readings look normal.
Just check the voltage when you crank it. If it drops a lot it will indicating a weak battery. I still prefer a normal fast responding multimeter for this through.
Even if you have full voltage on the battery, an older battery might not give you enough amps to start the bike.
My garbage green tokiohama battery reads full but refuses to crank the bike after a few days of sitting. Im using a yuasa battery now and it cranks fine even after 2-3 weeks of sitting.
Also monitor the readings when riding. Sometimes a flaky rectifier might stop charging when it gets too hot.

my yuasa ytx14 is now 1.5 year old and still gives >300A CCA (it's rated at 200CCA).
i always tender charge/trickle charge the battery if i don't start the bike more than a week.
heck i always try to charge and keep it full weekly since lead acid don't like the charge to go <40%
using this imax multitype charger that i use for everything.
