2010 Harley-Davidson FLHR Road King
About the 2010 Harley-Davidson FLHR Road King
The 2010 FLHR Road King is a classic touring motorcycle featuring the air-cooled Twin Cam 96 engine and the refined touring chassis introduced in 2009. This model year is notable for the introduction of a helical-cut 5th gear for quieter operation and a factory-installed catalytic converter in the 2-1-2 exhaust. It serves as the 'standard' Road King, distinguished by its hard-shell saddlebags and cast aluminum wheels compared to the leather-wrapped 'Classic' (FLHRC) trim.
What Makes This Trim Special
- Hard Saddlebags — Injection-molded GTX® hard bags with one-touch latches, color-matched to the bike. (Street Glide, Electra Glide)
- 28-Spoke Cast Aluminum Wheels — 17-inch front and 16-inch rear black cast wheels with machined highlights.
- Hiawatha Headlight — Large 7-inch chrome nacelle headlight with auxiliary passing lamps.
- Detachable Windshield — Large clear Lexan windshield that can be removed without tools in seconds.
Likely but unverified:
- Cruise Control — Optional on the FLHR Standard for 2010, whereas it was standard on the FLHRC Classic.

Frequently Asked Questions About the 2010 Harley-Davidson FLHR Road King
Yes, it uses Harley-Davidson's Electronic Sequential Port Fuel Injection (ESPFI) as standard equipment.
ABS was an optional factory feature for the 2010 FLHR. You can identify it by the sensor wires running to the wheel hubs and the ABS light on the console.
The Standard (FLHR) has hard saddlebags and cast wheels. The Classic (FLHRC) has leather-wrapped bags, spoked wheels with whitewall tires, and standard cruise control.
The engine oil capacity is approximately 4.0 quarts (3.8L) with a filter change, though you should start with 3.5 quarts and check the dipstick.
This is usually the compensator sprocket bottoming out. It is a common trait of the 2010 model year and often requires an upgrade to the Screamin' Eagle compensator.
Yes, 2010 was the first year all Harley Touring models had a catalytic converter located in the header pipe collector (near the rider's right foot).
Actually, 2010 was the year Harley fixed the whine by switching to a helical-cut 5th gear. Models from 2007-2009 had straight-cut 5th gears that were much noisier.
The rear suspension is air-adjustable. There is a Schrader valve located behind the left saddlebag. Use a manual low-pressure pump (not an air compressor) to adjust between 0-50 PSI.
