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.

Original Yuasa lasted 6.5 years. This is dead as a doornail after sitting for two days after its first ride. It worked after the ride, maybe it needs a tender at all times.On the tender, needs a miracle. It did charge enough to make a click, then nothing. Battery seems to really like the battery tender to stay charged. Will update as time passes. I was reluctant about the acid coming separate, but all well. And the price is right. Would I love to have a $200 battery? Not $200 worth. If you do not have e-start, I'm sorry.Read All Reviews

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.Read All Reviews

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.Read All Reviews
