Luke Dorn grabbed four tries as London enjoyed a comprehensive 62-18 victory over a weakened Warrington side at the Stoop.
Dorn struck in each half as part of a 10-try Broncos assault as Tony Smith's decision to rest his stars ahead of the Challenge Cup final backfired.
Kieran Dixon, Will Lovell, Omari Caro, Michael Robertson (two) and Julien Rinaldi also crossed for Broncos while Stefan Ratchford, Richie Myler and Rhy Williams scored tries for Warrington.
