Delete this machine from profileSelect this machineWhen 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.

This battery is absolutely amazing, it has plenty of power to start my yamaha big bear 400 with ease. Just fill it up with the supplied acid wait 2 hours for the acid to settle, then charge it up and you're good to go!

3rd battery I've used on this bike. The others were cheap and standard AGM, so not great batteries to begin with. The Shorai however is unbelievably powerful! With 210 cold cranking amps it fired the bike right up with no hesitation! Very happy with this battery, I'll probably make the switch to these on my other 4 machines. If you get one of these don't forget to buy a lithium iron charger to go with it, The battery I bought was pretty well charged on arrival, but I followed the instructions and fully charged it before first use. Awesome battery!

Used this on my sportster and it is a massive upgrade. the stock battery is so big that it split my ground wire from it being smashed over. with this battery i had so much room and no stress on the wires.
