Used Buying Inspection Checklist

What to look for when buying a used 2016 Harley-Davidson FLHR Road King.

Primary/Transmission Leaks

Check the bottom of the cases for oil 'weeping,' which can indicate a failing inner primary seal or shifter shaft seal.

Cold Start Lifter Noise

Listen for a sharp metallic ticking that doesn't go away after 30 seconds; this can indicate worn lifters or cam chain tensioner issues.

Charging System Voltage

Stator failures are common; verify the battery shows 13.5V-14.5V while the engine is running.

Saddlebag Latch Operation

Ensure the one-touch latches click firmly; if misaligned, they can pop open at highway speeds.
