Transform your KTM RC 390 to how it should have been delivered from the factory with the BoosterPlug fuel injection performance upgrade.
No need to spend a small fortune on complicated devices like the Power Commander + endless setup problems, to make your bike run like it should have from the factory.
No complicated mechanical work or programming is required when installing the BoosterPlug. You simply plug it in using the original connectors and you are done. This is by far the best way to eliminate the common lean mixture problems.
Release the full performance potential in your motorcycle with the BoosterPlug upgrade:
- Improved and softer throttle response
- Stronger acceleration
- Say goodbye to the low speed surge issue
- Takeoff made easy by the stronger idle
- Reduced popping in your aftermarket exhaust
This version of the BoosterPlug covers all versions of the KTM RC 390 from 2017 to 2020.
If you have an older RC 390 model, you can find the BoosterPlug for it in the related products below.
Please note that we can not build a BoosterPlug for the "2021 and newer" model due to new emission regulations. You can see the detailed explanation here
