starter problems with 86 vf500f interceptor

I was riding in 95 degree f weather for about 3 hours when the bike just shut off at a stop sign. I turned the bike off and back on, and when I hit the starter, i just heard a click and the lights dimmed. I set the bike in the shade for about 20 minutes and still same issue.
I eventually was able to bump start the bike, and ride 2 hours to my home. came back to bike an hour later still same issue. just a single click from the starter relay. I checked battery connections, checked fuses, checked main fuse, checked the wiring to the starter solenoid...the battery seems fine although I havent checked with a multimeter. I put it on a battery tender and charged it, even tried jump starting with a car battery (car was off) no difference at all. did I fry the bike? what are my other options?

 

Check your main ground wire on the engine block and the main positive at the starter and starter solenoid for good contact. If all is good then your battery is probably fried.

 

Your charging system output may be too low to keep battery properly charged.
