When you’re ready to ride at the motocross track or on a scenic trail, nothing beats the convenience of a good battery that is ready to go. So if your battery is on the decline, make life easy again with a new dirt bike battery from Rocky Mountain ATV/MC. We carry a variety of dirt bike batteries to suit every style and budget.
We have traditional lead-acid batteries, lithium ion batteries and gel cell batteries. We carry leading brands like YUASA, Ballistic, Shorai, Antigravity, Bike Master and more. All you need to do is enter your bike’s make, model and year, and we’ll show you exactly which batteries will fit your motorcycle. (If you prefer to stick with the OEM battery, just click the OEM button at the top of the page.)
Even if your existing battery is still going strong, there are plenty of reasons to replace it with a better aftermarket one. For example, a maintenance-free battery can remove the headache (and risk) of continually checking and adjusting acid levels. And if you’re looking for a lightweight motocross battery, there’s nothing better than lithium ion! It’s one of the fastest (and cheapest) ways to shave a pound or two off of your motorcycle’s weight.

Crazy good battery in comparison to the stock one that comes with the newer KTMs. Fires the bike up nearly instantly! Would recommend to anyone looking for a replacement. Price is a little steep but really is worth it

Great battery for the price. Quality is as good as the oem battery.

It fits my KLX 300 SM. However, I had to cut a sponge into 2 small pieces to lift the battery into the proper position because it's smaller and lighter than the original. The OEM cable ends were too small and a larger pair was provided in the box. But it was easier to drill the original holes larger and flatten out the metal with two needle nose pliers for better contact with the terminals. Overall it's a good buy.

Super light. Almost can't even tell it's there. Holds charge a long time.
