Great fit for my 2025 Indian
Amazon says this battery wont work with my motorcycle. Its a Perfect for Indian Full Dress Bikes I have an Indian Roadmaster Darkhorse elite 2025 The Kenimoto YTX20L-BS with 12v 12ah and 960cca Has exact same measurements as the Polaris GZY20HL-C (4082949) 21.1ah and 320cca (knowing the difference between Ah and CCA is important to know what battery and why a battery will work for your vehicle is important) fits perfectly: started and stopped bike on and off rapidly 6 times and it started fast and smooth every time. Seems to charge right in the correct range while running, roughly around 14.3volts. I will see what happens with the next few trips and update. The reviews for Kemimoto are hit or miss I've had some things come in damaged but they have always corrected the situation. I personally like their stuff and at good value, plus customerservice has come through on the items that did work as inyended Come back for long term feed back installed Jan 5 will give a 1mo, 3mon and a 6mon update

Awesome KEMIMOTO Motorcycle Lithium Battery
My 2022 Honda Goldwing DCT original battery wasn't holding a charge. I watched a video on You Tube Woodzman Adventures and he installed the KEMIMOTO Lithium Motorcycle Battery on his 2023 Honda Goldwing. I followed his instructions and installed the same battery on my 2022 Honda Goldwing DCT. It was very easy to install, it fit perfectly and started right up. The price of the Battery was very reasonable. I'm very happy!

The battery sparked and melted
Installed this replacement battery on my son’s ATV. The first use was fine, it fired up as expected. The second use it started smoking under the seat, I shut the ATV off, pulled the seat and took a video of the Positive cable melted and smoking at the terminal as well as a hole melted on the top of the battery… the battery was installed correctly. I’ve read reviews that said this and didn’t think much of it. I should have…

Smaller, lighter, good power, easy to attach cables
Smaller than ag battery. A good assortment of spacers are included to keep it from rattling around. Mounting post have multiple options (directions) you can attach.not sure how well or long it will hold up but I’m happy now.

As stated
Only had it installed for a week so not sure how to rate it. It’s very light weight and fired up the go cart.

I purchased this battery after replacing the battery in my CRF250X with a lithium 2 years ago. The prior lead acid battery would lose charge quickly after attempting to start the engine more than 2-3 times (ethanol gum building up). The combination of adding a high quality fuel stabilizer, a JD jetting kit and adding the Lithium battery replacement has eliminated starting issues with the bike. I purchased this unit for my son's TRX400 to solve the same issues. Love the light weight. Just be sure to get a Lithium Ion compatible trickle charger for these units when in storage to avoid problems.

This battery fit perfectly and the fact that it is lithium and that it is lighter along with be able to go longer between charges if not used makes this a perfect cold weather motorcycle battery. I've had it for over a year and am loving it. Definitely recommend.

So far so good. I put it in a 2010 Ducati Multistrada S & it cranks it over with no issues. I also like the double posts. It makes attaching the positive & negative cables very easy

Really good value and good use in a race car. Has lots of cranking amps to start the engine, and very light weight. Capacity is low which is why it's best suited for something that doesn't need a lot of reserve life.

Working well. With battery's its a long term game. Battery posts have threaded holes on the sides to be able to have the battery installed on its side.
