Welcome to the site !!
The cables are specific to your bike , you need to get the correct ones , either from your dealer (I prefer OEM on throttle and clutch cables , as I have had too may issues with aftermarket not fitting or adjusting correctly) or a local bike shop ...or here if you like) , just getting a random cable that looks kind of the same will cause issues , and maybe even injury , so I would not recommend getting anything other than what is specifically made for your bike ... In other words , replace the entire cable with the correct one/s , housing and all , do not try and crimp fit universal cables , or you may end up having a throttle stuck wide open when you do not want it to be , they are not expensive ... (around $35.00 for the set) or you can get the individual cables (push/pull) , but if one is bad , chances are the pair needs to be replaced ...
If $35.00 is too much , then try EBay and find a used one/set , you may luck out and find a set in good shape real cheap ...
