ETM RTR High Torque Mod Motor: Big Bottom-End Gains, Drop-In Install
The High Torque Mod Motor is the ultimate upgrade for RTR riders who want to boost performance without changing out the entire system. It is designed to work with the stock ETM RTR controller and delivers serious bottom-end power. No tuning, no guesswork, just more muscle where it matters. It is the most impactful power upgrade per dollar for the ETM RTR.
✅ BIKE FITMENT
Features
- Larger rotor and stator increase output and efficiency
- Thinner laminations reduce energy loss and sharpen response
- High-grade materials allow a 30°C higher operating temperature (requires the Mod Motor tune service)
- Smoother throttle delivery, cooler running and a big jump in torque off the line
- True drop-in solution that keeps OEM fitment and works with your factory controller
Note: This motor does not increase kW output. It increases torque per amp, which delivers the gains above without requiring a bigger battery or controller. To unlock the 30°C higher temperature threshold, you must purchase the Mod Motor tune service separately. It is not required. The motor still runs with all the benefits above and stays cooler without it. The tune is generally recommended for riders who race competitively.

Frequently Asked Questions
Does it work with the stock controller?
Yes. It is a true drop-in solution that keeps OEM fitment and works directly with your factory controller.
Will it increase my top power (kW)?
No. It increases torque per amp, giving you stronger bottom-end pull without a bigger battery or controller.
Do I need the Mod Motor tune service?
No. It is only needed to unlock the 30°C higher temperature threshold and is generally recommended for competitive racers.
High Torque or High Speed, which should I get?
Choose High Torque for low-end punch on the stock controller. For top speed with the TruMoto 6+7 kit, see the ETM RTR High Speed Mod Motor.
Can I use it with the TruMoto 6+7 kit later?
Yes. The 13kW TruMoto 6+7 Mod Powertrain Kit works with the Mod High Torque motor, up to 50 MPH on 72V.
