Testing began at 10am and concludes at 6pm.

All twelve manufacturer riders are again present for the three-day test, plus the Forward Racing and BQR 'Claiming Rule Teams'.

Factory Ducati rider Nicky Hayden and Tech 3 Yamaha's Andrea Dovizioso will be hoping their healing injuries will allow for greater track time than at the first test, while Karel Abraham (Cardion AB) could struggle with a back injury sustained at the recent private Jerez test.

World champion Casey Stoner - fastest at the first test - was last on track, shortly before 11am.

The second Sepang test finishes on Thursday evening.
