as a rider of a chain drive thumper for over 25 years gn00, i would never go back to a chain. to many maintaince issues. i've had cheep ones, good ones, really really good ones. they all streched way to much. torque issue i believe. compare the belt on the savage to a h-d. the savage is much bigger and beefier.
i know others will swear it's the way to go. i'm just speaking from the experiences i personally know of.
let the debate begin. chains suck and belong on farm equipment.
