Looks well kept and same colour as the one I have. Welcome to the CBX 750 club and they are more rare than SOHC! Could even be Honda's last aircooled 750 inline four cylinder.
I haven't seen those tires before on one, what make are they? Just changed my front and used a Bridgestone BT 45 which it had on previously. I know there's not much choice but can't find anything wrong with that one so no undue concern.
I've got an official Honda workshop manual so if you need any specs or data let me know.
An important point if you don't have a handbook with it, checking the oil level you do by unscrewing the dipstick / filler and wiping it then dip the oil level without screwing it in, the oil level is higher like this than with the stick fully home. Also, when draining the oil, there's the sump drain plus another on the frame tube to empty the oil cooler circuit.
Hope you enjoy it.
