Yuasa GYZ20HL Factory Activated AGM High Performance Battery

This new generation of maintenance-free batteries delivers higher cranking amps for vehicles that require extra starting power from the largest motorcycle battery manufacturer in the world.

Absorbed Glass Mat (AGM) Separators – an advanced battery technology that eliminates the need to ever add water. Advanced lead-calcium technology that holds its specific gravity more than 3 times longer than conventional lead antimony batteries.

Awesome step up! I got this battery for my 2012 H.D. Blackline. The battery is a beast compared to stock. Cranks the bike up very quickly. I definitely recommend this battery to other H.D. owners at the very least. July 22, 2015
