“Middle half” is the range the middle 50% of listings fall in, so one cheap gasket or one show-chrome set does not skew it. Counted from listings that are the part itself, not hardware for it, and recalculated from the live catalog every time the site is built.
Fine to buy used
- Cosmetic and bolt-on trim — covers, fenders, mirrors, bars, seats. What you see is what you get.
- Hard parts for bikes no longer supported — sometimes the only source for a 50-year-old casting.
- Complete assemblies from a known low-mileage bike — a stock exhaust or wheel pulled at a dealer upgrade is often nearly new.
Think twice before buying used
- Brakes — pads, rotors, lines, master cylinders. You cannot see internal corrosion or wear.
- Tires and tubes — rubber ages even when unused. Check the date code.
- Batteries — an unknown charge history is an unknown lifespan.
- Fuel lines, seals, gaskets — cheap new, expensive when a used one leaks.
- Steering-head and wheel bearings — wear does not show until it is in the bike.
Checking a used part fits
The same rule applies new or used: match the model code and the year. Look up the part’s Harley-Davidson number in our OEM lookup — the fitment on the matching aftermarket listing tells you which bikes that part was made for. Our fitment guide covers the common traps.
And buying used from strangers online: read our scam warnings first.
