To test the starter relay use a multi-meter(find them cheap at harbor freight): Put the black wire on the negative terminal of the battery and then put the red wire of the multi-meter on the output side of the starter relay (the wire going to the starter), then press the starter button to see what kind of voltage you get. If its 0 when you push the button pull the red connector going to the top of the starter relay and check the fuse; if the fuse is fine, your relay is bad (side note, just because a relay clicks doesn't mean that it works). If you get low voltage then you need a new battery. If you get around 12V then check your starter; Is the positive lead tightened or cut that it's grounding out on the chassis? Are the mounting bolts tightened down enough to ground it? if yes, take the starter out of the bike and hook up 12V to it, does it spin? if it doesn't spin, your issue is your starter.
I literally just replaced my starter on my 05 10r myself and went thru all of those steps above and having to take the bike apart to get it out, so if you have any questions or need help feel free to message me.
