundled with the Security Package and Cruise Control as a factory option in the US market.

Top reported problems from owners and mechanics

Saddlebag Mounting Failure
The spring wire in the mounting receptacle can lose tension, causing the bag to detach while riding.
Medium
Hydraulic Clutch Master Cylinder
Air can enter the system if the bike is parked for long periods, leading to a 'soft' lever or inability to disengage the clutch.
Low
Engine Heat
The High Output 103 engine runs lean from the factory for emissions, generating significant heat on the rider's right leg in traffic.
