Gas Gas EC 250 2T (1997-2001): A Forgotten Gem of Enduro Racing

Introduction

The Gas Gas EC 250 2T is one of those motorcycles that never quite achieved household-name status but left an indelible mark on hardcore enduro enthusiasts. Produced between 1997 and 2001, this Spanish two-stroke enduro bike carved out a niche with its razor-sharp handling, lightweight design, and a powerband that could shame bigger-displacement machines. Riding this bike today feels like unearthing a time capsule of late-’90s off-road innovation—a machine that prioritizes raw, unfiltered riding engagement over modern gadgetry. Let’s dive into what makes this bike special and why it still deserves attention from riders who value mechanical purity.

Engine and Performance: Two-Stroke Thunder

At the heart of the EC 250 2T lies a 249cc liquid-cooled single-cylinder engine, producing 49.8 hp at 8,699 rpm and 45.4 Nm (33.5 lb-ft) of torque. These numbers might seem modest by today’s standards, but on the trail, they translate to explosive acceleration and a power delivery that’s both thrilling and demanding.

The 38mm Keihin PWK carburetor ensures crisp throttle response, while the Kokusan digital CDI ignition system provides reliable spark even in wet conditions. What stands out most, though, is the engine’s character. Unlike modern fuel-injected bikes, the EC 250 requires finesse—you’ll need to work the clutch and manage the revs to keep it in its sweet spot. The hydraulic clutch (a premium feature for its time) helps here, offering smooth modulation during technical climbs or sudden throttle cuts.

The six-speed transmission is a highlight. Gear shifts are precise, and the ratios are perfectly spaced for everything from crawling over rocks to flat-out trail blasts. On open fire roads, you’ll hit 110-115 km/h (68-71 mph) comfortably, though the engine’s raucous exhaust note and lack of vibration damping remind you this is a purpose-built dirt machine.

Chassis and Handling: Lightweight Precision

With a dry weight of 102 kg (225 lbs), the EC 250 feels almost telepathic in its handling. The chromoly Deltabox frame and aluminum swingarm strike a balance between rigidity and flex, allowing the bike to track predictably over uneven terrain. At 1,476 mm (58.1 in), the wheelbase is short enough for quick direction changes but stable enough at speed.

Throw it into a tight singletrack, and the EC 250 carves through corners with minimal input. The 21-inch front and 18-inch rear wheels (shod with period-appropriate knobby tires) provide ample grip, though modern rubber would undoubtedly unlock even more potential. Ground clearance of 340 mm (13.4 in) means you’ll rarely drag the chassis over logs or rocks, and the 37.2-inch seat height accommodates taller riders without feeling overly intimidating.

Suspension and Brakes: ’90s Premium Components

Gas Gas didn’t cut corners with the EC 250’s suspension. The 45mm Marzocchi upside-down fork offers 295 mm (11.6 in) of travel, tuned for a plush initial stroke that soaks up small bumps while firming up under heavy compression. Out back, the Öhlins shock (with 310 mm/12.2 in of travel) delivers progressive damping, keeping the rear wheel planted during hard acceleration.

Braking duties are handled by a single 260mm front disc and 220mm rear disc, both with single-piston calipers. While adequate for the bike’s weight, the brakes lack the bite of modern systems. You’ll need to plan stops earlier, especially when descending steep hills. Upgrading to sintered pads (available at MOTOPARTS.store) is a worthwhile investment for aggressive riders.

Ergonomics and Comfort: Function Over Luxury

The EC 250’s cockpit is minimalist but effective. The seat is thin and firm—a trait common to race-oriented bikes—but the riding position is natural, with wide handlebars and mid-set footpegs encouraging an active stance. Standing up for technical sections feels intuitive, thanks to the bike’s narrow profile and centralized mass.

Fuel capacity is 9.5 liters (2.5 gallons), which translates to a range of roughly 80-100 km (50-62 miles) depending on riding style. Carry extra fuel if you’re planning a long backcountry loop. Vibrations are noticeable at high RPMs, but that’s part of the two-stroke charm—this isn’t a bike for lazy cruising.

Competition: How It Stacks Up

In the late ’90s, the EC 250 faced fierce rivals like the KTM 250 EXC, Husqvarna WR250, and Yamaha WR250. Here’s how it compares:

• KTM 250 EXC: The Austrian bike had a slight edge in power delivery, with a broader torque curve. However, the Gas Gas countered with superior suspension (Öhlins vs WP) and a lighter feel in technical terrain.
• Husqvarna WR250: Known for bulletproof reliability, the Husky was heavier and less agile. The EC 250’s hydraulic clutch and six-speed gearbox also gave it a usability advantage.
• Yamaha WR250: Yamaha’s four-stroke offered smoother power but couldn’t match the Gas Gas’s explosive acceleration or flickable handling.

Where the EC 250 truly shone was in its niche as a “racer’s bike.” It demanded skill but rewarded it with unmatched agility and a visceral connection to the trail.

Maintenance: Keeping the Legend Alive

Owning a Gas Gas EC 250 2T today requires dedication, but the payoff is a uniquely raw riding experience. Here are key maintenance considerations:

1. Two-Stroke Oil Mix: The 2.5% premix ratio (25ml of oil per liter of fuel) is critical. Use high-quality synthetic oil to prevent piston seizures.
2. Air Filter Care: Clean the foam filter after every ride. Consider upgrading to a twin-air filter for better airflow and debris protection.
3. Cooling System: Check coolant levels regularly. These engines run hot, and a failed water pump seal can lead to catastrophic overheating.
4. Suspension Service: Rebuild the Marzocchi forks and Öhlins shock annually. Fresh oil and seals will restore their plush feel.
5. Brake Upgrades: Swap stock brake pads for EBC sintered units (available at MOTOPARTS.store) to improve stopping power.

Conclusion: A Timeless Off-Road Weapon

The Gas Gas EC 250 2T isn’t just a relic—it’s a reminder of how exhilarating motorcycling can be when stripped down to its essentials. Its combination of lightweight agility, explosive power, and premium components makes it a joy to ride even decades later. While modern enduro bikes offer more refinement, few can match the EC 250’s raw character. For riders willing to embrace its quirks, this Spanish legend remains a worthy companion on the trails. And when it’s time to replace those worn-out parts? You know where to look.
