Very Light battery, love the difference in the balance on my Road King.
Fits great in my road king, I used the included height adjusters to make it a little higher. Worked out great, I get a very strong start up every time. The battery weighs practically nothing. Overall very satisfied with the batteries performance and the weight difference.

Very impressed!!
The media could not be loaded. I have an 1100 Shadow Spirit, the batteries for those don't last. (I remove them and bring them in for the winter.) I bought this one to try something different. So far I LOVE IT! My bike has never cranked over that fast before, not even when jumped from a running car. Fun fact, it's about the same price as a new lead/acid battery and much lighter. Easier to install than lead acid as well, it's shorter, but comes with plastic "legs" for height fit. I don't know about longevity yet but I am confident that it will go through a Michigan winter just fine. Highly recommend!!

Way more kick then stock batteries
I have 2 motorcycles. One is especially brutal on batteries (1990’s carborated). I’ve swapped both with Lithium batteries. Smaller (use the padded spaces provided), lighter, with way more kick than stock batteries.Thank me later!

Spacers shown were not included.
This should be a good battery and time will tell. But it was supposed come with spacers to bring it up to the height and width of a Group 20 battery. Not only were no spacers included, it did not have the bolts to connect the cables that all all producers of motorcycle batteries include.

Fits BMW R1200rt-good battery!
Installed in BMW R1200rt to replace AGM battery that never seem to last in this bike even with battery maintainers. So far, cranking strength seems good and no issues. Holds voltage longer than AGM as well.

Perfect replacement for YTZ10S
This lithium battery is 5 pounds lighter than the stock YUASA YTZ10S AGM battery and has the same dimensions. The Bosch holds 13.5 Volts and cranks very hard. Very satisfied.
