Mighty Max Battery YTZ10S 12V 8.6AH Replacement Battery compatible with Yamaha 900 XSR900 16-21 - 2 Pack
The Mighty Max YTZ10S matches the OEM battery spec for the XSR900, fitting the stock battery tray without modification and delivering the 12V 8.6Ah capacity Yamaha's fuel-injected 890cc triple requires for reliable cold starts. The two-pack offers solid value if you're stocking a spare for touring or track days. Caveat: being a sealed AGM unit, it won't match a premium lithium battery's weight savings.
