2021 FE 501 - Pros & Cons
Strengths
-
⚡
Strong power output: 2021 Husqvarna FE 501 makes 45 hp with Nm @ rpm of torque - competitive figures for its class.
Considerations
-
🔧
Carburetor fuelling: Carbureted engines need occasional jetting attention and can be reluctant in cold weather or at altitude compared to modern fuel-injected alternatives.
-
📏
Tall seat height: The 950 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
Owner Experiences & Common Issues
Carburetor maintenance
Carburetors on the 2021 Husqvarna FE 501 benefit from a clean and re-jet if the bike has been stored, run on stale fuel, or modified with an aftermarket exhaust. Owners frequently mention that fresh jets and float needle clips transforms throttle response from flat to crisp.
Valve clearance checks
Single Overhead Cams (SOHC) engines should have valve clearances checked at the manufacturer's specified interval. Owners report that clearances can tighten over time on higher-mileage bikes, leading to slight ticking from the top end. Catching it early keeps the job simple and avoids more costly remediation.
FE 501 - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2021 Husqvarna FE 501, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained FE 501 should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task on any FE 501. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
Carburetor upkeep
Keep the carburetors clean and free of deposits. If the FE 501 has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
Valve clearance service
Check that valve clearances have been adjusted at the correct intervals on any used FE 501. This is a job many owners skip because the bike does not immediately feel wrong - but tight clearances accelerate valve seat wear. Ask for proof it has been done.
