HD drive pulley is not on the swing arm pivot and the final belt drive uses no belt tensioning device. The do have the geometry set up so the belt is at maximum tension in the normal riding position (swing arm pivot in line with drive pulley center and rear axle bolt. The belt tension changes very little as the suspension moves through it's travel. The belt tension is set by deflection so it's sorta like tensioning control cables on an airplane.Do they actually make the swing arm pivot coincident with the drive pulley? If yes, that is way simpler than the tensioner but really puts a premium on keeping belt tension in the right range...
