Always have run Yuasa on my bike with no problems. Last one wasn't the high performance battery and it lasted 5 years. Installed the high performance this time and really cranks fast. It installed with problems and acid went in without a spill. Just follow instructions.
Given the simple do-it-yourself fill option I was assured of having a fresh battery. Followed advice on manufacturer's website regarding pre-use charge. Still only a month or so old and no problems. Expect long term 'name brand' performance.
This is a really light battery great replacement for the old lead acid stock battery's. I installed one in my 2001 GSXR600 and My wife 2009 Ninja 250R with no problem the price is the best for Lithium only had it for a mouth so time will tell.
