I'm still on the original 2014 battery.
I had my 2009 650 set up the same way and it still had the original battery when I passed the bike down to my younger brother in 2016/2017 ?

He with the most toys wins.
Out of my depth in a puddle.
Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
