While better technology exists, motorcycles of all kinds are going down the road needlessly carrying a heavy slab of lead. For just about every bike on the market, a better option exists in the form of a Shorai Battery. There’s no lead here, but rather, a well-engineered lithium iron phosphate power cell that provides more starting power, less self-discharge and a longer life than the lead-acid battery it replaces.

Each Shorai battery chassis is designed to be as small and as light as possible. And, while the chassis may look the almost the same as a conventional motorcycle battery, you’ll notice right away when picking it up that you’re holding something special. Depending on the machine, you can expect to save anywhere from 6-20lbs. off your bike’s weight. Power output aside, in terms of weight savings to value, there’s nothing else you can replace on your bike that saves so much weight at such a reasonable price.

For bikes with high-compression pistons or other modifications that make turning over the engine more demanding on the starter, the battery is ready for the challenge. Each battery is rated to operate at a higher voltage output than the stock unit it replaces. This makes a Shorai battery an excellent choice for performance engine builds. And when riding season is over, the battery’s low self-discharge rate means you can pull it out of your bike, put it inside and not have to worry about it becoming flat when springtime rolls around. Just install when it’s warm and go!

Shorai batteries require no special modifications to your bike’s stock charging system. Even the electrical poles are the same arrangement as the stock battery you’re replacing making installation a snap. And, because the power elements are fitted inside as small a chassis a possible, easily-cut foam blocks are included with each battery to provide a simple, quick installation in your bike’s OEM battery box. You can also use the additional space for fitting various tuning components, such as a Power Commander V, in that newly-available space.

Backed by a five year manufacturer warranty, you can buy with confidence. Read more about these batteries on our website here, then to get your own model-specific Shorai battery, give TJ a call on 866.931.6644, send a note to forum@ridersdiscount.com with SHORAI BATTERY in the subject line along with the model and year of the bike you’re riding, or just shoot us a PM and we’ll get right back to you.


Every Shorai battery comes with all required installation hardware and easy-to-follow instructions.

Smaller battery, more power. On the left, a conventional 30amp hour battery fitted to most touring bikes.

Each battery ships with an array of foam blocks that can easily be cut to accommodate the battery by itself. For anyone with a PC-V fuel controller, you can make arrangements for easily fitting the tuner within the foam blocks.

This Shorai battery is almost 20lbs lighter than a stock 30 amp hour battery.

Notice, the battery's charging posts are not installed out of the box, this allows the user to configure the battery's wires as needed for a clean installation.

Two different sets of hardware are included so as to fit a wide range of Harley-Davidson motorcycles.

The included hardware is of the highest quality to stave off corrosion for the life of the battery.
