You are going to suffer a miserable life with your perfectionist's outlook.
A scratch as you described is "patina," actually enhancing your car with that stress-marked look that comes with age and maturity.
The best way to have fun with a new motorcycle is to thrown it down, then jump up and down on it until the gas tank caves in and the fenders are dinged up one side and down the other. Then, you can start riding it without worrying about little scratches you can't feel with your fingernail.
