The Brumbies pulled six points clear at the top of the Super 15 with a sparkling 34-20 win over the Lions in Johannesburg.
The Canberra-based franchise scored six tries, three in each half, and won comfortably despite kickers Christian Lealiifano and Jesse Mogg raising the flags with just two of their eight combined attempts.
The visitors trailed 6-5 in the first half following two penalties to Lions' five-eighth Elton Jantjes, but the Brumbies then piled on 29 unanswered points.
The bonus point victory gave the Brumbies seven points from their two games in South Africa.
While they weren't afraid to hoist the high ball at altitude, the Brumbies were most effective when they kept the ball in hand.
