Battery for your Kawasaki EX250 Ninja R
The recommended part is a YTX9-BS. Match that code (or a listed equivalent) - powersports batteries are size- and terminal-specific, so the code matters more than the brand. Worth adding: a battery tender - sitting unused is what kills most bike and ATV batteries, and a tender keeps it healthy over the off-season.
