Yes 0.8 lb. if I breathed on it, it would go to 1.0 lbs so that is still 1/6th of the weight of the AGM lead/acid original battery. On a race bike it's the only way to go. Most all of the off-road and motocross bikes are electric start (except Suzuki ? ) and they either come with a lithium light weight battery or that is what mostly everyone goes to if the AGM battery needs replaced. My Super Duke is now well under 400 lbs down around the low 300 lbs according to the Summit Racing NHRA track scale.
