★☆☆☆☆
Disappointing...
Customer service at BatteryStuff.com was excellent You can (and should) read the negative comments as well, but I was pleasantly surprised as Battery Stuff was very helpful in finding a replacement.
Though I can't recommend this product, I can recommend BatteryStuff.com
Low price.
Cons:
Did a nice job for a while, but despite occasional use and use of a Battery Tender Jr. the battery was junk after 15 months. I expect a battery to last longer than that.

buy it
I installed this battery as a 3rd attempt to get an electric start going on my KTM 300 2 stroke. The other batteries i've used were so weak I was starting to think my starter bearings were bad and it was binding. This battery spins the starter so fast, the bike screams to life in never longer than 1/2 a second of turning. Its truly amazing compared to others, and its the cheapest. No i don't work for the company, I'm here buying my second one just to look at.
Cons:
They don't sell these locally, just yauza shit

This is my first escapade with a AGM battery. It certainly does it's job. How can something this small pack so much punch? Conventional lead-acid batteries are a thing of the past. I have one of these in my 93 Harley, 82 Honda Gold Wing, 37 HD flathead and my 47 knucklehead but the last two are kick start

YTZ7S Scorpion 12v 120 CCA AGM battery
Only been running this battery for 2 months - not long enough in my opinion for a thorough review. As a mentioned previously, this style battery takes care of all the problems we grew accustomed to with vintage batteries. With the addition of an electronic voltage regulator, the charging system is now one less thing I need to be concerned with. Output at idle is negative - meaning, the battery must carry 100% of the load while stopped. This normally consists of the headlight, brake light, 2 turn signals flashing, plus, still have enough power to produce spark in the battery-powered points ignition system. Since I fried my last SLA by overcharging, this one has been doing it's job. Time will tell of it's longevity, but I've had great luck with AGM's in the past.
Extra capacity for my '74 Yamaha RD350, no acid to spill or leak and burn paint off, tolerant of lack of maintenance (sitting extended periods without a charge), no adding water, and the price was right! Can't beat that.
Cons:
None so far, other than some shimming to make this fit snug, and wiring different connectors on from the SLA battery I had prior. All nitpicks here ... very simple to fix.

Not as good as expected
Good fitment for the OEM yuasa in my KTM 450exc
Cons:
Not as good as my previous scorpion for my KTM 2 stroke. That one is going strong for over a year, no issues. I use battery tenders on on my bikes including this one. This one on battery tender as well. Didn't have enough juice to crank over In the middle of some trail work, left me kicking to get out of the woods.

Strong and Durable
I am looking for a battery for another motorcycle now, and I am torn between the Scorpion and the extra cost of the Scorpion Stinger. I will talk to Battery Stuff on Monday to find out more about the Lithium Ion Stinger.
Very strong and durable battery. I am going on 3 years of service with this unit in my BMW R1150R, and it is showing no signs of getting weak. I do keep a Battery Tender charger on it when I am not using the motorcycle.
Cons:
The terminals are slightly different than the OEM, so we needed to make a rubber cover for the positive terminal to protect it from touching metal above it.

Excellent factory replacement for less than half the cost
Batterystuff.com is the only place to buy batteries for your recreational toys
Bought 2 of these batteries for my boys Yamaha Raptor 250's. They fit perfectly in the factory position and have been excellent replacement batteries so far. We did put them on a battery tender overnight before install, but they had some charge right out of the box so not sure that was necessary. I have purchased batteries from batterystuff.com in the past and am very pleased with this outfit. Great prices and fast, free delivery :)
Cons:

This is not my first Scorpion battery purchase.
This is not my first Scorpion battery purchase. The first one I bought out performed a battery 3X the cost and outlasted it 3X also. So when time came for a replacement on my '15 Husky, I went again with the Scorpion brand. It has only been a few months now, but no complains. If it lasts only half the time of the first Scorpion, it still will be a bargain. BatteryStuff service and shipping time along with price was outstanding! Great job people!
