Re: 2-stroke electric starter??
I would just put a small 24v hub motor on the front and use a couple of SLAs to get rolling. It's a proven, simple system that will cost less than the KTM kit and require no machining.
Another idea is to use just an electric hub motor (sans wheel) connected to the drive train with a jackshaft.
