It seems that a factory fault has made my crank shaft teeth snap and would cost more money to fix so i am looking for any engine that can be in its place that would fit and work.

The frame is smaller and different than any previous generation hyosungs that before it. Also it is the “only” fuel injected 125cc they have and all its electronics are locked to the 125cc (they will respond to that specific engine only)
Also, the frame also has mounting points designed around that frame. The frame is a bit weaker than the older generations for sure, so unless you have someone next to you who can cut the frame & fit some other engine from another 125cc bike that uses fuel injection , then “reinforce” it extra hard so the frame doesnt snap or twist or flex (structual warning)
Other engines = All electronics must come from the donor bike, otherwise you will have more hell trying to figure out the electrics.
How much does your garage cost to replace the crank for you ? At least if they do it, you will ride after the job is done.

me and my bike club are working to fix it but as i am only able to get parts form them, themselfs it gets a bit pricey but i have found the same engine on ebay thats only done 600 miles and got it for £200 so i am going to put that enigne in and most likey use the old engine as parts for the new one.
