Scott Redding and Jack Miller led Moto2 and Moto 3 testing, respectively, on Tuesday at Jerez, where soggy conditions kept many bikes in the garage.
Brit Redding was quickest in Moto2 at 1:55.082 on his Kalex. Toni Elias was second at 1:55.378 on a Kalex, with Dominque Aegerter third at 1:55.579 on a Suter. Just 19 bikes turned laps.
Wet conditions added almost 12 seconds to the top time of Tuesday, 1:43.365 by Elias.
In Moto3, Australian Miller was the quickest of 20 bikes at 1:57.627 on an FTR Honda. Caretta Technology-RTG teammate John McPhee was second at 1:57.801, with Luis Salom third at 1:57.963 on a KTM.
The quickest time Monday was 1:47.149 by Jonas Folger, who never left his garage Tuesday due to the rain.
Testing concludes Wednesday.
