KTM 250 EXC-F (2012–2016) Review: The Lightweight Enduro Powerhouse

Introduction

The KTM 250 EXC-F isn’t just a motorcycle—it’s a statement. From 2012 to 2016, this Austrian enduro machine dominated trails, races, and riders’ hearts with its blend of agility, power, and race-ready engineering. Designed for riders who demand precision in the gnarliest terrain, the 250 EXC-F carved its legacy as a podium regular in enduro competitions. But how does it hold up for the everyday rider or weekend warrior? Let’s dive into what makes this bike a standout, even years after its production run.

Engine Performance: A Firecracker in the Dirt

At the heart of the KTM 250 EXC-F lies a 248.6 cc liquid-cooled, single-cylinder DOHC engine. This isn’t your average thumper—it’s a high-revving, titanium-valved powerhouse that spins up to a screaming 13,000 RPM. The Keihin electronic fuel injection (EFI) system delivers crisp throttle response, whether you’re crawling over rocks or pinning it through open fire roads.

Key Highlights:
- Broad Powerband: Torque starts low (thanks to a 76 mm bore and short 54.8 mm stroke) and pulls relentlessly to the top. Riders will appreciate the lack of “dead zones”—the power builds linearly, making it manageable for technical sections yet explosive when you crack the throttle.
- EFI Tuning: The Keihin EMS allows automatic altitude and temperature adjustments, a game-changer for riders tackling mountain trails or desert heat. Optional map-select switches (sold separately) let you toggle between aggressive and smoother power curves.
- Electric + Kick Start: The combo starter system ensures reliability. Cold mornings? The electric starter (a rarity in 250cc enduros of this era) is a blessing.

The engine’s 13.2:1 compression ratio demands premium fuel, but rewards you with 38 PS (28 kW) of raw power. For reference, that’s comparable to modern 250cc MX bikes, but tuned for enduro’s grueling demands.

Handling: Where Precision Meets Playfulness

KTM’s chromoly steel frame and WP suspension setup make the 250 EXC-F feel like an extension of your body. At 107.5 kg (237 lbs) dry, it’s remarkably light—nearly 10 kg (22 lbs) lighter than a Yamaha WR250F of the same era.

Chassis & Suspension:
- WP USD 48mm Forks: The open-cartridge forks offer 300 mm (11.8 in) of travel, absorbing everything from sharp roots to high-speed G-outs. Adjustability is straightforward: compression and rebound damping clicks are easy to tweak for rider weight or terrain.
- WP PDS Rear Shock: The Progressive Damping System (PDS) eliminates linkage, reducing weight and complexity. With 335 mm (13.2 in) of rear travel, it’s plush on landings yet firm enough to avoid bottoming out.
- Agile Geometry: A 63.5° steering head angle and 1,482 mm (58.4 in) wheelbase strike a balance between quick steering and stability. Throw it into a rutted corner, and the front end digs in with laser focus.

The CNC-machined hubs and Excel rims (21” front, 18” rear) wrapped in Maxxis FIM-spec tires provide exceptional grip. You’ll notice the lack of rotational mass—the bike flicks sideways with minimal effort, a trait adored in tight singletrack.

Ergonomics: Built for Battle

KTM’s “Ready to Race” ethos shines in the 250 EXC-F’s cockpit. The seat height—970 mm (38.2 in)—is tall but narrow, letting shorter riders dab a foot without sacrificing comfort. Standing up? The tapered aluminum handlebar and slim fuel tank (9.5L / 2.5 gal) offer unrestricted movement.

Rider Triangle:
- Seat: Firm foam prioritizes control over cushioning, but aftermarket options can soften long rides.
- Controls: Hydraulic clutch pull is featherlight, and the Neken handlebar bends reduce arm pump.
- Bodywork: Revised in 2012, the plastics and airbox design repel mud and simplify filter swaps (no tools needed!).

Ground clearance of 345 mm (13.6 in) means rocks and logs rarely touch the frame. Just watch the exhaust silencer—it sits low and can scrape in deep ruts.

Competition: How Does It Stack Up?

The 250 EXC-F’s rivals in the enduro 250cc class include:

1. Yamaha WR250F

• Pros: Softer suspension for beginners, legendary reliability.
• Cons: Heavier (117 kg / 258 lbs), carbureted until 2015.
• KTM Edge: Lighter weight, EFI, and sharper handling.

2. Husqvarna TE250 (Pre-Husky/KTM Merger)

• Pros: Similar performance, distinctive styling.
• Cons: Older models lacked KTM’s WP suspension refinement.
• KTM Edge: More aftermarket support and dealer network.

3. Honda CRF250X

• Pros: Smooth power delivery, electric start (2017+).
• Cons: Outdated air-cooled engine in early 2010s, heavier chassis.
• KTM Edge: Higher-tech engine, superior suspension.

The 250 EXC-F’s closest match is its Austrian cousin, the Husqvarna TE250. However, KTM’s PDS rear suspension and slimmer profile give it a slight edge in technical terrain.

Maintenance: Keeping the Orange Beast Alive

Owners praise the 250 EXC-F’s durability, but neglect is its kryptonite. Here’s how to keep it thriving:

1. Valve Adjustments

• Intake: 0.10–0.15 mm (0.004–0.006 in)
• Exhaust: 0.12–0.17 mm (0.005–0.007 in)
  Check every 40 hours. Use a feeler gauge from MOTOPARTS.store for precision.

2. Oil Changes

• Capacity: 1.2L (with filter). Use SAE 10W-50 synthetic.
• Interval: Every 15 hours. Swap filters every other change.

3. Air Filter Care

Clean after every ride. Upgrade to a twin-air filter for better airflow and dust protection.

4. Chain & Sprockets

The 13/50T sprocket combo wears quickly in mud. Replace with a DID ERT2 chain and steel sprockets for longevity.

5. Cooling System

Flush coolant annually. Use ethylene glycol-based fluid and check for leaks at the water pump (a known weak spot).

6. Brakes

DOT 4 fluid absorbs moisture—bleed annually. Upgrade pads to sintered metal for aggressive riding.
