Product Info

The Electro & Co Revolver Alpha Kit replaces the stock motor on a 2025 ETM RTR or RTR Lite with the Revolver Alpha (70H), the same motor fitted to the RTR Alpha, and converts the bike to a 420 chain. It works with the stock controller, and Electro & Co says it brings Sport-level power and a stronger, quieter drivetrain without buying a new bike. Everything needed for the swap is in the box.

Fitment:

  • ETM RTR (2025)
  • ETM RTR Lite (2025)

The Revolver Alpha is a larger motor with more mass, so it handles heat better and makes more torque per amp: harder acceleration without wasted power. Its maximum operating temperature is 180°C, 30°C higher than the standard Revolver, so it runs longer and harder before heat fade sets in. Electro & Co built it for aggressive riding and long stretches under heavy load.

The 420 conversion replaces the smaller stock chain with a larger, stronger setup that runs quieter, lasts longer, needs less maintenance and handles the extra torque comfortably. Gearing depends on your rear wheel: 8T front and 55T rear for a 12 inch wheel, 8T front and 63T rear for a 14 inch wheel. A 14 inch rear on a non-XL bike needs the chain cut to length or a 92 link chain, and sprocket style may vary.

After the install, set the display so speed reads correctly: the Sport column for a 12 inch rear, the XL column for a 14 inch rear. The kit is plug-and-play with the stock controller; for full performance, Electro & Co strongly recommends its Mod Motor Tune Service, which raises torque output and top speed and sets temperature limits to match the Revolver's materials.
