Readers may know these bikes by older or mistaken names like the GasGas EC 200 or the Rieju MRT 300, but this page covers the current model names: the 2025 GasGas EC 250 and the 2025 Rieju MR 300 Racing. Both are 2-stroke enduro motorcycles with 6-speed gearboxes and rear suspension linkage.
Who Each Bike Suits
The GasGas EC 250 suits riders looking for a smaller displacement 2-stroke with a lighter-revving engine. It features modern throttle-body fuel injection and an open-cartridge WP fork.
The Rieju MR 300 Racing suits riders who prefer a larger displacement 2-stroke engine and traditional fueling. It comes with a carburetor, a closed-cartridge KYB fork, and the added peace of mind of a backup kickstarter.
Key Differences
- Engine Size and Fueling: The GasGas has a 249 cc engine utilizing throttle-body fuel injection. The Spanish-built Rieju has a 299.3 cc engine fed by a carburetor. Neither manufacturer publishes horsepower figures for these models.
- Suspension: Both bikes offer 300 mm of front travel and rear shocks with linkage. However, the GasGas uses a WP XPLOR 48 mm open-cartridge fork and a WP XACT shock, while the Rieju uses a KYB 48 mm closed-cartridge fork and a KYB shock.
- Starting: The GasGas relies solely on an electric starter. The Rieju features both electric and kick starting.
- Weight: The GasGas weighs 107.6 kg (without fuel). The Rieju weighs 105 kg (dry). Because these weights are measured using different methods, they are not directly comparable.
- Fuel Capacity: The Rieju has a slightly larger tank at 9.8 L, compared to the 9 L tank on the GasGas.
- Pricing and Extras: The GasGas EC 250 has a 2025 US list price of $10,499 (before freight), a 956 mm seat height, and 354 mm of ground clearance. The Rieju is sold in the US, but the 2025 US list price is not confirmed.
Which Should You Buy?
If you want the precision of modern fuel injection and a slightly smaller, lighter-revving 249 cc engine, the GasGas EC 250 is the choice. If you prefer a larger 299.3 cc engine, a traditional carburetor, closed-cartridge forks, and the inclusion of a kickstarter, the Rieju MR 300 Racing is the better option.
