    I have a chopper with a 125″ twin without compression release’s that was hell to try and start(even with the starter ring gear and pinion for the big engines).I tried other batteries that were supposed to crank this bike and be the most powerful and they actually blew the positive terminal right off of the battery after two attempts at starting(by the way the battery is mounted out of sight under the trans).I read about these guys in a popular magazine and was impressed with what I read so I gave them a call and I told these guys about my predicament.I got someone on the phone (no BS automated menu’s real people!)and they were very informative ,within a couple of minutes I had ordered this battery and it arrived a few days later and lo and behold this thing is a beast and spins this thing over like a sportster .This battery will start anything.This is also one of the best companies I have ever dealt with and will be dealing with in the future for my other projects

    Had a customers bike in the shop with a big cubic inch 11:1 compression motor that wouldn’t let any battery crank it over, even with compression releases… That was until I dropped the 12-24 in. Bike pops over like a stock 883 now. We’ll worth the investment.
