Rider Profile

Best ForBest suited to riders who already have some experience handling heavy, big-displacement cruisers at low speed.
PurposeBuilt primarily for relaxed long-distance highway touring and boulevard cruising rather than outright speed or sport riding.
Rider FitThe substantial dry weight of around 328 kg and low seat height make it manageable at rest but demanding to muscle around in tight maneuvers or parking situations.
CharacterA classic big-twin American tourer with a torque-rich V2 engine, deep exhaust note, and stately, unhurried road manners.
Not Ideal ForNot a good fit for riders seeking sharp cornering agility, off-road capability, or quick acceleration.

2004 Harley-Davidson FLHRI Road King Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 693mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 Harley-Davidson FLHRI Road King, with a cramped knee angle of around 75 degrees and an upright riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.

⚠ Safety Recalls (1)

FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY Sep 2004 · 04V465000

ON CERTAIN MOTORCYCLES, A CONDITION OCCURS THAT COULD ALLOW PRESSURE TO BUILD UP IN THE FUEL TANK. ON FUEL INJECTED VEHICLES, THIS CONDITION COULD CAUSE FUEL TO SPRAY OUT UNEXPECTEDLY WHEN THE FUEL CAP IS REMOVED. ON CARBURETED VEHICLES, EXCESSIVE FUEL COULD BE TRANSFERRED TO THE CARBURETOR, WHICH WOULD EVENTUALLY ALLOW FUEL TO DRIP FROM THE AIR CLEANER.

Risk: THESE SITUATIONS COULD CAUSE SERIOUS PERSONAL INJURY OR CREATE A FIRE HAZARD FOR PERSONS OR PROPERTY ON OR NEAR THE MOTORCYCLE.

Remedy: DEALERS WILL TEST EACH CANISTER FOR BLOCKAGE, THEN REPLACE AS NECESSARY. THE RECALL BEGAN NOVEMBER 4, 2004. OWNERS SHOULD CONTACT HARLEY-DAVIDSON AT 1-414-343-4056.
