1980 HONDA TWINSTAR CM200T RIGHT HAND CONTROLS OEM | eBay
here you go
Hope everyone's new year has started well,
I am looking to get new hand controls for my '80 cm200t. The high low beam switch is broke on the left side and the push start button is also broke on the right side. Does anyone know of any controls that I could buy that will fit right into the stock wiring?
