Looking to buy used or if anyone can direct me to a good new controller I've been looking at the vesc but the almost seem to cheap to be true
Before you buy another controller...do you know how much loading your riding conditions are putting on the system? Meaning, how much power it actually requires to do the job you need it to do?
You might be having controller issues from insufficient power (or rather, excessive load for the power you have), wrong gearing, etc.--these are pretty common issues that can blow up controllers (which should be designed to not do that, but commonly aren't).
Another issue is that if you get FOC controllers (which are likely to give you better / more efficient performance when correctly setup for your specific hardware and conditions), you do have to set them up for your specific hardware and conditions...which can be time consuming and often frustrating, especially since many of the "auto setup" options don't correctly identify the hardware and have to be manually tuned. When the instructions are poor and software is badly translated (common with any technical stuff), that's a process requiring patience and experimentation, and will be different on every setup.
If you can live with plain old trapezoidal (noisy) motor drive, then the "generic" controllers that don't have any setup software or computer connections will be far easier to setup--you just wire it up and find the right phase/hall combination for the motor being used, and go. There's no tuning, etc. to frustrate you, but...there's no tuning...so you get what you get and there isn't anything to do to improve behavior if it isn't quite what you want.

I’m fairly new to ev world but I have an electric motorcycle which is designed to look like a Ducati can’t remember the name as all the stickers where ripped off but it has 10 kw motor it has 72 v battery it’s fairly big bike it’s rated to do 140 km/h I originally had a fairdriver controller but after buying 5 bluetooth dongle s and not,single one working and every time Id ride it it would cutout after 5 to 10 mins of riding. I couldn’t get it to connect to the app and the poor customer service I sold it. So honestly I don’t mind if it’s old and generic I just want something to work that’s easier to program or something I can just wire and go. Kelly referred the kls72120rm I accidentally shorted a wire which blew it up. But I really just want to ride my bike it’s been months since I got it and literally rode it for a total of ten mins 10 times and getting super frustrated.
So do you have any components for your build currently, or in the process of planning and purchasing the parts? Do you already have the battery, and if so, what are the specs?

I just need a controller and wiring harness
Picture didn't post. Kelly, Sabvoton, and FarDriver seem to be the popular controllers for that power level. There are others, but prices can be high.
Check the Electric Scooters / Motorcycles subforum. I recall Eastwood going back and forth on his controller decision, so I suspect he did a lot of research. He ended up going with a VESC based controller, I think, but was looking at a couple of FarDrivers.
Suzuki RMZ 250 EV Restomod
Picked up this 2007 Suzuki Rmz 250 frame and swingarm. Also came with the triple clamp and rear shock. First priority is to get this into a rolling chassis. Will restore this frame before mounting the motor and figuring out which battery to build or buy. I’ve ordered the front fork tubes...
