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.

  • Shorai Lithium-Iron Battery

    Shorai Lithium-Iron Battery

    Douglas in OR

    Expensive but works well

    I put this on my 2014 XCW 300 trying to problem solve what was an issue with my electric start not working correctly. Unfortunately the battery wasn't the issue the starter was. But with that said I'm not unhappy I purchased this battery. If I had this battery to begin with my starter wouldn't have gone out as soon. I had to push the button multiple times to get it to start putting the starter through extra work causing it to go out after 4,000 miles on my bike. One push of the button now and it starts. It's expensive and that is why the 4 stars. You really should use a Shorai charger to charge it once a year. The charger is also expensive. IT IS RECOMMENDED AT COLD STARTS THAT YOU KICK YOUR 300 KTM. IF YOU DO THIS YOUR STARTER WILL LAST MUCH LONGER. COLD STARTS ARE VERY HARD ON YOUR STARTER.

  • Ballistic EVO2 Battery

    Ballistic EVO2 Battery

    Phil in IN

    Great Battery - major change from the lead junk

    Works great, the only issue I had was the smaller size - compared to the original overseas junk (I ALWAYS BUY MADE IN THE USA - WHEN I CAN - too bad I ended up with a KLR for the commute to work), called you guys - came up with the solution of my manufacturing a hardwood spacer (or shell) with vent holes for heat reduction. Also I will add baffled plastic around the Blallistic battery to cushion it - that should do it. VERY HAPPY with your produces and Website.
