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.

Been an awesome battery in my DR-Z400S. Fit the OEM battery box with just a little persuasion.Read All Reviews

Employee of RM ATV/MC and my wife actually got this as a gift for me. Went out riding for the day, and totally forgot that I had left the keys in the on position in the truck. (2012 Ram 1500) 7 hours later, I get back and realize my truck won't start. (It can spin the crank just a bit, but stops and just clicks.) After trying to call some buddies to come help me, I remembered I had this stored in my truck! Read the instructions... to be sure not to blow anything up, but easy hook up! Thenwhat do you know, cranked right over. Let it run for about 20 minutes and good as new! I would for sure recommend this as like a backup, or as a just in case situation!Read All Reviews

I have a 2002 Ktm 400 EXC. It has been a pain in the butt since day one. Battery has always been too weak to start bike. Have tried 5 different batteries including another Lithium. Just move frustration. Always drains trying to start bike. Not with this one. Amazing battery. Can crank the bike and she fires right up. No more drag. Hit the button, she cranks quickly and starts as suppose too. One of the best buys I have made for a bike. Just buy it. And it is small, need the enclosed spacers.Read All Reviews

I put a 440 big bore kit on my Honda 400EX and the regular battery had trouble turning the engine over. This battery has no problem starting it and is a fraction of the weight that the old battery was. I even bought one of these batteries for my YFZ450 now, too.Read All Reviews

Battery is great and was easy to prep with the acid. Note two conflicting sets of instructions came with. One said to wait 30 minutes plus after I stay the acid before charging. The other didn’t. I waited. Also note that Pioneer 500’s come with the 16 amp-hr rated battery not this 12 amp-hr one that RM’s site said was the correct battery. The 12 works fine but next I’ll get the 16.Read All Reviews
