Sherco 250 SEF [2015 – 2022]: A Test Rider’s Perspective on the Enduro Specialist

Introduction

The Sherco 250 SEF, produced from 2015 to 2022, is a motorcycle that demands respect in the enduro world. Known for its precision engineering and competition-ready DNA, this French-Spanish hybrid (depending on model year) has carved a niche among riders who crave agility, power, and durability in punishing off-road conditions. Over its seven-year production run, the 250 SEF evolved into a machine that balances raw performance with surprising refinement. After a day spent thrashing it through rocky trails, forest singletracks, and open dirt roads, here’s why this bike remains a dark horse in the 250cc enduro segment.

Design & Ergonomics: Built for the Fight

The Sherco 250 SEF’s design screams purpose. Its semi-perimeter chromoly steel frame, finished in minimalist blue/white/green livery (color options vary by year), gives it a lean, aggressive stance. The 950 mm (37.4-inch) seat height might intimidate shorter riders, but the narrow midsection allows boots to grip the bike easily, even when dab-worthy moments arise.

The cockpit is all business: a slim handlebar bend, no-nonsense digital display (on later models), and Michelin Enduro Medium tires mounted on black Excel rims. Sherco’s choice of a 10.4-liter (2.75-gallon) fuel tank strikes a balance between range and weight distribution—critical for technical sections where every kilogram matters. Ground clearance of 355 mm (14 inches) ensures rocky outcrops and fallen logs rarely scrape the underbelly.

Standout detail: the KYB or WP suspension components (varies by model year) are finished in gold anodizing, hinting at the premium tech hiding beneath the plastics.

Engine Performance: Four-Stroke Fury

At the heart of the 250 SEF lies a liquid-cooled, single-cylinder four-stroke engine displacing 248.4–249.3cc. Earlier models (pre-2019) used a carbureted setup, but the shift to Synerject digital fuel injection in later years transformed throttle response. Crack the wrist, and the engine delivers a linear surge of torque starting as low as 3,000 RPM, peaking at a spirited 13,500 RPM.

Key observations from the saddle:
- Low-end grunt: The DOHC valvetrain and 76 x 52.2 mm (3.0 x 2.1-inch) bore/stroke ratio let you tractor up muddy inclines without stalling.
- Mid-range punch: Between 6,000–10,000 RPM, the bike comes alive—ideal for overtaking on fire roads or blitzing through whoops.
- Top-end scream: While not a motocrosser, the 250 SEF rewards aggressive riders with a satisfying howl from its Akrapovic/FMF exhaust (model-dependent).

The hydraulic clutch and 6-speed gearbox are buttery-smooth, though I’d recommend a stiffer clutch spring for heavy abuse. Fuel efficiency hovers around 25–30 km/l (58–70 mpg), meaning you’ll drain the tank in 250–300 km (155–186 miles) of mixed riding.

Handling & Suspension: Dance Partner in the Dirt

Sherco’s chassis geometry—1,480 mm (58.3-inch) wheelbase and 26.5° rake—strikes a perfect balance between stability at speed and flickability in tight woods. The KYB 48mm closed-cartridge forks (or WP units on Factory editions) offer 300 mm (11.8 inches) of travel, while the rear shock serves up 330 mm (13 inches).

Test ride highlights:
- Rocks & roots: The front end absorbs square-edged hits without deflecting, letting you charge through rubble fields.
- Sand washes: Rear suspension stays composed even when the Michelins claw for traction.
- Rutted corners: Flicking the 102 kg (224.9 lb) dry-weight bike between lines feels instinctive.

Brembo brakes deliver stoppies on demand, though the 220 mm (8.7-inch) discs can fade during prolonged downhill descents—a perfect excuse to upgrade to MOTOPARTS.store’s sintered pads.

Competition: How It Stacks Up

The 250cc enduro class is fiercely contested. Here’s how the Sherco fights its corner:

1. KTM 250 EXC-F:
2. KTM’s flagship is lighter (98 kg/216 lb) and packs more peak horsepower.

3. Sherco’s edge: Superior low-end torque and plush suspension for technical terrain.

4. Husqvarna TE 250i:

5. Husky’s TPI injection gives crisper throttle response.

6. Sherco’s edge: More durable chromoly frame and easier maintenance access.

7. Beta RR 250:

8. Beta’s softer power delivery suits beginners.
9. Sherco’s edge: Race-bred KYB/WP suspension outclasses Beta’s Sachs units.

While the Austrian brands dominate sales, the Sherco 250 SEF appeals to riders valuing mechanical simplicity and chassis feedback over outright speed.

Maintenance: Keeping the Beast Alive

The 250 SEF is built to endure, but smart upkeep ensures longevity:

1. Air Filter:
2. Clean every 15 hours (or after every dusty ride).

3. Upgrade tip: MOTOPARTS.store’s twin-air foam filters improve airflow and filtration.

4. Oil Changes:

5. Replace engine oil every 20 hours; use 10W-50 full synthetic.

6. Don’t forget the hydraulic clutch fluid (DOT 4).

7. Suspension Service:

8. Rebuild forks/shock every 100 hours. Consider MOTOPARTS.store’s SKF seal kits for smoother action.

9. Chain & Sprockets:

10. O-ring chains last longer, but stick with DID for OEM reliability.

11. Cooling System:

12. Flush coolant annually. A 60:40 water-to-coolant mix prevents overheating in slow technical sections.

Final Verdict

The Sherco 250 SEF isn’t just a bike—it’s a statement. It caters to riders who value precision over popularity, offering a blend of torquey four-stroke power, unflappable suspension, and race-grade components. While it demands respect (and occasional wrenching), few bikes in its class deliver such a visceral connection to the trail. Whether you’re chasing hard enduro podiums or weekend singletrack glory, this Sherco deserves a spot in your garage—and MOTOPARTS.store has the upgrades to make it truly yours.
