2010 Harley-Davidson FLHX Street Glide — Maintenance & Ownership Guide
Routine Maintenance
Key maintenance tasks to keep your 2010 Harley-Davidson FLHX Street Glide running reliably.
Brake Fluid Flush
Critical 2-year interval for ABS models to prevent HCU failure due to moisture/deposits.
Primary Chaincase Lubricant
Requires 38-45 oz of fluid; check for metal shavings on the magnetic drain plug at every oil change.
Drive Belt Tension
Check every 5,000 miles; improper tension leads to premature pulley wear or snapped belts.
Common Wear Items
Parts that wear over time on the 2010 Harley-Davidson FLHX Street Glide and should be inspected regularly.
Rear Tire (Dunlop D407)
Heavy touring use leads to 'cupping' or flat-spotting if pressures are not maintained at 40-42 PSI.
Compensator Sprocket
The stock 2010 compensator is prone to 'clunking' on startup and eventual failure; often replaced with the SE (Screamin' Eagle) version.
Brake Pads
Brembo pads provide high stopping power but wear faster on heavy touring chassis; check thickness every 5,000 miles.
Popular Upgrades
The most popular aftermarket upgrades for the 2010 Harley-Davidson FLHX Street Glide.
Stage 1 Air/Fuel/Exhaust
Solves the lean/hot running condition caused by the factory catalytic converter in the headpipe.
Rear Suspension
The stock 12-inch air shocks have limited travel; upgrading to 13-inch coil-overs (Ohlins/Legend) significantly improves ride quality.
Common Replacement Parts
Parts that commonly need replacing on the 2010 Harley-Davidson FLHX Street Glide.
Battery (66010-97)
High-compression V-Twin requires a strong cold-cranking amp (CCA) rating; typical lifespan is 3-4 years.
Voltage Regulator
Known failure point on this era of touring bikes, leading to charging system failure.
Used Buying Inspection Checklist
What to look for when buying a used 2010 Harley-Davidson FLHX Street Glide.
ABS Service Records
Verify fluid was flushed every 2 years; lack of service can lead to a $1,000+ ABS module replacement.
Exhaust Heat Shields
Check for bluing or rattling, which can indicate the catalytic converter is running excessively hot or the mounts are cracked.
Inner Primary Bearing
Listen for a whirring noise in neutral that disappears when the clutch is pulled; common failure on high-mileage Twin Cams.
