2011 Harley-Davidson FLTRU Road Glide Ultra — Maintenance & Ownership Guide
Routine Maintenance
Key maintenance tasks to keep your 2011 Harley-Davidson FLTRU Road Glide Ultra running reliably.
Oil Service
Requires three separate lubricants: 4.0 qts for the engine, 38-45 oz for the primary, and 32 oz for the transmission.
Air Filter
The stock paper element should be inspected every 5,000 miles; many owners upgrade to a washable high-flow filter.
Spark Plugs
Uses Harley-Davidson 6R12 or equivalent (RA8HC) plugs; external rusting is a common cosmetic complaint on this model.
Common Wear Items
Parts that wear over time on the 2011 Harley-Davidson FLTRU Road Glide Ultra and should be inspected regularly.
Compensator Sprocket
The 2011 version is prone to spring fatigue, leading to 'clunking' on startup and metallic rattling at low RPMs.
Brake Pads
Heavy touring weight (874 lbs) leads to relatively fast wear on the front Brembo pads, especially with aggressive ABS usage.
Tires
The rear 180/65B16 Dunlop Multi-Tread is designed for longevity but can develop flat spots if the bike is frequently ridden under-inflated with a heavy passenger.
Popular Upgrades
The most popular aftermarket upgrades for the 2011 Harley-Davidson FLTRU Road Glide Ultra.
Manual Primary Tensioner
Replaces the auto-tensioner to prevent it from over-tightening the chain and destroying the inner primary bearing.
LED Headlights
The stock dual halogen bulbs are often replaced with LED 'Daymaker' style lights for significantly better night visibility.
Aftermarket Compensator
Upgrading to a Baker Drivetrain or the later Screamin' Eagle version solves the 'clunk' and improves drivetrain smoothness.
Common Replacement Parts
Parts that commonly need replacing on the 2011 Harley-Davidson FLTRU Road Glide Ultra.
Inner Primary Bearing
Often fails prematurely due to the automatic primary chain tensioner ratcheting too tight, putting lateral pressure on the bearing.
Voltage Regulator
A frequent failure point for 2011-2012 touring models, often resulting in a 'no charge' condition or 'Check Engine' light.
Used Buying Inspection Checklist
What to look for when buying a used 2011 Harley-Davidson FLTRU Road Glide Ultra.
Primary Noise
Listen for a 'sack of rocks' sound at idle; this indicates a failing compensator or a loose primary chain.
Startup Clunk
A loud bang when the starter engages often points to compensator spring wear or starter ring gear damage.
Oil Cooler Leaks
The 2011 103 engine came with a factory oil cooler; check the adapter and hose fittings for seepage.
Service Records (3 Sumps)
Verify that the primary and transmission fluids were changed at 10k intervals, not just the engine oil.
