The Antigravity ATZ7-4 Lithium Motorsports Battery is a direct replacement in size for the Lead/Acid YTZ7S found in so many bikes including most every Enduro bike on the market. This 4-Cell version is best for use in every day use scooter and bikes up to 250cc. Or Race bikes up to 450cc. It is an extremly lightweight replacement for the standard YTZ7S saving about 3.5 pounds while offering similar starting performance.
