Comparing the 2025 GasGas EC 300 and the 2025 Sherco 300 SEF Factory (sometimes mistakenly called the Sherco SEF 300) comes down to a fundamental choice: two-stroke versus four-stroke. Both are purpose-built European enduro motorcycles, but they take different approaches to the trail.
Who Each Bike Suits
The GasGas EC 300 suits riders who want the snap and agility of a two-stroke. With its 293.2 cc engine and throttle-body fuel injection, it offers traditional two-stroke traits with modern fuel management for technical trails.
The Sherco 300 SEF Factory appeals to riders who prefer the traction and predictable power delivery of a four-stroke. The 303.7 cc French-built machine bridges the gap between 250 and 450 four-strokes.
Key Differences
The most significant difference is the engine type. The GasGas is a 293.2 cc two-stroke, while the Sherco is a 303.7 cc four-stroke. Neither manufacturer publishes horsepower figures, so they are best compared by engine type and displacement. On the trail, the two-stroke GasGas will feel snappier, while the four-stroke Sherco provides steadier traction.
Suspension components differ completely. GasGas uses WP XPLOR 48 mm open-cartridge forks with 300 mm of travel and a WP XACT shock with linkage offering 300 mm of travel. Sherco runs KYB 48 mm closed-cartridge forks with 300 mm of travel and a KYB rear shock that provides 330 mm of travel.
Seat height is important for shorter riders: the GasGas sits slightly taller at 956 mm compared to Sherco's 950 mm. Both bikes feature a 6-speed gearbox, fuel injection, and an electric starter.
The GasGas weighs 107.6 kg without fuel. Sherco's weight is not published in a verified source, so they cannot be directly compared on the scale. For range, the Sherco holds slightly more fuel at 9.8 L versus the 9 L capacity of the GasGas.
Pricing also separates the two. The GasGas has a 2025 US list price of $10,799 before freight, while the Sherco lists for $12,499.
Which Should You Buy?
Choosing between these two models primarily depends on your engine preference. If you want a two-stroke with modern throttle-body injection and a lower purchase price, the GasGas EC 300 is the clear option. If you prefer the power delivery of a mid-sized four-stroke and KYB suspension, the Sherco 300 SEF Factory is the bike for you.
