great product

Comments On Apr 13, 2016:good cranking straight out of the box. its hard to say if the Li batt cranks more/less than a fresh OEM. the battery is well packaged w/ good instructions on warranty and maintenance. light, very very light-if that matters to you.
ive recommended the Shorai to all of my woods buddies.

Super Light, great cranking power

Comments On Feb 22, 2016:I love this batter. It fits perfect, is way lighter and has great cranking power. It's definitely more than a "standard" battery, but this is a modification that I think is well worth the extra spend.

Never had a problem

Comments On Jan 31, 2016:Ive got these batteries in my gsxr and yz450fx and have never had any issues with them. You can use the deltran battery tender jr. lithium to tend them while not in use, which is a much cheaper alternative than the shorai system. They are expensive but you get what you pay for.
