I have a few bikes and my 2008 Kaw has the original battery. My wives Suzuki had her Yasua battery croak after 7 months but we got a free one. I would have expected at least 3 years with a tender but it's not happening. A few of my friends report the same thing and agree it's best just to get a new battery every 2 years.
I would like to get more years so I switched to the Odyssey brand battery and will report back in 5 years! I had to get a very expensive new tender.
Almost went Shorai Lithium but they are too new and unprooven for years. Odessey has been out for a while and has a good track record. Lithium batts also need a specialized tender.
Sucks to get stranded.
