Dirt Bike Battery

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.

    How does it do it??

    It is hard for me to believe something this light (I thought I received an empty box) can spin a 5-Honey this easy... Original battery took a few seconds to spin-up... not so with this one, even cold bike is running as soon as button pushed ...

    This battery works will In both my quads. The battery in my Raptor 700 went dead because I let it sit too long and I think there is always a slight current draw on this bike. I was able to charge it up and it works. I don't recommend letting any battery go dead but had this been a lead acid battery I don't think it would work. This battery weighs less than a lead acid, can't make a mess and so far has worked in all weather conditions. Very happy with purchase
