This post breaks down the ONYX CTY2 platform, how it compares to the RCR, how Fallout Mode works, and how to safely increase performance using controller tuning and AMORGE batteries.
It starts with a simple overview of the bike’s hardware, then moves into power modes, controller settings, cooling upgrades, and battery options.
Quick Overview
If you just want the short version:
- CTY2 shares RCR DNA but uses a lower-power QS205 motor setup
- Stock peak power is 12,000W using a Kelly 6018 controller
- Fallout Mode unlocks full current safely with proper cooling
- The RCR motor + controller can be swapped in with harness mods
CTY2 vs RCR Hardware
The CTY2 uses the same QS205 motor platform as the RCR, but in a lower-power configuration.
| Part | CTY2 | RCR | |
|---|---|---|---|
| Controller | Kelly 6018 | Kelly 7230 | |
| Controller Amps | 100A / 240A | 120A / 300A | |
| Motor | QS205 V3Ti (10kW) | QS205 V3Ti (20kW) | |
| Motor Watts | 12,000W | 21,000W |
The CTY2 also uses custom wiring, fabricated connectors, and a dedicated service port for quick phase, hall, and temperature sensor access.
Fallout Mode (12,000 Watts)
Fallout Mode is the CTY2’s equivalent of the RCR’s Sicko Mode. It allows the controller to deliver full current for maximum acceleration.
You can run Fallout Mode on the stock 23Ah battery, but aggressive riding will drain it quickly.
For best results:
- Ride moderately on the stock pack
- Upgrade to an AMORGE battery for sustained performance
- Add cooling mods before heavy use

Fallout Mode Cooling Parts
Cooling is mandatory for sustained high-power riding.
Fallout Mode FAQ
- Can I run Fallout Mode without cooling mods?
Yes, but expect overheating and permanent motor damage.
- Will the controller overheat?
No. The controller is externally mounted and well-cooled.
- Do I need a bigger motor?
No. The QS205 handles 12,000W reliably with proper cooling.
- Cost and time?
~$140 DIY, or $150-$200 labor. About 1.5-2 hours total.

Final Notes
- Fallout Mode is safe when cooling is installed
- AMORGE batteries are the best performance upgrade
- RCR drivetrain swaps are possible but require harness work
- Stock setup is already fun - upgrades just unlock its full potential
