500 EXC-F (MY2017)

4.5 / 5 NastyNils Rating · against its class

The Light-Footed Big Single

The Machine's Character

The 500 EXC-F is a big-bore four-stroke enduro bike, and the headline isn't the 64 hp or the 33 lb-ft. It's how little motorcycle wraps around that 511 cc single. You get a steel double-cradle frame, a 21-inch front and an 18-inch rear. Suspension is adjustable at both ends, with 11.8 in (300 mm) of travel up front and 12.2 in (310 mm) out back. On the trail it feels light, and that saves you energy in every tight section. The electronics stay lean, and traction control is available as an option. It's a tool for riding hard. Pure orange!

It's built tough, and the aftermarket support is deep, so you can shape it around your terrain and the way you ride. As the hours pile up it asks for the care any hard-used enduro bike needs: fork seals can leak after heavy mud, and the plastics crack from impacts, the rear fender and side panels especially. Some units also start hard or drain the battery. It's for experienced off-road riders who want a big single for technical ground and open desert, and who'd rather spend the day on rocks than on pavement. Check those points when you buy. Then go ride.

The Voice of Experience

Portrait of NastyNils

The test ride

Swing a leg over and the first thing you notice is the height: a 37.8 in (960 mm) seat and 14.0 in (355 mm) of ground clearance put you way up there. Once you're standing on the pegs, that height turns into room to move. Thumb the starter and the 511 cc single settles into a deep, round thump that sounds just right for a big four-stroke in the woods. At real trail pace the bike talks to you through your boots and your hands, and there's almost no distance between you and the ground. That's KTM. What stuck with me came later. Usually a quicker bike wears you down and the fun fades by afternoon. Here it went the other way: the faster it got, the more I enjoyed it. That's rare!

Rated point by point — where it earns its keep

My own 0–100 score for this bike against the class, area by area — the marker on each bar is the class average.

The part that impressed me is that the gains didn't pull in a single direction. Progress usually lands as either a stopwatch bike or an easy one to ride, and this took both. It's genuinely quicker, it carries less, and it's more rewarding under you at the same time. I spent a whole day rotating across everything the range covers, fast and open through to tight and awkward, and the pace never read like it had been bought at the expense of enjoyment.

The trait I trust most here is how little effort the bike demands when the trail knots up. It's dropped mass, and you register that in every direction change, so a technical section leaves you with something in the tank rather than drenched and cooked. The steering got keener too, and normally that costs you composure through ruts and rock. This time it didn't. Reworking the fork, frame, and rear as one package let the quick response and the planted feel arrive together.

Let me set expectations: a single day with the press won't tell you how this holds up over years, and I won't pretend otherwise. It isn't nothing, though. Every bike in the fleet was ridden hard, back to back, from early light until the sessions ended, and each one was still going at the finish. On a machine rebuilt almost top to bottom, that clean run across the whole group says the groundwork was done properly before any of them shipped.

Output climbed everywhere, but that improvement barely registered next to how the engine now carries itself at low revs. The pickup is honest, the drive builds instead of spiking, and I could trust it on a steep line without fighting a sudden hit. The clever piece is the injection reading which gear you've selected and tailoring fuel to it, so a slow technical section and a fast one ask for very different inputs, and the bike sorts that out for you.

On a machine this focused, comfort is really a question of body position, and the new saddle opens that up. I could work further back over the tail on steep descents than the old one let me, and the perch itself is kinder on the longer transfers. What I won't sugarcoat is the firmness out of the crate. The factory calibration is built around riders far faster than most of us, so I'd back the damping off front and rear before a serious session rather than after.

The Truth on the Trail

None of these miles are mine. Instead I've spent years listening to the people who own this thing: trailhead chatter, the observations riders pass around, and the messages that reach me from folks flogging one hard. The split is clear. Long, steady praise for the dirt, and a short list of familiar gripes.

The engine leads the praise

The engine tops most accounts. Owners describe grunt that arrives barely off idle, a strong middle, and enough up high to clear climbs. For a thumper this size they call the delivery smooth and predictable, easy to meter even for riders still building skill. The chassis earns the same trust: light, quick to change line, and as composed in tight singletrack as on grass or a technical climb. A few say it's simple to wrench on.

The short list of gripes

Two complaints sit up front. Owners flag lean stock fueling and emissions gear that runs rough until they reflash and free it up. Another group fights random no-starts and dim lights, usually traced to the battery or wiring. Lower down, some watch fork seals seep after muddy rides, and almost nobody calls it comfortable on the highway, where the vibes and missing wind protection wear on you.

Known issues

  • Rough running due to lean emissions mapping

    fuel system common

    Stock ECU mapping and restrictive exhaust/intake cause hesitation, stalling, and flame-outs. Desmogging and an ECU reflash/tuner are common fixes.

  • Clutch slippage under load

    drivetrain occasional

    Riders report clutch slippage during hard acceleration, often due to worn clutch plates. Replacement of the clutch pack typically resolves the issue.

  • Intermittent starting issues / battery drain

    electrics occasional

    Some units experience hard starting or a dead battery, often linked to parasitic draw or weak factory batteries.

  • Fork seal leakage

    suspension occasional

    Fork seals can develop leaks after riding in heavy mud. Regular cleaning and occasional replacement may be required.

  • Suspension harshness if not properly set

    suspension occasional

    Some owners find the stock suspension feels stiff or under-damped for their weight/terrain; re-springing and re-valving can resolve.

  • Cracked plastics

    bodywork occasional

    Plastics and body panels are prone to cracking from impacts or rough handling, especially the rear fender and side panels. Regular inspection and reinforcement with aftermarket parts can mitigate the issue.

The 'Should I Buy It?' Score

Forget spec-sheet bragging. Here's who the 500 EXC-F is actually built for.

Best motorcycle for Moab?

You're the best fit for this bike. Ledges, sand and technical climbs are exactly where the light steering, 14.0 in (355 mm) of clearance and long travel pay off.

Best motocross bike for Loretta Lynns?

It'll run laps at your local MX track, but it's an enduro bike at heart, set up for roots and rocks more than jump faces. A good match, not a perfect one.

Made for Loretta Lynn's Ranch · Carnegie State Vehicular Recreation Area · Pala Raceway

Best motorcycle for BDR routes?

A partial fit. On the technical stretches it's brilliant, but with a 2.2 gal (8.5 L) tank and no luggage system, multi-day BDR logistics are yours to solve.
