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.
For detailed battery recommendations, sizing information, cell options, and AMORGE ordering guidance, see:
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)

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
