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.

Ive got these batteries in my gsxr and yz450fx and have never had any issues with them. You can use the deltran battery tender jr. lithium to tend them while not in use, which is a much cheaper alternative than the shorai system. They are expensive but you get what you pay for.Read All Reviews

I've had 2 of these, the first one lasted over 3 years so I can't complain. The smallest 4-cell cranks my bike well and the cold is not an issue. I accidentally drained mine completely a couple of times by leaving the switch on. It recovered without an issue except for the last time I did it which was 3 years from purchase. The second one is going strong at the one year mark.Read All Reviews

Take a look at the cranking amps - 125 - which is pretty close to stock. The battery is super light and seems well made and does a just fine job of starting up my bike, but not a better job. For a little more money, you can get a lithium that puts out 210 CA, which will start the bike a lot better. Hindsight, that's what I should have done. Next e-start bike will get a Shorai.Read All Reviews
