Dirt Bike Batteries
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.

YUASA Standard Battery without Acid
Ryan in KS
Solid batteries
Nice they offer without acid for guys that have bulk acid. Saves shipping cost and saves the buyer a decent bit of coin. Yuasa batteries are solid for the price. Got the old ct90 this went in having juice flowing through the harness for the first time in over a decade!

Shorai Lithium-Iron Battery
Terrell in AL
Great Battery
The battery was smaller than I expected but there was plenty of foam pads included to fill the space in the battery box on my Kawasaki Super Sherpa. It charged to full capacity right away. No problems at. When changing batteries in my bikes I always use Shorai and have never been disappointed in their performance.

Antigravity Batteries 8-Cell Small Case Race Use Lithium Battery
Gregory in CA
Great battery, light and compact
Finally installed it, very light weight and smaller dimensions so I used foam (leftover from shorai) to better situate it...and also keep some of the top clearance for the cables to attach with the additional wires for (trail tech voyager pro, sicass lighting harness, deltran battery tender plug). The thing I still need to used to is they need that wake up shot, so the forst crank might not start but the second does.

Antigravity Batteries Re-Start Lithium Battery
SHAUN in UT
Fits well in a '24 KTM 890 Adventure R
One of the biggest selling points of this battery, is the Restart feature. Where the KTM 890 is so power sensitive, I've actually had my screen go black and bike shut down because of low power on the stock battery. I bought the quick linking remote to go with it, so I don't have to peel the seat and cover back, just to hit the Restart button if needed. I weighted this battery compared to the stock battery, and it came in 86.3 ounces lighter!! Amazing! The only reason I didn't give it 5 stars, is because its basically double the cost of another brand. I did like the idea that it has 330 CCA vs 280 on the other so I guess it does provide a little bit more value in that aspect. It also fits in the stock battery tray without needing the foam filler pads to take up any extra space.
