Honda cbr125r engine swap


Recommended Posts

Hi guys. I have a honda cbr125r 2004 model and basically the engine that's in it is not worth repairing. (Costs way to much)

I have found an engine to buy but it is from a 2007 model which is fuel injected rather than carb.

Does anyone know if there Is any differences between these 2 engines? Will there be any problems or will it connect straight up?

hi, i have a 04 plate honda cbr 125 r also, the engine in it is from a 07 cbr, so i can confirm they work just fine.

i didnt personaly do the swap myself as the person who owned before me did it.

but as mentioned they do work although im not sure if he had to do any additional work.
