Amazing power and weight savings!
Bought as a replacement for my Yuasa YTX4L-BS in my 2014 KTM 250 XCFW. Dropped right in to the box and only had to use a little of the included foam to secure it. The brass terminals are top notch and the overall construction is premium. It's about 2 or so pounds lighter than the stock leaf acid. The cranking power is unbelievable now compared to stock. I have a dual sport set up with lots of accessories and lighting and this thing powers it all very well. If you're thinking about buying one, make sure you invest in a proper lithium charger too, like the Optimate. All in all extremely impressed with this battery and will be puttting nothing else into my bike from now on.

Nice size and weight, more power than you would ex
I use this battery on 550cc Vintage Honda’s right up to 870cc Vintage Cafe Racers because of its small size and strong output. Only caution is to not overcharge max 13.6 volts or discharge under 9 volts as it will kill the battery .

It’s a battery, it works.
Not much to say, I needed a battery and this one was recommended. Been in a month and no issues yet. Cranks the bike fast.

Works Great!
I had a mid-range Lithium battery with 150 CCA. It was always slow to start and at times the Bendix wouldn't engage. After getting my top end redone it wouldn't engage at all any longer. I upgraded to this 240 CCA lithium battery and, wow. The bike starts before I hear the starter most times now. Plus it's lighter and smaller than the stock battery. It is among the higher priced batteries, but well worth the extra money if you are upgrading to Lithium. Don't waste your money on Lithiums with low CCA.

Most Powerful and Smallest Battery
Bought this battery for my dirt bike that has a long history of problematic starting. The bike does not have a kick starter but for a significant amount of money and effort, a kick starter can be installed. There are also 24V modifications that many with this bike have had good success with. In the end I decided to keep the 12V system, skip the kick starter, and just install bigger battery cables, a new more powerful starter, and a battery with the biggest amp rating that I could find that would still fit in the bikes battery compartment. The AG-801 Small Case Antigravity is it. All I can say is after 2 months, this thing is a significant improvement. However all this comes at a price. This is a very expensive battery. But for my application it was the cheapest path to reliable starting.

One of the most powerful batteries out there
Got this for my KTM freeride, which is notorious for hard electric starts. Works very well. EarthX is good too. Shorai not bad. Others I have tried just do not compare.
