| MOTOR |
The ETM RTR XL is powered by the E&C Revolver Alpha 65H IPM Brushless Motor. This high-efficiency motor is engineered for extreme duty, delivering a massive 16,000W of peak output. With a 180°C thermal rating and a wider powerband, it provides relentless mid-range pull and a top speed of 65+ mph, making it the fastest big-wheel pit bike on the market. |
|
The XL features a specialized power delivery system managed via the bar-mounted digital display. It includes Two Primary Power Modes plus a dedicated Hole Shot Mode:
|
|
| The XL comes standard with a high-capacity 72V 35Ah Samsung lithium-ion battery. Like the rest of the RTR lineup, it features a tool-free hot-swappable design with a quick-release seat latch. This pack is fully expandable up to 72V 45Ah for riders demanding maximum range and endurance on longer trail loops. | |
| The system includes a 4.5A Charger, providing a full recharge in 1–4 hours. The XL is 12A Fast Charge Ready, allowing you to cut down turnaround times significantly with the EMX® 12A charger upgrade, keeping you on the dirt instead of at the outlet | |
|
The XL utilizes the E&C Alpha Controller, a high-amperage unit specifically tuned to harness the Revolver motor’s 16kW potential. It is housed in an extra-rigid frame with integrated cooling and modular mounts, ensuring the electronics stay cool and protected even during aggressive, high-speed riding. |
DIMENSIONS & WEIGHT
| Bike Weight | 145 lbs (with battery) — precision-engineered to maintain a high power-to-weight ratio despite the larger XL frame |
| Wheelbase | 46.5″ (1180mm) — extended for high-speed stability and superior straight-line tracking on rough terrain |
| Seat Height | 32″ (810mm) — a taller, more natural full-size riding position that accommodates adults and taller riders comfortably |
| Max Weight Capacity | 250 lbs — reinforced tubular steel frame and firm-tuned suspension built to handle aggressive adult riders. |
| Tire Stance | 17″ Front / 14″ Rear — the “Big Wheel” standard, providing increased ground clearance and a more composed ride over obstacles. |
CHASSIS
| 🛠 REAR SUSPENSION |
The ETM RTR XL features a pro-grade E&C Tuned DNM Adjustable Rear Shock, valved with a Firm setting to handle the massive 16,000W output. This is paired with an Extra Rigid Extended Swing Arm and CNC MX-style axle blocks, providing superior high-speed stability and straight-line tracking that standard pit bikes can’t match. |
| Equipped with 48mm E&C Tuned Extended Fully Adjustable Forks. These forks are extended to match the XL’s larger geometry and are “Firm” tuned to provide pro-level bottoming resistance and front-end confidence during aggressive trail riding and jumps | |
| To harness the Alpha’s extreme speed, the XL is outfitted with 4-Piston Hydraulic Disc Brakes on both the front and rear. These high-performance calipers offer massive clamping force and superior heat dissipation, delivering reliable, “one-finger” stopping power with minimal fade even on the fastest descents | |
|
The XL moves up to a “Big Wheel” stance for maximum ground clearance and a more composed ride:

|
| The XL utilizes a high-strength 420 Moto Chain to transfer power from the 16,000W Revolver Alpha motor. This single-speed direct-drive system is optimized for instant torque and zero-maintenance simplicity. It includes Two Power Modes plus a dedicated Hole Shot Mode for maximum launch control. | |
