Here is a look at how the 2025 KTM 300 EXC compares to the 2025 Rieju MR 300 Racing based on their technical specifications.
Who Each Bike Suits
The KTM 300 EXC suits riders who want modern throttle-body fuel injection and the simplicity of a PDS no-linkage rear suspension system. As the reference two-stroke enduro bike, it offers 293.2 cc of displacement and a 6-speed gearbox.
The Rieju MR 300 Racing suits riders who prefer a traditional carburetor and linkage-based rear suspension. This Spanish-built two-stroke offers a slightly larger 299.3 cc displacement and features both an electric and kick starter for backup.
Key Differences

- Rear Suspension: The KTM features a WP XPLOR shock using a PDS (no linkage) design with 310 mm of travel. The Rieju uses a KYB shock with a linkage setup.
- Front Suspension: The KTM is equipped with a WP XACT 48 mm fork, whereas the Rieju uses a KYB 48 mm closed-cartridge fork. Both offer 300 mm of front suspension travel.
- Starting: The KTM relies solely on an electric starter. The Rieju provides both an electric starter and a kick starter.
- Weight: The KTM is listed at 104.6 kg (without fuel), and the Rieju is 105 kg (dry). Because these are measured differently, the weights are not directly comparable.

If you prefer fuel injection and the log-clearing advantages of a PDS rear shock, the KTM 300 EXC is the better choice. If you prefer the familiar tuning of a carburetor, KYB suspension with a linkage rear, and a backup kick starter, the Rieju MR 300 Racing is the one to get.
