I am very happy with the purchase it was exactly as ordered. It did take a week longer but these things happen. I followed the instructions and had it working the very same day! Also I save $100 over the local bike shop quote! 😊

The exact battery I needed to get my old 04 r6 running again. I've used other batteries in the past but have always had good luck with Yuasa and it's becoming harder and harder to find them near me. Glad to have found it on Amazon.

I had to replace my stock battery after several years of stellar performance. I looked around a bit online and found various conflicting reports about what type of battery is best. In the end I decided to stick with the same brand as OEM since my original battery lasted so long. This battery arrived quickly thanks and was very easy to fill. The battery itself has barbs which then puncture the seal on the acid container, ensuring that you don't spill any while trying to fill and also eliminating the need for any type of funnel. Since the acid is then absorbed there is no risk of the battery leaking (though you still need to seal the battery to ensure that no foreign materials contaminate it), which is good because my battery mounts on its side. My bike cranks up very quickly, barely requiring me to tap the starter. All in all, I am very happy with this purchase.
