Fuel Injection tuning on the Honda Monkey 125 is usually expensive and complicated. The BoosterPlug is a better and proven alternative.
No need to spend a small fortune on complicated aftermarket tuning devices like the Power Commander + additional parts + endless Dyno hours, to make your bike run like it should have from the factory.
We designed the BoosterPlug to be easy and fast to install, so it comes with the correct connectors to let you install it without cutting and splicing wires, and without the requirements of a lot of extra parts that will not fit on the Monkey 125.
A true plug and play solution that will make your bike so much better:
- Soft and precise throttle control
- Quicker acceleration
- No more low speed surging
- Stronger idle
- no more stalling problems
- Reduced popping in your aftermarket exhaust
This version of the BoosterPlug covers all versions of the Honda Monkey 125 from 2018 to 2020.
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
