I’m in the process of rebuilding a F650CS/GS. I priced it all out and it seems like it’ll be cheaper than just buying a BMW F650GS Dakar (I used to own one). They’ve shot up in price, sometimes over $4,000+ in my area. Which sucks, I bought mine fully decked out in Touratech gear for $3,000 back in 2016.
Anyway I got a F650CS frame and F650GS sub frame for $200. Slowly collecting parts to make it a rolling chassis. I’m planning on using the F650CS swing arm since I don’t want to weld too much. I’m wanting to run a custom ECU to have more control over this single cylinder engine. I stumbled across NanoEFI, which sounds amazing and perfect for my application. Trying to find a motorsports ECU that supports a single cylinder is such a pain in the ass. I know that no one has done something like this with the F650CS/GS.
But I hate when people tell me, “its not cost effective” or “Get another motorcycle” or “Lol noob”.
Well I’ll be documenting the build in different places but I’m going to be watching this project like a hawk.
