RFN Warrior Pro SX-E15: The Gas Killer

Designed from the wheels up as a true motocross/trail bike, the E15 is competitive at the championship level of the 85cc class. Minimal maintenance - spend less time in the garage and more time riding!

Direct Drive Motor - First in Class

Powered by the world’s first direct-drive axial flux motor. By eliminating multi-stage gearing, more energy goes straight to the rear wheel — delivering more power and torque to the tire than competitors rated at the same output or even higher power outputs.

Fully Adjustable Suspension

Fully adjustable rebound and damping let you fine-tune the bike to your speed, terrain, and riding style. Whether you're on a smooth track boosting jumps or a gnarly rock garden, the forks and shock deliver consistent, predictable performance under load, improving corner stability, traction, and control when the pace picks up.

Unmatched Customization

Know exactly how your bike will ride. Five selectable power modes and 10+ fully adjustable in-app settings let you transform the ride from a full-power machine to a smooth, controlled learning platform. A reverse function makes tight maneuvering effortless without unnecessary fatigue, while the safety tether adds an extra layer of protection for both rider and surroundings. The LCD display keeps critical ride data front and center, so you’re always informed and in command.

Race-Worthy Brakes

With safety in mind, the SX-E15 is equipped with high-performance braking components built for steep descents and hard charging into corners. Strong initial bite and consistent stopping power deliver precise control on entry, while balanced modulation allows you to brake later with greater confidence through technical sections and high-speed terrain all while keeping the brakes from overheating.

Quick-Swap Battery

The fun never stops. Easily swap out the battery for a fresh pack in under 90 seconds - the same amount of time it takes to fill up a tank without the hassle and danger of gas.

Precision Control

Industrly leading frame design & throttle control. The frame made of from aerospace-grade aluminum is more responsive under load. With the with advanced real-time control architecture the SX-E15 crafts smoother acceleration, cleaner drive out of corners, and controlled traction in technical terrain and on whoops.

Made To Dominate

Dominant in its class - the RFN Warrior SX-E15 is the next evolution of electric motocross performance.

With it's debut at this years Redbull TKO Enduro Race in Tennessee, this bike has been proven as a champion level bike from the beginning. The rugged course caused other brands electric dirt bikes lose braking power, snap frames, and have broken swing arms, the SX-E15 pushed through with absolutely no issue. Being AMA certified, this bike is ready to race right out of the box!

For years, mid-class motocross bikes have remained unchanged—same frames, same power delivery, same limits. The SX-E15 breaks that mold with cutting-edge electric performance and a design focused on serious racers ready to elevate their skills.

Powered by an advanced 74V system and a true 15,000 Watt Peak Power, the SX-E15 delivers explosive torque, seamless throttle response, and enough power to beat the crap out of 250cc gas bikes. With no clutch, no gears, and no exhaust heat, riders experience pure focus and precision on every lap. Battery swaps take less than 90 seconds, keeping you on the track longer with zero emissions and minimal maintenance. That means no more messy oil changes and no more leaky gas cans.

Every detail—from its lightweight chromoly frame to its fully adjustable race suspension - was fine-tuned to perform at the highest level. Riders can customize every aspect of their setup through the RFN mobile app -adjust top speed, torque, regenerative braking, and power mapping in seconds.

The Warrior SX-E15 isn’t just another bike in the 125cc class - it’s the future of it. Designed to dominate the track, and conquer on trails, the SX-E15 has proven to be the ultimate upgrade.
