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.

Coming from a two stroke KTM I felt like the stock battery on the 4T Yamaha had a slight delay and more an issue for restarts when in motion and making a mistake in technical riding so based on reviews and prior experience this battery definitely starts the bike more easily. I haven't had the chance to truly test in motion starts yet, but it is clearly stronger than stock.

After two pre-filled and sealed batteries from a different brand, I got this one, and as it comes dry, there's really not much that can go wrong with it. I kinda wish I could have had a sealed as it's for my kid's bike, but the fact that it takes and holds a charge is a lot more important than one that is non-spillable but wont actually start a bike.
