Hmmm. I can buy three regular lead batteries on eBay, delivered, for less than that special. I tried a lithium battery in an ST1300 11 years ago. Went back to lead. Can't remember why I didn't get another one, but the price could be a factor, although AGM batteries can cost that much from local battery specialists. It's chief claim to fame was its lightness. It required a packing block to compensate for its shorter height. The CCA was fine.
