What a difference the years make. The exact same YTX16-BS today from the exact same website costs $90. Heh. I was hoping for some savings. BoohooI just bought a Yausa (highly rated) replacement sealed battery for my 1500 Vulcan, the same battery that you are looking for at $65.00. Yes there are places (dealer) that will charge you $130 for this batter.
YTX16-BS YUASA - USA SMF 12 16 6.01 3.4 6.13 + - 10.3 $65.08
Here is the online link where I purchased mine.
Motorcycle Batteries - Wholesale and Retail Motorcycle Batteries
YTX16 is a 14ah battery.The batt in the link says 16 Ah. Hmmm.
I guess I'll just pay the premium from ordering straight from the Kawi dealership... better than wasting my time buying the wrong battery.
