Choose an 80V motor upgrade around the complete build and mounting arrangement. Confirm the exact motor version, wiring, wheel, controller, and battery requirements before ordering; a shared model number alone does not prove compatibility.
80V ONYX Motor Upgrades
The QS 260 V4 200mm and QS 273 V4 200mm are the most relevant aftermarket motors for the ONYX 80V platform.
Rumors indicate ONYX Motors is developing a larger motor similar to the QS 260 V4, but designed specifically for the 200 mm 80V swingarm.
An official ONYX motor would likely offer:
- Factory compatibility
- Manufacturer warranty
- Validated performance
- Community tuning data
- Long-term parts support
If your current motor is healthy, waiting for the official motor may be the most practical path.
QS 260 vs QS 273 on the ONYX 80V

| Size | Compact | Larger |
| Handling | More agile | Slightly slower steering |
| Acceleration | Quick | Strong but heavier |
| Thermal capacity | Very good | Excellent |
| Sustained mountain riding | Good | Excellent |
| High power builds | Moderate | Ideal |
| Stock compatibility | Excellent | Good |
| Suspension impact | Minimal | Higher unsprung mass |
| Controller needs | Stock to mid-range | High-current recommended |
| Battery needs | Stock to moderate | High-output preferred |
| Best use case | Daily riding | Extreme performance |
QS 273 V4 Mag 200mm on the ONYX 80V
The QS 273 V4 Mag 200mm installs directly on the ONYX 80V when paired with a 3.5-inch mag rim.
Mag-specific specifications:
- Maximum torque: 350 Nm
- Phase wires: ~5 AWG
- Magnet height: 50 mm
- Weight without tire: approximately 61 lb
- Peak power: 42 kW (unverified)
With the stock battery and controller:
- Installation is straightforward
- Performance gain is roughly 5-10%
- Torque delivery becomes smoother
- Thermal capacity improves
When the QS 273 Really Comes Alive
The QS 273 is capable of significantly more performance than the stock system can deliver.
To unlock its potential:
- Upgrade the controller (example: FarDriver ND961000)
- Use a higher-output battery (example: AMORGE RS50 or EVE 50PL)
- Tune the controller correctly
With these upgrades, the motor can produce dramatically higher torque and acceleration.

Motor Size Scaling: Torque, Current, and Thermal Capacity
QS motors follow a direct scaling relationship where physical size increases torque capability, current handling, and thermal performance together. These characteristics scale with stator size and overall motor mass.
QS 205 V3Ti (150 mm)
Smaller stator and lower thermal mass. Heats up faster under sustained load and reaches thermal limits sooner. Lower continuous current capability compared to larger motors.QS 260 V4 (155 mm)
Larger stator and increased thermal mass. Supports higher continuous phase current with improved heat dissipation. Sustains load longer before reaching thermal limits.QS 273 V4 (200 mm)
Largest stator and highest thermal mass. Designed for very high phase current and sustained power. Absorbs and dissipates heat more effectively than the 205 and 260, allowing significantly higher continuous performance.
As motor size increases:
- Torque output increases
- Allowable continuous current increases
- Thermal capacity improves (slower heat saturation and better dissipation)
This scaling also requires:
- wider dropouts
- thicker axles
- larger phase wires
These are linked characteristics, not independent changes, and together define the motor’s real performance limits.
Supplier and Configuration Checks
Confirm the exact 80V configuration and availability before ordering. Use the motor ordering checklist to document the motor, mounting width, winding, wiring, and wheel assembly.
