Dealer Notes


Forget the high-strung, peaky powerbands of two-strokes past, the TSE300L is the ultimate off-road weapon! 

The liquid-cooled, 300cc powerplant churns out tons of useable power and torque; its incredible low-end-lug will allow you to tiptoe through the gnarliest low-speed terrain a gear or two high. And when it’s time to speed things up, simply roll on the throttle or give the clutch lever a quick stab and the power builds strongly and quickly without being explosive or uncontrollable. 

The integrated balancer shaft almost completely negates vibration at the bars, seat, and footpegs; no more numb hands! 

And we made sure that this powerhouse of a powerplant stays cool no matter what you throw at it! A thermostat mounted directly to the radiator monitors engine temps and kicks the electric cooling fan on or off accordingly. If the engine does start to overheat, an integrated catch tank keeps the coolant from spilling out on the ground, so it can be sucked back into the radiator when things cool down.

The chassis on the TSE300L matches the performance of the engine perfectly, and it is the two-stroke model in the GPX lineup best suited for the rider looking for maximum performance in a wide variety of conditions! 

The rear suspension duties on the TSE300L model are handled by full-adjustable piggyback SZC shock with a linkage. Because of the incorporation of a rear suspension linkage, the TSE300L handles admirably through rough, high-speed sections and whoops. 

The 48mm SZC fork offers the same stock level of performance and adjustability as its European competition. The fork offers adjustable preload, compression, and rebound adjustment, all without needing any tools. 

GPX has also made sure to include the high-end creature comforts on the chassis that the most demanding enduro riders will appreciate, including a hydraulic clutch, tool-less air filter access, a non-slip seat cover, and included skid plate and 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 TSE comes with a competition front number plate included at no extra charge.


    Whether you’re riding first-gear singletrack or open desert, the TSE300 powerplant has plenty of torque and power to match the task! The Balancer Shaft virtually eliminates vibration, which means much less rider fatigue.


    The standard hydraulic clutch allows for an incredibly light, one-finger clutch pull. The hydraulic design also allows for much finer precision and control so you can perfectly modulate the power and traction at the rear wheel.


    Get going immediately with a quick press of the starter button! The electric start motor is integrated into the bottom of the engine to provide a lower center of gravity and to keep it completely out of harms way. And unlike the competition, GPX included a backup kickstarter so an unplanned flat battery won’t ruin your day.


    The linkage rear suspension design has been optimized for precise handling and control through continuous whoops, high-speed G-outs, and faster terrain.
