GasGas EC 300: a 300 cm³ two-stroke enduro motorcycle and what to check when buying used
GasGas EC 300 — a 300 cm³ two-stroke enduro motorcycle, known for being lightweight, powerful, and robust. We look at the generations, technical specs, and what to check when buying used.
EC 300 in brief
EC — the badge for the GasGas enduro series, with the EC 300 being the largest two-stroke in the lineup. This is a motorcycle for extreme enduro, rocky, and forest trails: lightweight with good low-end torque, making it suitable for technical hill sections.
GasGas — a brand from Catalonia (Spain). In later years, it changed owners, and since 2019, it has belonged to the Pierer Mobility group (alongside KTM and Husqvarna). As a result, older EC 300s and newer models differ in technology and heritage.
Generations — what sets them apart
Older, Spanish-made EC 300s often feature simpler technology: carburettor-fed two-stroke engines, basic electronics, and plenty of mechanical parts that can be maintained independently. These motorcycles are valued for their simplicity but may be quite worn.
Newer EC 300s post-2020, built on the group’s platform — with a newer frame, suspension, and more modern equipment. Before buying, check if the specific motorcycle is carburettor-fed or fuel-injected, as this affects maintenance and quirks.
Engine and gearbox
300 cm³ two-stroke engine, liquid-cooled, with a gearbox and hydraulic clutch. Two-strokes are light and responsive, but they demand more attention: you need to mix or supply oil correctly, regularly change the piston and rings.
Electric start or kickstart depends on the year and version — check for the specific motorcycle.
What to check when buying a used EC 300
Ask when the piston, rings, and connecting rod bearings were last changed. Start the two-stroke cold: it shouldn’t smoke excessively, misfire, or run unevenly at idle.
Inspect the exhaust system (bends, leaks), suspension, wheel bearings, chain, sprockets, and brakes. This is race-derived tech, so you often find damaged plastics, bent radiators, and other signs of crashes.
Check the frame for cracks and deformations, documents, and whether the motorcycle hasn’t been disguised as another make or year. Many of these types of motorcycles in Lithuania aren’t registered for road use.
Versions
Names and equipment vary by market and year; we list generally described versions, but check the exact specification in the documents of the specific motorcycle.

Frequently asked questions
What sets the EC 300 apart from the EC 250?
Single-cylinder enduro motorcycles. 300 cm³ offers more low-end power and tackles steep climbs more easily, while 250 cm³ is more lively and easier to handle.
Is a two-stroke suitable for a beginner?
It is, if the motorcycle is easy to handle and the rider wants to learn. However, two-strokes respond abruptly, so powerful models require experience.
What does EC mean?
EC is the badge for the GasGas enduro series. It differs from MC (motocross) and road models with ES or SM badging.
