In here, just provide GEARBOX TRANSMISSION ASSEMBLY NO REVERSE, NO POLISHED. DO NOT INCLUDE THE SPEEDOMETER GEAR (#67).
Because of the no reverse transmission is very less, and very less people need it. So, I just sell whole one here, and do not provide parts options. Thanks for understand.
But if your transmission is real M1 no reverse one. And you strongly need some spare parts. Please contact us at first!
If you need With reverse one, please check M1M M1S 12 Volt parts CATALOGUE.If the selection show 0, you can double check with me. Maybe I can find, maybe I cannot. Thanks for understand.
