Pack weight is an approximate figure — sourced from zeromanual.com, motorcycle.com, ultimatemotorcycling.com. Zero doesn't publish most pack weights, so these are cross-checked against reviews and curb-weight deltas. Energy density is shown only where the weight is independently sourced, and is max capacity ÷ pack weight.
