2020 Harley-Davidson Ultra Limited — Maintenance & Ownership Guide
Routine Maintenance
Key maintenance tasks to keep your 2020 Harley-Davidson Ultra Limited running reliably.
Oil Change (3-Hole)
Requires three separate fluids: engine oil (~4.5-5 qts), primary chaincase lubricant (~1 qt), and transmission lubricant (~1 qt).
Coolant Level
Twin-Cooled models require periodic checks of the coolant reservoir located in the right-side lower fairing.
Common Wear Items
Parts that wear over time on the 2020 Harley-Davidson Ultra Limited and should be inspected regularly.
Rear Tire
The high torque of the 114 engine and the 900+ lb weight of the bike lead to rapid rear tire wear, often needing replacement every 8,000-12,000 miles.
Brake Pads
The heavy touring chassis puts significant load on the Brembo pads, especially the rear, which can wear faster than expected if the linked braking system is used heavily.
Popular Upgrades
The most popular aftermarket upgrades for the 2020 Harley-Davidson Ultra Limited.
Stage 1 Performance
Commonly includes slip-on mufflers, high-flow air cleaner, and a tuner to improve exhaust note and throttle response.
Tour-Pak Quick Disconnect
Allows owners to remove the heavy King Tour-Pak for a 'Street Glide' look and improved low-speed handling when touring capacity isn't needed.
Handlebars (Ape Hangers)
Many riders find the stock bars too low; 10-14 inch bars are common to improve ergonomics for taller riders.
Used Buying Inspection Checklist
What to look for when buying a used 2020 Harley-Davidson Ultra Limited.
Coolant Pump and Hoses
Check for white residue or leaks around the water pump (bottom of frame) and the hoses leading into the lower fairings.
Primary Fluid Level
Check for 'fluid transfer' where transmission oil migrates into the primary; though mostly resolved by 2020 with a factory vent, it is still worth verifying on high-mileage bikes.
Infotainment Boot-up
Ensure the Boom! Box GTS system boots quickly and the touchscreen is responsive; software glitches were common and often require firmware updates.
