The M109R Boulevard is a motorcycle where the battery changed mid-run: 2006 takes the YTX12-BS and 2007 to 2014 the YTX20CH-BS. The plate above names the source for each year, and the table shows each run, so match the year to the case before you order.
For 2007 to 2014 that means the Ionic S4: 500 cranking amps, 3.3 pounds, the same case in lithium. Some trims of this model take a different battery; check the code on yours. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
