Comparing the 2025 KTM 300 EXC and the Sherco 300 SEF Factory means looking at two very different engine types built for enduro riding.
Who Each Bike Suits
The KTM 300 EXC is a 293.2 cc two-stroke motorcycle. It is designed for riders who prefer the specific power delivery of a two-stroke engine. In the United States, this exact model name is not sold, but the equivalent bike is available as the 300 XC-W.
The Sherco 300 SEF Factory is a French-built 303.7 cc four-stroke motorcycle. It sits between Sherco's 250 and 450 four-stroke models and suits riders who want a mid-displacement four-stroke engine instead of a two-stroke.
Key Differences
- Engine Type: The KTM is a two-stroke, while the Sherco is a four-stroke. Neither manufacturer publishes horsepower figures.
- Rear Suspension: The KTM uses a WP XPLOR shock with a PDS system, meaning it has no linkage, providing 310 mm of travel. The Sherco uses a KYB shock with a linkage system, offering 330 mm of travel.
- Seat Height: The KTM has a taller seat height at 963 mm, compared to the Sherco at 950 mm.
- Fuel Tank: The Sherco holds slightly more fuel with a 9.8 L tank, while the KTM has a 9 L tank.
- Weight: The KTM weighs 104.6 kg without fuel. Sherco does not publish a verified weight for the 300 SEF Factory, so a direct weight comparison cannot be made.
- Price: The KTM 300 XC-W (the US equivalent) lists at $11,599, while the Sherco 300 SEF Factory lists at $12,499 before freight.
- Both bikes share a 6-speed gearbox, electric starters, fuel injection (the KTM specifically uses throttle-body fuel injection), and 300 mm of front suspension travel, though the KTM uses a WP XACT 48 mm fork and the Sherco uses a KYB 48 mm closed-cartridge fork.
Which Should You Buy?
Choosing between these two models primarily comes down to whether you want a two-stroke or a four-stroke engine. If you want a two-stroke engine and prefer a PDS rear suspension without a linkage to catch on logs, the KTM 300 EXC is the choice. If you prefer the characteristics of a four-stroke engine, a lower seat height, and linkage rear suspension, the Sherco 300 SEF Factory fits those criteria.
