2019 Harley-Davidson FLTRXS Road Glide Special — Maintenance & Ownership Guide
Routine Maintenance
Key maintenance tasks to keep your 2019 Harley-Davidson FLTRXS Road Glide Special running reliably.
Fluid Changes
Requires three separate fluids: engine oil (approx 4.5-5 qt), primary lubricant (approx 1 qt), and transmission lubricant (approx 1 qt). 1,000-mile break-in service is critical.
Brake Fluid Flush
Harley-Davidson specifies a DOT 4 fluid flush every 2 years regardless of mileage to prevent moisture-related ABS module failure.
Common Wear Items
Parts that wear over time on the 2019 Harley-Davidson FLTRXS Road Glide Special and should be inspected regularly.
Rear Tire
The high torque of the 114 engine and the 800+ lb weight often results in rear tire life between 8,000 and 12,000 miles.
Brake Pads
Heavy touring use wears front pads faster; Brembo-branded pads are standard and provide strong bite but create significant dust.
Popular Upgrades
The most popular aftermarket upgrades for the 2019 Harley-Davidson FLTRXS Road Glide Special.
Windshield
The stock 'Special' windshield is very low and purely cosmetic; most owners upgrade to a taller 'spoiler' style for better wind protection.
Stage 2 Cam Kit
Commonly installed to unlock the 114 engine's potential, improving mid-range passing power and adding a traditional Harley 'lope' to the idle.
Rear Suspension
The stock hand-adjustable shocks have limited travel (approx 2 inches); many owners upgrade to aftermarket shocks (e.g., Ohlins, Legend) for better ride quality.
Used Buying Inspection Checklist
What to look for when buying a used 2019 Harley-Davidson FLTRXS Road Glide Special.
Transmission Fluid Level
Check for 'fluid transfer' where transmission oil migrates into the primary case. A low transmission dipstick with a high primary level indicates this issue.
Boom! Box GTS Functionality
Verify the touchscreen is responsive and check for screen flickering or 'ghost touches' which can occur in high heat.
Primary Vent Installation
Look for a small vent tube installed on the primary inner cover; this was the factory fix for the oil transfer issue.
