2026 GPX FSE300R

The FSE300R might be the best bike in the GPX four-stroke lineup! Why? It’s the perfect combination of four-stroke torque with the light and playful feeling of a small-bore.

The main feature of this impressive bike is its 298cc liquid-cooled DOHC powerplant. The Twin-Cam design allows for faster revs and more power. The FSE300R can be ridden hard and revved like a 250F, but the extra displacement that adds up to 300 supplies additional power and torque that delivers low-end grunt and tractability.

Electronic Fuel injection makes sure that the engine runs great in hot or cold temperatures, down at sea-level or high up in the mountains, all while delivering excellent fuel economy. 

It doesn’t matter if you’re tackling tight terrain or blasting through the open desert, the engine temps stay in check thanks to a thermostat-controlled electric cooling fan that kicks on and off automatically, and a coolant overflow tank.

The central backbone frame is made of chromo steel for the perfect combination of strength and flex to provide precise handling, and the alloy subframe reduces the weight compared to a traditional steel unit. 

48mm SZC fork offers adjustable compression, and rebound adjustment, all without needing any tools. The rear suspension duties are handled by full-adjustable piggyback SZC shock with a linkage. This all adds up to a chassis with confidence-inspiring stability that is ready for any obstacle in its path!

GPX has also made sure to include the high-end creature comforts on the chassis that the most demanding enduro riders will appreciate, including tool-less air filter access, a non-slip seat cover, a skid plate, and a front disc guard.

And GPX included as stock equipment all the little goodies that often go unmentioned but are hard to live without! 

• Handguards keep your fingers and protected from brush, roost, and inclement weather. 
• Front fork adjustments are easy to make without tools or getting off the bike, and the built-in speed-bleed buttons make it a snap to release built up air pressure in the forks. 
• CNC-machined billet aluminum components cover the entire bike, including the hubs, bar clamps, and triple clamp. 
• Speaking of the triple clamp, we’ve included tie-down rings on the bottom triple clamp to make it super easy to tie your bike down in your truck or trailer without scratching the 1-1/8” bars.
• A super bright LED headlight makes it easy to find your way home for those times that your adventures go on after dark. 
• Going racing? Every full-size FSE comes with a competition front number plate included at no extra charge.
