Antigravity ATZ7-RS

The Antigravity ATZ7-RS lithium motorcycle battery is a lightweight, high-performance battery upgrade designed for riders who want to reduce weight, improve starting power, and build a sharper race or track-focused motorcycle. Weighing only 1.32 lbs and delivering 150 cranking amps, the ATZ7-RS is an ideal replacement for heavier lead-acid batteries in small-displacement sport bikes, race bikes, off-road bikes, supermoto builds, and lightweight custom motorcycles. Antigravity lists the ATZ7-RS as a YTZ7S case size battery measuring 4.53 x 2.75 x 3.35 inches, with 7 Ah PbEq / 3.3 Ah actual / 42 Wh capacity.

For racing, every pound matters. Replacing a traditional lead-acid battery with the Antigravity ATZ7-RS helps remove unnecessary weight from the motorcycle, improving the bike’s overall power-to-weight ratio and contributing to quicker transitions, sharper handling, better braking response, and a more responsive feel on track. Antigravity notes that its lithium batteries can be up to 70% lighter than equivalent lead-acid batteries, making the ATZ7-RS a smart upgrade for riders trying to reduce weight without sacrificing dependable starting performance.

The ATZ7-RS also features Antigravity’s built-in RE-START technology, which is designed to reserve enough power to restart the motorcycle if the battery is accidentally drained. The full Battery Management System includes protection against over-discharge, over-charge, thermal issues, and includes lithium cell balancing for safer and smarter lithium battery performance.

Whether you are building a lightweight race bike, upgrading an off-road machine, reducing weight on a track day motorcycle, or replacing an OEM battery with a modern lithium option, the Antigravity ATZ7-RS battery delivers compact size, low weight, strong cranking power, and race-focused reliability.
