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.

    Great Battery

    I'm really happy with this battery and I have huge peace of mind knowing that I can use the re-start feature if necessary. I ride way out away from civilization, and am screwed if my battery discharges.

    Amazing Battery

    I was having problems starting my KTM in gear. A close friend suggested this battery. I thought it was a clutch problem, but tried the battery. It fixed the problem. Not cheap, but worth it!

    I have had this battery for two years now and love it. It is several pounds lighter than the stock battery and that weight comes right off the top of the motorcycle. I ride pretty regularly so it doesn't sit much, but when it has sat for a couple of months, It fired the bike right up, no problem. One time I accidentally left my Tusk lighting kit turned on and it drained the battery. I kick started the bike and within a couple of minutes it was back to full power. Spend a little extra and get a battery you will love.

    Battery Upgrade!

    Not sure if it's really a 5 star reliability battery yet, but time will tell. So far so good! It is lighter though, and the speed at which the motor turns over first thing in the morning is improved. Have not had to use the cold start yet either. Good Stuff!

    Great battery!!!

    Seems to work good. The fit was perfect. Terminals are a bit tricky but not too hard to get in.
