125cc HONDA GROM ELECTRICS ADAPTER KIT TO CBR 250/300cc ENGINE

This plug and play adapter kit allows you to reuse/keep your 125cc wiring harness/electric/controls with a CBR 250/300cc engine.

Just drop out your 125cc engine, install your swap bracket and CBR engine, then plug in all your adapters and you’ll be almost complete!

All that’s left to do is sort out a radiator with an independent fan and then an exhaust system.

The bonus with going this route and using this adapter kit  is that if you already have an aRacer ECU for your 125cc Grom, it can be reused! You won’t need to buy a new aRacer ECU for the CBR engine. 

The manual idle adjuster is also a must have as the plug for it that is on the 250/300cc throttle body does not come with an adapter because it doesn’t  work/isn’t possible. So that plug just unscrews and gets replaced with the manual adjuster. The manual idle adjuster can be purchased with the adapter kit or it can be purchased on its own at a later date.
