Harley and the Davidsons wrapped its three nights on Discovery Channel with the biggest premiere telecast numbers in more than three years for a single-network miniseries on cable.

The six-hour miniseries about the birth of the iconic motorcycle brand unspooled in two-hour blocks over three consecutive nights starting Monday. In Live + Same Day stats, Harley opened on the network’s so-called Motor Monday with 3.4 million viewers at 9 PM. Tuesday’s Night 2 clocked 3.4M at 9 PM; Wednesday’s final night nabbed 3.34M at 9 PM.

Across its three nights, the miniseries’ two plays clocked 2M demo viewers and 4.5M total viewers.

Harley and the Davidsons is Discovery Channel chief Rich Ross’ first miniseries for the network and part of his campaign to widen Discovery Channel’s scope. Signaling strong interest before the debut, the mini’s trailer clocked 7M views in about a week, outstripping any trailer ever posted to plug the network’s well-known Shark Week.

There was a 2017 Harley-Davidson motorcycle giveaway for the viewers and we’re sure the lucky winner is going to remember this show for the rest of his life.
