Delete this machine from profileSelect this machineWhen 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.

This battery is crazy light weight. The box will feel empty when it arrives, but it's in there. It has delivered a very strong pull all year now. Even in the winter this can hold enough power to crank just like the summer.

Weight savings!! and piece of mind when travelling during shoulder seasons, or running multiple accessories off the bike.

It does exactly what's it's supposed too and fits perfectly as it is exactly the same dimensions as the stock on. Priced within reason I recommend to anyone who needs a battery.

For the rider who plans for the worst and hopes for the best. Compact and easy to carry. I have jumped more cars than motorcyles. Works so good I bought a second unit to carry in my 4 wheeled rig.
