What Vivo is saying is that you simply get the highest quality battery that matches the dimensions of the battery box. If the Yuasa fits, then get it. Try the battery catalog at the dealer or motorcycle shop. They will have dimensions.
You can also look into lithium iron phosphate motorcycle batteries, but be warned they will require a special charger to top up from time to time for optimum performance. They also cannot be deeply discharged too far past empty or else they cannot be recharged, so be careful leaving accessories on while the bike is off.
Alternatively, you can get a small portable jump start battery for emergencies.
I personally have a small charging pigtail to the battery that I plug in once a week.
