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.

Same battery as the original in my ATV. It lasted 5 years. The new battery is Easy to prep for installation and lasts for years of fun! If you need one buy one. you wouldn't regret it!

Installed in my Sherco 300 two-stroke to get better starting. It fit with slight modifications using foam blocks and trimming the stock battery hold-down. This was the highest cranking amp battery I could find that would fit, and I wish I did this years ago. It cranks so much faster and solved my weak cold starting issue that I always had even with a new stock replacement lithium battery. It'll even fire up in gear with a cold engine and the clutch dragging, where it would hardly turn over before. Only negative thing I can say is that the instructions said it would come with adhesive foam blocks to facilitate custom fit installations, but it only came with one foam block and no adhesive. I had to glue it myself and use additional foam that came with another battery.

My '17 450exc would always take multiple attempts to start cold with a 'normal' lithium ion battery, sometimes taking several minutes before it'd finally start. This battery changed it into starting on the first or second try. The terminals are in a slightly different location but they work fine.

I have been using Yuasa batteries for years . They are well built and almost always outlast other brands . This particular purchase was a 6 volt battery for a Honda CT 90 project and as always Rocky mtn. had this battery in stock . Their pricing is competitive and their shipping is legendary .

Yuasa batteries just seem to last longer and have great starting power. I've bought some cheap ones and they aren't worth putting in.

All batteries should be sold this way. Having the acid in a separate container just makes sense. That way you don't buy a battery that has part of it's lifetime already spent.
