Gas Gas EC 300 2T (1999–2020): A Timeless Enduro Legend

Introduction

The Gas Gas EC 300 2T isn’t just a motorcycle—it’s a statement. For over two decades, this Spanish-built enduro machine has carved its name into the dirt of every trail, forest, and rocky hillside it’s tackled. From its debut in 1999 to its final iterations in 2020, the EC 300 remained a favorite among riders who crave raw two-stroke power paired with precision handling. Climbing onto the bike, the first thing you notice is its purposeful stance: a slim profile, aggressive seat height (940 mm / 37 inches), and a chassis that whispers, “Let’s get dirty.” Whether you’re a seasoned enduro racer or a weekend warrior, the EC 300 demands respect—and rewards it with adrenaline.

This review dives into what makes the EC 300 a enduring icon, from its snarling engine to its race-bred suspension. We’ll also explore how it stacks up against rivals and share key maintenance tips to keep it tearing through trails for years to come.

Engine Performance: Two-Stroke Thunder

Power Delivery That Thrills

At the heart of the EC 300 lies a liquid-cooled 294cc two-stroke engine, producing 50 hp at 7,340 rpm and a stump-pulling 49 Nm (36.3 lb-ft) of torque at 6,890 rpm. The magic here is in its versatility. Crack the throttle open, and the bike surges forward with a linear powerband that’s more tractor than light switch—a rarity in high-strung two-strokes. The Keihin PWK 38mm carburetor (a constant across all model years) delivers crisp throttle response, while the adjustable power valve lets riders tweak the hit from mellow to manic.

Low-End Grunt: Where the EC 300 shines is in technical terrain. The engine lugs down to near-idle RPMs without stalling, making it a cheat code for hill climbs and rock gardens. First-gear crawls feel effortless, and the hydraulic clutch (a premium touch) ensures fatigue-free modulation.

Mid-to-Top Scream: Once the power valve opens, the bike transforms. The exhaust note sharpens, and the front wheel lifts with minimal effort. While it’s no MX weapon, the EC 300’s six-speed gearbox lets it stretch its legs on open trails, hitting speeds north of 130 km/h (81 mph) with ease.

Reliability & Fueling

The simplicity of the two-stroke design means fewer mechanical headaches. Mixing fuel at a 2% oil ratio (50:1) is non-negotiable, but the engine tolerates a range of premix oils. Riders in colder climates might tweak the carb jetting, but stock settings work surprisingly well for most conditions. Later models (2017+) added electric start—a welcome upgrade for trailside convenience.

Handling & Suspension: Precision Meets Plushness

Chassis: Agile Yet Stable

The EC 300’s chromoly steel frame (Deltabox design) strikes a perfect balance between rigidity and flex. With a 1476 mm (58.1 in) wheelbase and 103 kg (227 lbs) dry weight, the bike flicks through switchbacks like a trials machine but remains planted at speed. Standing up on the pegs, the bike feels narrow—a design choice that pays dividends in tight woods.

Suspension Setup

• Front: Earlier models (1999–2008) used 45mm Marzocchi upside-down forks with 295 mm (11.6 in) of travel. Post-2010, Sachs and KYB forks entered the mix, offering adjustable compression/rebound for finer tuning. The 2017 model’s Marzocchi Shiver 48mm forks were a standout, absorbing rocks and roots without deflection.
• Rear: The Öhlins shock (standard on most years) provides progressive damping, with 310 mm (12.2 in) of travel. Later editions like the Nambotin Replica swapped in a TTX Öhlins unit for pro-level adjustability.

On the Trail: The EC 300’s suspension soaks up small bumps like a sponge but firms up predictably under hard hits. It’s plush enough for all-day rides yet responsive when you’re pushing pace.

Ergonomics & Braking

Rider Triangle

The EC 300’s cockpit is minimalist but functional. The seat is firm but narrow, making it easy to shift weight forward on steep descents. At 940 mm (37 in), the seat height is intimidating for shorter riders, but the bike’s low center of gravity inspires confidence once moving.

Stopping Power

• Front Brake: A 260mm disc with a single-piston caliper (Nissin on later models) offers strong initial bite. Upgraded Galfer wave rotors on special editions (e.g., Six-Days) reduced mud buildup.
• Rear Brake: The 220mm disc lacks progression but pairs well with the engine’s compression braking for controlled slides.

Competition: How the EC 300 Stacks Up

The EC 300’s rivals read like a who’s-who of enduro royalty:

1. KTM 300 EXC

2. The Austrian benchmark. KTM’s 300 is lighter (105 kg vs. 103 kg) and has a broader dealer network. However, the Gas Gas counters with a plusher stock suspension and a torquier low-end.

3. Husqvarna TE 300

4. Shares KTM’s DNA but with a smoother power delivery. The Husky’s composite subframe feels more modern, but the EC 300’s steel frame is tougher in crashes.

5. Beta 300 RR

6. Beta’s smooth powerband suits technical trails, but the EC 300’s hydraulic clutch and Öhlins suspension give it a premium edge.

Verdict: The EC 300 isn’t the fastest or lightest, but its blend of torque, suspension plushness, and durability makes it a dark horse for riders who value rideability over spec sheets.

Maintenance: Keeping the Legend Alive

Key Upkeep Tips

1. Premix Faithfully: Stick to a 2% oil ratio (50:1) with quality synthetic oil. A failing oil pump (on e-start models) can spell disaster.
2. Air Filter Care: Clean the foam filter after every ride. Consider a Twin Air aftermarket filter for improved airflow.
3. Suspension Service: Rebuild forks/shocks annually. Upgrade to SKF seals for longer life.
4. Brake Upgrades: Swap stock pads for sintered units (e.g., EBC MXS) for better bite in wet conditions.

MOTOPARTS.store Recommendations

• Exhaust: Boost mid-range with an FMF Gnarly pipe.
• Grips: Cushion vibrations with ProGrip 714 dual-density grips.
• Chain Kit: DID VT2 X-Ring chain for longevity in muddy conditions.

Conclusion
