Full-On Enduro, Street-Legal
The FE 501 is a competition enduro that happens to carry a plate. Its 511 cc liquid-cooled single makes 44 hp and 32 lb-ft, and the way it hands that torque over matters far more than the peak figure. A hydro-formed chromium-molybdenum frame, WP XACT suspension with 11.8 in (300 mm) of travel at both ends, and 13.5 in (343 mm) of ground clearance put it at the serious end of the class. Traction control is standard, both ends are adjustable, and the rest of the bike is stripped of anything that does not help you get through terrain.
It rewards a rider who reads traction instead of chasing revs. Drive builds cleanly enough to lug through slow rock, and it still has the legs for open desert, while the chassis stays honest as the hours pile up. This is a machine for experienced off-road riders who already know what they want from one. The caveats are real: 37.8 in (961 mm) of seat height rules out short inseams, the 2.2 gal (8.5 L) tank keeps your range short, there is no ABS, and it wants proper scheduled maintenance rather than occasional attention.

Chassis
First thing you notice is the perch. At 37.8 in (961 mm) you sit on top of this bike rather than in it, and at a stop with one boot hunting for ground it feels every bit that tall. Moving, that disappears. It is narrow between your knees, the bars land where they should the moment you stand up, and it changes line with a shift of your hips instead of a shove. The single has a hard, dry bark that carries across open ground, and there is a steady pulse through the pegs at trail speed that never turns into buzz. The levers are light, the seat is a plank on anything resembling pavement, and hard-packed chatter arrives muted rather than sharp. You finish a long day tired in your legs, not your hands.
I did not assemble this from a single day in the saddle. It comes out of conversations that stack up over years: parking lot talk at the trailhead, questions at club evenings, and the notes owners send once a season has gone by. With the FE 501, the same handful of observations keeps surfacing.
Two things dominate the praise. Riders talk about power they can meter out, thick and usable from just off idle, strong when they lean on it and calm when they don't. The chassis draws the same broad agreement: it turns quickly, holds its line through tight sections, and stays composed when the ground opens up. Fewer voices, though steady ones, mention a cockpit that keeps them comfortable deep into a long day, and values that stay high a couple of seasons on.
Starting sits at the top of the complaints. Owners describe a bike that resists firing, an idle that will not settle, and a habit of dying while sitting in gear, most often once everything is hot. Damping comes next, and opinions split. Some call the stock setup too stiff over small stuff, others say it goes vague at pace. Riders in both camps report that a proper setup or a re-valve sorts it.
Front brake caliper may crack (safety recall)
Irregularities in the casting structure of some BRAKTEC front brake calipers can lead to cracking at the upper guide pin, reducing braking effectiveness. A recall has been issued to inspect and replace affected calipers.
Fuel pump and filter early failure
The in‑tank fuel pump and filter can degrade prematurely, leading to lean running and stalling. Replacement is often recommended at around 200‑300 hours of use.
Engine stalling and difficult hot starting
The engine can be reluctant to fire when hot and may stall unexpectedly when pulling the clutch at idle. Often linked to a weak battery, idle settings, or fuel mapping.
Suspension setup suboptimal from factory
Several riders report that the stock WP XACT suspension does not suit their weight or riding style and requires re‑springing or valving changes for optimal performance.
Intermittent electrical starting issues
Some owners experience intermittent no‑start conditions due to weak battery, corroded wiring, or faulty electrical connections.
Countershaft seal leak
A few owners report oil seeping from the countershaft seal, potentially worsening with high mileage.
Transmission shifting difficulties
Some riders report difficulty shifting gears, often linked to clutch adjustment or slipping, causing grinding or resistance.

Forget spec-sheet bragging. Here's who the FE 501 is actually built for.
This is the tool for exactly that riding. Clearance, travel, and low-speed drive all point at slickrock and sand, and it stays light enough that a technical section is still fun late in the day.
Made for Bar M / Kane Creek · Imperial Sand Dunes · Johnson Valley OHV Area
It will run closed-course laps happily. Understand what you are buying, though: an enduro tuned for traction and drive, carrying lights and a plate, not a stripped machine built purely for the gate.
Made for Carnegie State Vehicular Recreation Area · Fox Raceway at Pala · Glen Helen Raceway
Right bike for the roughest sections, wrong bike for the miles between them. The 2.2 gal (8.5 L) tank and race-pace service intervals make multi-day logistics your main planning problem.
Made for AZBDR — Arizona Backcountry Discovery Route · California BDR South · COBDR — Colorado Backcountry Discovery Route
If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.
Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Husqvarna FE 501. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
