2019 Harley-Davidson FLHRXS Road King Special — Common Issues & Known Problems
Known Issues & Owner Reports
These are the most commonly reported issues and concerns from owners, mechanics, and community forums for the 2019 Harley-Davidson FLHRXS Road King Special.
Oil Sumping
HighOil fails to return to the tank and builds up in the crankcase, causing friction, heat, and power loss. Most prevalent in 2017-2019 M8 engines under heavy load.
Transmission-to-Primary Fluid Migration
MediumTransmission oil migrates into the primary chaincase due to a pressure differential. Can lead to transmission damage if levels drop too low.
Clutch Actuator Leak
HighThe hydraulic clutch secondary actuator can leak fluid internally, leading to a loss of clutch disengagement.
Rear Suspension Bottoming
LowThe 12-inch shocks provide very little travel, leading to a harsh ride over sharp bumps or when riding two-up.
Used Buying Inspection Checklist
What to look for when buying a used 2019 Harley-Davidson FLHRXS Road King Special.
Sumping Check
Run the bike to operating temperature and check for significant power loss or oil carryover in the air cleaner, which indicates oil is pooling in the crankcase.
Fluid Migration
Check the primary fluid level; if it is overfull while the transmission is low, the oil is migrating through the pushrod tunnel.
Clutch Actuator Recall
Verify if Recall 0173 (Secondary Clutch Actuator) has been performed to prevent sudden loss of clutch pressure.
Stretched Bag Scrapes
Inspect the bottom leading edges of the saddlebags for scrapes, as the lowered suspension makes them prone to bottoming out on curbs or steep inclines.
