Introducing the **2026 ETM™ RTR Sport**, the newly engineered, newly strengthened, and newly powered evolution of the original ETM RTR. Designed in California and battle-tested by riders who demand real performance, the RTR Sport is built to send harder, last longer, and stay cooler; no matter how aggressive the terrain gets. This isn’t a refresh. This is a **fundamentally improved machine** from the inside out. #### What’s New on the 2026 RTR Sport ##### All-New Revolver Motor, More Torque, More Pull, More Everything The RTR Sport debuts our **Revolver Motor**, delivering a huge leap in torque output, sustained power delivery, and responsiveness. With stronger magnets, improved rotor structure, and increased thermal efficiency, the Revolver is built for riders who don’t roll off; they roll on. ##### 420 Chain & Sprockets: Built for Real Moto Abuse Goodbye bicycle chain. The RTR Sport upgrades to a full **420-grade moto chain and sprocket system**, offering dramatically increased strength, smoother power transfer, and long-term durability under hard acceleration and jumps. ##### Reinforced Peg Bar: Stronger, Stiffer, Ride-Hard Approved We rebuilt the peg bar from the ground up with a **thicker, stronger, more rigid design**. Whether you’re standing deep in whoops or sending tabletops, the peg bar stays planted and confidence-inspiring. ##### Reinforced Swingarm: More Stability, More Predictability The rear end now features a **heavily reinforced swingarm** to handle higher loads, harder hits, and more powerful drivetrains. The result: improved tracking, better corner stability, and a more connected feel between rider and rear wheel. ##### Improved Braking System: More Bite, Better Modulation Upgraded Master Cylinder, refined fluid dynamics, and improved rotor feel make the RTR Sport stop harder and more consistently. Whether you’re trail riding or downhill braking into a tight berm, the system is tuned for smooth modulation and serious stopping power. ##### Upgraded Battery Management: Deeper Discharge, Longer Range, More Power When It Counts The RTR Sport features a **newly optimized battery management system** engineered for deeper discharge levels, allowing riders to tap into **more of the pack’s usable energy**. The result is **significantly extended real-world range** and the ability to maintain **higher power output for longer sessions** without the performance drop-off typical of smaller trail bikes. More miles, more throttle, more laps — all from the same compact hot-swap platform. ##### Improved Thermal Management: Rip Longer Without Heat Soak An all-new thermal strategy across the motor, controller area, and battery compartment results in **dramatically improved temperature stability**. Hard riding sessions stay consistent instead of dropping off due to heat. **Note:** This product is not fully waterproof (only water resistant) and some assembly is required. **Specifications:** **Frame:** - E&C Designed Tubular Steel Frame - Removable Subframe - Extra rigid swingarm with CNC MX style axle blocks **Product Weight:** - 130 Lbs - 48% Front , 52% Rear **Wheelbase:** - 1130mm (44.5 Inch) **Seat:** - Full Length Foam Padded with Quick Release - Seat Height - 760mm (30 Inch) **Tires:** - MX 60/100-14; 80/100-12 **Power:** - 8,000 Watts Max Output - Three Selectable Power Levels **Speed:** - 55+mph Max Speed **Motor:** - E&C Revolver IPM brushless motor **Suspension:** - 48mm E&C Tuned Dual Adjustable Forks - Pit bike grade adjustable rear shock - 380lb. rear shock spring rate **Pegs:** - Adjustable Mounting Position - E&C Designed Ultra Grippy Pegs - Reinforced and Replaceable Peg Mount **Brakes:** - New & Improved E&C pit bike disc brakes front and rear **Battery Pack:** - 72v 25ah - Hot Swappable (no tools required) - Expandable up to 72v 45ah **Battery Life:** - 30-50 Miles (stock battery) **Charging Time:** - 1-4 Hours (depending on charger) **Charger:** - 5 Amp Included; 12a Fast Charge Ready **Display:** - Bar Mounted LCD Display **Assembly time:** - 1 hour **Warranty:** - 30 days against manufacturing defects ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
