Eugene Laverty continued to establish himself as the man to beat for the latest round of the World Supersport Championship at Kyalami after dominating second free practice.
The Irishman, a winner at the South African circuit last season, was a full eight tenths faster than his closest rivals ahead of final qualifying later today.
Hitting the top of the timesheets early on, Laverty was significantly faster than title rival Kenan Sofuoglu, the Turk proving the only other rider to breach 1min 42secs.
Michele Pirro was third quickest on the second Ten Kate Honda, while Matthieu Lagrive kept up his strong form on the Triumph to go fourth fastest.
Having spent the Friday learning the circuit, Chaz Davies and Gino Rea scaled the timesheets to set the fifth and sixth fastest times, ahead of experienced rides Katsuaki Fujiwara, Robbin Harms and Massimo Roccoli. Championship leader Joan Lascorz, however, was 1.6secs off the pace down in tenth position.
The second and final qualifying session takes place later today at 15.05GMT.
