E&C TruMoto 6+7 13kW Revolver Upgrade Kit | Compatible with Razor MX/SX Builds

We took the proven Revolver Motor from our ETM RTR and adapted it specifically for Razor bikes—creating the largest bolt-in motor ever made for the Razor platform.

Combined with a heavy-duty 420 chain conversion and the fully tunable TruMoto Little Bit V3 Controller, the 6+7 Kit delivers extreme power, massive torque and RTR-level performance in a Razor chassis.

The RTR Revolver Motor—Now Compatible with Razor MX/SX Builds

At the heart of this kit is the same Revolver Motor used in our ETM RTR powertrain. Until now, installing a motor of this size and capability into a Razor required extensive custom fabrication.

The Revolver Motor features:

⚡ A larger rotor and stator for increased power and efficiency.
⚡ Thinner laminations to reduce energy loss.
⚡ High-grade internal materials for improved durability.
⚡ Enhanced thermal performance for harder, longer riding.
⚡ Massive torque with smooth, controllable power delivery.

This is not a smaller Razor motor pushed beyond its limits. It is a proven RTR motor adapted into a purpose-built, bolt-in E&C powertrain compatible with Razor MX/SX builds.

SWINGARM EXTENSIONS COMPATIBLE WITH RAZOR MX/SX ARE REQUIRED DUE TO LARGER MOTOR

Required Gearing:

10 inch rear wheel: 8t / 47t 420 sprockets (included) 

12 inch rear wheel: 8t / 55T 420 rear sprockets for E&C 6+7 / Alpha Revolver setups (NOT included) PURCHASE HERE

For 12inch rear wheel, a longer chain is needed, and cutting is required. You can purchase 92L Chain HERE

Heavy-Duty 420 Chain Conversion

Serious power requires a drivetrain built to handle it. The 6+7 Kit converts your Razor to a full 420 chain system for increased strength, durability and power transfer.

The larger 420 drivetrain is better equipped to handle:

✅ High-torque launches
✅ Aggressive acceleration
✅ Hard off-road riding
✅ High-power battery upgrades
✅ The full output of the Revolver Motor

It is a major upgrade over the smaller chain systems traditionally used on Razor builds.

TruMoto Little Bit V3 Controller

The TruMoto Little Bit V3 Controller gives you complete control over how your Razor delivers its power. Using the TruMoto mobile app, you can adjust:

✅ Power output
✅ Torque delivery
✅ Throttle response
✅ Throttle curve
✅ Regenerative braking
✅ Acceleration characteristics
✅ Additional advanced tuning options

Tune it for smooth, manageable riding or unleash an aggressive power curve that hits the moment you twist the throttle.

Real-Time TruMoto Dashboard

The TruMoto app also provides real-time performance data, including:

🔹 Speed and RPM
🔹 Power output and regenerative braking
🔹 Battery level and voltage
🔹 Live system information
🔹 Built-in 0–30 MPH and 0–60 MPH timers

Monitor your build, adjust your tune and see exactly what your Razor can do.

6+7 = 13kW of Absurdity

Pair the 6+7 Powertrain Kit with a compatible high-performance battery to unlock up to 13kW of power.

That means brutal acceleration, massive torque, serious hill-climbing capability and performance previously reserved for fully custom builds.

6+7 = 13kW—and 13kW in a Razor is completely absurd.

RTR Power—Built to Bolt Into a Razor

This kit brings our proven ETM RTR powertrain technology directly to the Razor platform.

✅ Genuine ETM RTR Revolver Motor
✅ Largest bolt-in motor ever made for Razor bikes
✅ Heavy-duty 420 chain conversion
✅ TruMoto app-based tuning
✅ Clean, purpose-built installation
✅ Up to 13kW of power

This is more than a motor swap. It is a complete transformation of the Razor platform.

RTR Revolver power. Razor chassis. Up to 13kW. Welcome to the next generation of Razor builds.
