Mine came with black levers, and they're long throw for sure. My old touring bike has butterfly brakes on it, and they felt way too squishy with the Bafang levers.
Easiest way I can think of to measure is to attach a brake cable to it, pull the loose (brake) end tight, measure the amount of cable hanging out the end of the sheath. Then pull the level all the way in, measure again, subtract.
