Gas Gas EC 250 2T [2015-2017]: A Test Ride Through Time with Spain’s Enduro Legend

Introduction

The Gas Gas EC 250 2T isn’t just a motorcycle—it’s a statement. Born in an era when two-stroke enduro bikes were still kings of the dirt, this Spanish machine carved its reputation with a mix of raw power, agile handling, and a personality that’s as fiery as its red-and-black livery. Designed for riders who laugh at the idea of paved roads, the EC 250 2T from 2015 to 2017 remains a compelling choice for hardcore enduro enthusiasts. After spending a day wrestling this beast through rocky trails, muddy ruts, and forest singletrack, here’s why it still deserves your attention (and why you might want to browse our aftermarket catalog afterward).

Engine Performance: Two-Stroke Thunder, Refined

The Heart of the Beast

At its core lies a 249.3cc liquid-cooled two-stroke engine, fed by a Keihin PKW 38mm carburetor. This isn’t the temperamental two-stroke of the 1990s—it’s smoother, with a powerband that’s surprisingly manageable. The engine’s bore and stroke (66.4mm x 72mm) prioritize low-end torque, making it a master of technical climbs. Twist the throttle, and the FMF exhaust barks to life, delivering a linear surge of power that builds into a satisfying mid-range hit. There’s no sudden “light switch” powerband here; instead, the EC 250 2T offers traction-friendly delivery that forgives sloppy throttle hands.

Carburetion & Starting Rituals

The Keihin carburetor performs admirably, though cold starts require patience. The kickstarter is firm but reliable, and the optional electric start (adding 3kg) feels like a luxury on steep hillsides. Purists will appreciate the simplicity—no fuel injection quirks, just a predictable, tunable setup. For riders chasing crisper response, upgrading to a JD Jet Kit (available at MOTOPARTS.store) can fine-tune the fueling for altitude or temperature changes.

Sound & Fury

The FMF exhaust isn’t just for show. It amplifies the engine’s character—a raspy, high-revving snarl that’s music to any two-stroke lover’s ears. Noise levels are reasonable for trail riding, though a spark arrestor might be wise for regulated forests.

Chassis & Handling: Lightweight Precision

Frame & Suspension Setup

The chrome-molybdenum perimeter frame weighs in at just 104kg (229.3 lbs) dry, giving the EC 250 2T a featherweight feel. Paired with Marzocchi’s 45mm Shiver inverted forks (305mm/12 inches of travel) and a Reiger rear shock (298mm/11.7 inches), this bike floats over roots and rocks. The suspension is plush but communicative, with minimal harshness on square-edged hits. For aggressive riders, tweaking the high/low-speed compression on the Reiger shock unlocks even more control.

Steering & Stability

With a 1480mm (58.3-inch) wheelbase and 21-inch front wheel, the EC 250 2T turns like a trials bike. Drop the clutch, and the front wheel tucks into ruts with laser precision. At speed, the chassis remains stable, though the narrow handlebar (32.7 inches wide) might feel twitchy to desert racers. Swapping to a wider aftermarket bar (we recommend ProTaper’s EVO series) adds confidence without sacrificing agility.

Brakes & Wheels

The single 220mm wave discs (front and rear) lack the bite of modern four-piston setups but offer progressive feel. Excel’s aluminum rims are bulletproof—ideal for riders who regularly kiss rocks. The 90/90-21 front and 140/80-18 rear tire combo provides predictable grip, though upgrading to a gummy rear tire (like the Michelin Enduro Medium) transforms loose climbs.

Ergonomics & Comfort: Built for Battle

Rider Triangle

At 950mm (37.4 inches), the seat height is intimidating for shorter riders but perfect for standing attacks. The narrow seat profile lets you grip the bike with your knees, while the pegs are positioned for aggressive weight shifts. After an hour of riding, the firm seat had me longing for MOTOPARTS.store’s gel seat upgrade—a small price for all-day comfort.

Fuel & Range

The 9.5L (2.51-gallon) tank is adequate for 2-3 hours of hard riding. For enduro races or remote trails, consider a larger aftermarket tank. Pro tip: Mixing two-stroke oil at the factory-recommended 1:50 ratio ensures clean combustion and minimal spooge.

Competition: How It Stacks Up

KTM 250 EXC

KTM’s 250 EXC is lighter and packs more adjustability in its WP suspension. However, the Gas Gas counters with a smoother power delivery and a stiffer frame that resists flex in gnarly terrain. The KTM’s Brembo brakes have more initial bite, but the EC 250’s setup feels more forgiving for technical descents.

Husqvarna TE 250

Husky’s TE 250 shares KTM’s DNA but adds a reputation for plush suspension. The Gas Gas fights back with a lower seat height and a more compact feel—ideal for riders under 180cm (5’11”). The Husky’s hydraulic clutch is smoother, but the EC 250’s cable-operated unit is simpler to maintain.

Beta RR 250

Beta’s RR 250 is quieter and emissions-friendly, thanks to oil injection. Yet the Gas Gas feels rawer and more connected, with a chassis that begs to be thrown into corners. Beta wins for trail legality, but the EC 250 dominates in pure adrenaline.

Maintenance: Keeping the Legend Alive

Two-Stroke Simplicity

No cam chains or valve adjustments here! The EC 250 2T’s maintenance revolves around: - Premix Fuel: Stick to 1:50 with premium 2T oil (we recommend Motorex Cross Power 2T). - Air Filter Cleaning: Service after every ride in dusty conditions. Our Twin Air filter kit includes a reusable pre-oiled filter. - Piston Replacements: Every 80-100 hours for aggressive riders. Vertex pistons are a perfect drop-in upgrade.

Suspension & Bearings

Grease the linkage and swingarm bearings annually. The Marzocchi forks benefit from fresh oil every 50 hours—use MOTOPARTS.store’s 5W suspension fluid for optimal damping.

Brakes & Chain

Swap brake pads to sintered units for longer life. The DID 520 chain holds up well, but adding a TM Designworks slider reduces wear on rocky trails.

Final Thoughts

The Gas Gas EC 250 2T isn’t a beginner’s bike. It demands respect, rewards skill, and thrives in the hands of riders who love the mechanical symphony of a two-stroke. While it lacks the gadgets of modern enduros, its simplicity is a virtue—one that’s easily upgraded with aftermarket support. Whether you’re hunting for a new pipe, grippier footpegs, or a softer seat, MOTOPARTS.store has the parts to keep this Spanish legend shredding for years to come.
