CB CHROMEBATTERY YTX9-BS 12V 135 CCA AGM – Maintenance Free Powersport Battery for ATV, Motorcycle, Scooter – Fits Honda, Yamaha, Polaris, Suzuki (T3 Terminal)
The CB ChromeBattery YTX9-BS is a solid match for the Kawasaki Ninja ZX-4R, which calls for a YTX9-BS format battery. The AGM construction handles the bike's vibration well and requires zero maintenance, which suits a performance-oriented machine you'd rather ride than fuss with. At 135 CCA, it delivers reliable cold starts. Caveat: some riders report it runs slightly smaller than OEM dimensions, so confirm fitment in your specific battery tray before committing.
