If anyone needs a battery, Amazon currently has the
BTL12A270CW for $125 minus a $45 coupon. That's the "upgraded" YTX9-BS replacement, and should work in place of the YTX7-BS in many cases too (based on
Battery Tender's Application Guide and CZroe's info in the first post). It's $140 on BT's site. The bigger models ($165-$200) have 45% off coupons instead, if you need something for a different bike.
I assume these are Black Friday sales, so you probably want to get it sooner rather than later if you're interested.
