Gas Gas EC 250 2T (2006-2007): A Forgotten Gem in the Enduro Arena

Introduction

The Gas Gas EC 250 2T from 2006-2007 is a motorcycle that demands respect from riders who understand the raw appeal of two-stroke enduro machines. While the Spanish brand has always lived in the shadow of Austrian giants like KTM, this particular generation proves why Gas Gas earned its cult following. Designed as a no-compromise off-road weapon, the EC 250 2T combines explosive power with surprisingly refined chassis dynamics. After spending a day wrestling this bike through rocky trails, muddy ruts, and open fire roads, it’s clear this machine was built by riders, for riders. Let’s dissect what makes this underdog worth rediscovering.

Engine Performance: Two-Stroke Fury, Modern Control

At the heart of the EC 250 2T lies a liquid-cooled 249cc single-cylinder engine that epitomizes the golden era of two-stroke enduro bikes. The 66.4 mm bore and 72 mm stroke (2.6 x 2.8 inches) create a powerband that’s more tractable than the “light switch” reputation of older 250cc two-strokes. With 49.8 hp @ 8,699 rpm and 45.4 Nm (33.5 lb-ft) of torque @ 7,628 rpm, this engine doesn’t just scream—it communicates.

The 38mm Keihin PWK carburetor deserves praise. Unlike finicky Mikuni setups of competitors, this carb delivers crisp throttle response across elevations. You’ll notice a deliberate lean toward mid-range punch rather than all-out top-end frenzy. In technical climbs, the EC 250 pulls like a tractor from as low as 4,000 rpm, yet still rewards aggressive riders with a violent rush past 7,000 rpm. The hydraulic clutch (a luxury in this era) offers buttery modulation, essential when balancing clutch slips during gnarly ascents.

What’s unexpected is the engine’s manners. The Kokusan digital ignition tames the hit, making it less intimidating for intermediate riders. You won’t need to constantly dance on the gearbox—the 6-speed transmission ratios are spaced to keep the engine in its sweet spot. Sixth gear becomes a relaxed cruiser at 80 km/h (50 mph), though true two-stroke aficionados will prefer staying in the meaty midrange.

Handling: Precision Meets Durability

Gas Gas’s Deltabox frame—constructed from Cr-Mo steel tubing with an aluminum swingarm—strikes a balance between flex and rigidity that modern bikes often over-engineer. At 102 kg (225 lbs) dry, the EC 250 feels shockingly light when flicked into corners. The 1,476 mm (58.1-inch) wheelbase provides stability at speed without sacrificing agility in tight singletrack.

The suspension package shames many 2023 models. Up front, 45mm Marzocchi upside-down forks soak up square-edged hits with 295 mm (11.6 inches) of travel. Out back, the Öhlins shock (310 mm/12.2 inches travel) delivers progressive damping that’s plush on small chatter yet firm enough for big landings. Unlike some linkage systems, Gas Gas’s straight-rate setup stays predictable when you’re deep into a moto whoop section.

Standout features include: - Braking: The 260mm front dual-disc setup (a rarity in 2006) offers stoppie-on-demand power, while the 220mm rear disc allows precise speed modulation. - Ergonomics: The 945 mm (37.2-inch) seat height feels towering but pairs with narrow bodywork for easy leg reach. You’ll appreciate the 340 mm (13.4-inch) ground clearance when straddling fallen logs. - Tires: The 90/90-21 front and 140/80-18 rear combo provides a perfect balance of slide control and bite in loose terrain.

Competition: How It Stacks Up

The 2006-2007 enduro market was dominated by: 1. KTM 250 EXC: More peak power (52 hp) but a harsher powerband. KTM’s WP suspension was stiffer, favoring expert riders. 2. Husqvarna WR250: Comparable weight but with dated ZF suspension. The Husky’s V-force reeds couldn’t match Gas Gas’s low-end grunt. 3. Yamaha WR250F: Four-stroke rival with smoother delivery but 10+ kg heavier. Maintenance costs were higher.

The EC 250’s advantage lay in its balanced package. It lacked KTM’s top-end scream but offered better low-RPM manners. While Japanese bikes prioritized reliability over performance, Gas Gas delivered race-ready components (Öhlins, Marzocchi) at a time when rivals used budget parts. The Achilles’ heel? Brand recognition. Gas Gas struggled in dealer networks, making aftermarket support crucial—a gap MOTOPARTS.store now fills comprehensively.

Maintenance: Keeping the Beast Alive

Two-strokes live and die by their maintenance rituals. The EC 250 2T is refreshingly simple compared to modern fuel-injected four-strokes, but demands attention in three key areas:

1. Top-End Rebuilds: Expect to replace pistons every 40-50 hours of hard riding. Always check ring gap and cylinder scoring.
2. Carb Tuning: The Keihin PWK thrives on cleanliness. Clean the pilot jet monthly if riding in dusty conditions. Consider upgrading to a JD Jet Kit for altitude compensation.
3. Suspension Service: Marzocchi forks require 15W oil changes every 30 hours. The Öhlins shock benefits from a nitrogen recharge annually.

Pro Tips from MOTOPARTS.store: - Swap stock reeds with Boyesen RAD valves for better throttle response. - Protect the expansion chamber with a Moose Racing guard. - Upgrade brake pads to sintered compounds for improved bite in wet conditions.

Conclusion: A Timeless Off-Road Tool

The Gas Gas EC 250 2T (2006-2007) isn’t just a relic—it’s a reminder of when enduro bikes prioritized function over form. While it lacks the TPI systems and mapping controllers of modern machines, its simplicity is its strength. For riders who enjoy tinkering as much as riding, this generation offers a perfect canvas for customization. Whether you’re reviving a barn find or upgrading a well-loved example, MOTOPARTS.store stands ready to keep this Spanish legend tearing up trails for another decade.
