If you are not in a super hurry I will be happy to walk to Honda and buy you one.
Maybe someone will be along later with a Thai parts exporter.
What is the build year of the Honda Wave 125R and where was it originally bought? Information like that is important, as a Honda Wave 125R from one years would not necessarily be the same as a Honda Wave/Supra 125R from the same year bought in Indonesia.
Guys, I am in need of a rectifier for my Honda wave 125R motorcycle. Could anyone help me to buy it in Bangkok letting me know the address and the phone number?
