Take the heart of the ETM RTR Alpha and bolt it straight onto your 2025 RTR or RTR Lite.

The Revolver Mod Motor & 420 Chain Conversion Kit delivers the larger, more advanced Revolver motor and everything required to upgrade your bike in one shot. This is the Alpha version (70H) of the Revolver motor, engineered with exotic materials and a 30°C higher maximum operating temperature (180°C) than the standard Revolver, making it ideal for aggressive riding and sustained high-load use.

What Makes the Revolver Mod Different

Larger Motor Design
Increased mass and improved thermal handling
More Torque Per Amp
Stronger acceleration without wasting power
Higher Temperature Limits
Runs longer and harder without heat fade
Designed for 420 Chain
Stronger drivetrain with reduced noise and lower maintenance

420 Chain Upgrade Benefits

The included 420 chain conversion replaces the smaller stock chain with a larger, stronger setup that:

Reduces chain noise
Increases durability
Lowers long-term maintenance
Handles higher torque with ease

Plug-and-Play Compatible

This kit works with the stock controller on your 2025 RTR or RTR Lite, making installation straightforward and hassle-free.

That said, to fully unlock what the Revolver Mod Motor is capable of, we strongly recommend pairing it with our Mod Motor Tune Service.

Mod Motor Tune Service Recommended

With the tune applied, you will unlock:

Greater torque output
More top speed
Higher temperature limits tuned specifically for the Revolver Mod’s materials

This is where the motor truly comes alive.

Limited-Time Entry Pricing

This kit is being offered at a special entry-level price for a limited time as a way for Electro & Company to support our existing riders and reward those upgrading their current bikes.

If you want Sport-level power, better reliability, and a quieter, stronger drivetrain without buying a whole new bike, this is the upgrade.
