Gas Gas EC 250 2T (2008-2010): A Time-Tested Enduro Warrior Still Demanding Respect

Introduction

The Gas Gas EC 250 2T is a motorcycle that refuses to fade into obscurity. Produced between 2008 and 2010, this Spanish two-stroke enduro machine carved its name into the dirt of hardcore off-road enthusiasts’ hearts. With its razor-sharp handling, aggressive power delivery, and race-bred DNA, the EC 250 remains a compelling choice for riders who crave authenticity in an era increasingly dominated by four-strokes and electronics. After spending time with this machine on tight single-track trails, rocky ascents, and open fire roads, it’s clear why it still commands loyalty—and why certain upgrades from MOTOPARTS.store could elevate its already formidable capabilities.

Design & Build Quality: Function Over Flair, But Built to Last

Frame & Ergonomics

The EC 250’s Deltabox frame—crafted from chromium-molybdenum steel tubing—is a masterclass in minimalist durability. Paired with an aluminum swingarm, the chassis strikes a balance between rigidity and flex, absorbing impacts without feeling vague. At 1,476 mm (58.1 inches) wheelbase, the bike feels planted at speed but remains flickable in technical terrain.

Standing at 945 mm (37.2 inches), the seat height is typical for enduro bikes of this era, though taller riders might appreciate lowering links or a shaved seat (both available at MOTOPARTS.store). The narrow midsection allows easy leg grip, and the overall dry weight of 102 kg (225 lbs) makes it feel like an extension of your body rather than a burden.

Suspension Setup

• Front: The 45mm Marzocchi upside-down forks offer 295 mm (11.6 inches) of travel. While not as adjustable as modern counterparts, they handle roots and rocks with a plushness that surprises, only getting overwhelmed in extreme G-out scenarios.
• Rear: The Öhlins shock (310 mm / 12.2 inches of travel) is the star here. Its progressive linkage keeps the rear planted during acceleration and compliant over square-edged hits.

Brakes & Wheels

• Front Brake: A 260mm disc with a single-piston caliper delivers adequate stopping power, though riders used to newer bikes might crave more bite. Upgrading to sintered pads or a braided steel line (available in our store) sharpens response.
• Rear Brake: The 220mm disc does its job without drama, ideal for modulating slides on loose surfaces.
• Tires: The 90/90-21 front and 120/80-18 rear combo provides predictable grip, though many riders swap to modern rubber like Michelin Enduro Mediums for enhanced performance.

Engine Performance: Two-Stroke Thunder in a Refined Package

Power Delivery

The 249cc liquid-cooled two-stroke engine is a study in controlled aggression. With 49.8 hp @ 8,699 rpm and 45.4 Nm (33.5 lb-ft) of torque @ 7,628 rpm, it’s not the most powerful in its class, but its powerband is exceptionally usable. The 38mm Keihin PWK carburetor ensures crisp throttle response, though jetting can be finicky in extreme temperatures—a JD Jet Kit from MOTOPARTS.store solves this.

• Low-End: Torque builds linearly from idle, allowing clutch-free crawling over logs.
• Mid-Range: A strong surge kicks in around 5,000 rpm, perfect for lofting the front wheel or powering out of berms.
• Top-End: The engine signs off early compared to MX-focused two-strokes, but this suits enduro riding where sustained revs are rare.

Transmission & Clutch

The 6-speed gearbox ratios are spaced for versatility:
- 1st-3rd: Tight for technical climbs
- 4th-6th: Long enough for connecting trails or short highway stints
The hydraulic clutch (a rarity in this era) offers buttery lever action and consistent engagement, even after hours of abuse.

On the Trail: Where the EC 250 Shines

Technical Terrain

In slow, rocky sections, the EC 250 feels telepathic. The combination of light weight and precise steering lets you pivot around obstacles with minimal effort. The suspension soaks up embedded rocks without deflecting, and the torquey engine pulls cleanly from near-stall RPMs.

High-Speed Sections

At speed, the bike remains stable despite its short wheelbase. The Öhlins shock keeps the rear wheel tracking true over whoops, though the front fork could use stiffer springs for aggressive desert racing.

Hill Climbs

Here, the two-stroke’s instant power pays dividends. The EC 250 claws up steep, loose inclines with minimal clutch fanning, though a larger rear sprocket (+2 teeth) improves leverage for extreme climbs.

Competition: How It Stacks Up Against Rivals

KTM 250 EXC (2008-2010)

• Strengths: More aggressive powerband, lighter feel, broader dealer network.
• Weaknesses: Stiffer suspension setup less forgiving on trail trash, higher maintenance costs.
• EC 250 Edge: Superior rear suspension action and a smoother power delivery for technical riding.

Husqvarna WR 250 (2008-2010)

• Strengths: Italian-made reliability, six-speed gearbox, strong aftermarket.
• Weaknesses: Heavier at 108 kg (238 lbs), less responsive chassis.
• EC 250 Edge: Livelier engine character and better ergonomics for stand-up riding.

Yamaha WR 250F (4-Stroke)

• Strengths: Broader torque spread, quieter for trail compliance.
• Weaknesses: Heavier (116 kg / 256 lbs), less explosive fun factor.
• EC 250 Edge: Unmatched power-to-weight ratio and easier maintenance.

Maintenance: Keeping the EC 250 in Fighting Shape

Key Service Points

1. Premix Ratio: The 2.5% oil mixture (40:1) is critical. Use high-quality synthetic oils like Motul 800 Off-Road to prevent seizures.
2. Air Filter: Clean every 10-15 hours. Upgrade to a Twin Air filter with grease-sealed edges for dusty conditions.
3. Piston Replacement: Every 80-100 hours for aggressive riders. Wiseco forged pistons improve longevity.
4. Suspension Rebuild: Service forks every 50 hours and shock every 100. MOTOPARTS.store offers SKF seal kits for smoother action.

Common Upgrades

• Carburetor: Swap to a Lectron or SmartCarb for altitude-immune fueling.
• Exhaust: An FMF Fatty pipe boosts mid-range punch.
• Brakes: Galfer wave rotors (stock on Six-Days models) reduce mud buildup and improve bite.

Wear Items to Stockpile

• Drive chains (DID 520ERV3)
• Sprockets (Supersprox Stealth)
• Brake pads (EBC MXS Series)

Conclusion: A Legacy Worth Preserving (and Upgrading)

The Gas Gas EC 250 2T isn’t a beginner’s bike, nor is it a showpiece. It’s a raw, responsive tool for riders who value mechanical simplicity and direct feedback. While newer bikes offer more refinement, few match its visceral connection to the trail. With strategic upgrades—many available right here at MOTOPARTS.store—this generation can still embarrass modern machinery in the hands of a skilled rider. Whether you’re resurrecting a barn find or optimizing a well-loved example, the EC 250 rewards those willing to embrace its two-stroke soul.
