Starter problems

I’m new to forum so pardon my ignorance. I have a 96 trx 300. Won’t start. Solinoid clicks but starter motor does nothing. Battery is new and a strong 12v. Have continuity from battery to relay (solonoid). Have 12v from input terminal on relay to ground. Have 12v from output post on relay to ground when I push the starter button. Have continuity from output of relay to terminal on starter. Get 12v at starter when I push starter button but starter does not turn. Nothing happens if I short across the poles of the relay. Is this most likely the starter motor?
