Parts Unlimited PJ1 Erion Honda’s Jake Zemke topped Friday afternoon’s AMA Superbike practice session at Barber Motorsports Park. Zemke turned a lap of 1:26.380 on his Dunlop-fitted CBR1000RR Superbike, quicker than Aaron Yates’ fast time from the morning practice (1:26.431), in spite of the 50-minute afternoon session being fully-dry for only the final 20 minutes.

Unofficially, Zemke also appeared to be one of the quickest riders during the damp first half of the session. However, Parts Unlimited Ducati Austin’s Eric Bostrom, who rides a Michelin-sponsored 999F04, was seen catching Zemke while the majority of the track was still wet.

Several of the top privateer Superbike riders – like Shawn Higbee and John Haner – did not go out in the mixed conditions of the afternoon session.
