I have some for sale. One is a YZ85 with the same motor, controller, battery. Or a KTM 2008 SX same motor and bigger controller and bigger battery. Start a conversation with me on ElectricDirtRiders.com and I can send you pictures and we can talk price. Both are street legal.
We build the complete thing, You give me a good roller, and between $4000-5000, and I can build you one with a good Molicel or Samsung cells. Wired Off Road makes a kit also. And it starts at $4000 www.google.com/search?q=kx85+to+electric+conversion+kit&rlz=1C1CHBF_enUS1099US1099&oq=KX85+to+electrc&gs_lcrp=EgZjaHJvbWUqCQgCECEYChigATIGCAAQRRg5MgkIARAhGAoYoAEyCQgCECEYChigATIJCAMQIRgKGKABMgkIBBAhGAoYoAEyCQgFECEYChigATIGCAYQIRgKMgcIBxAhGJ8FMgcICBAhGJ8F0gEJMjEzNjFqMGo5qAIAsAIB&sourceid=chrome&ie=UTF-8#fpstate=ive&vld=cid:289590a7,vid:NqNx-hhz6ps,st:0
