Tech3 Yamaha's James Toseland is frustrated with his Friday practice performance at the Sepang MotoGP round in Malaysia, saying he is struggling with corner exit speed.

The two-times World Superbike Champion finished 13th in today's free training session and is more than a second slower than team-mate Colin Edwards, who was quickest.

“This track is so long and technical that it took a bit of time to get back into the swing of things and the test in January seemed like a long time ago," said the Yorkshireman.

"I felt pretty comfortable this morning but we never really moved forward with the setting this afternoon and that is a bit frustrating. We have got an idea on how to improve the bike for tomorrow because I’m struggling on corner exit. When I’m mid-corner and getting on the throttle, I’m struggling with some feel from the rear to get off the corner.

"At a track like this where there are a few bumps it is making it feel as twice as bad. There are also a lot of corners where you accelerate from slow speed, so rear feeling is crucial. I can do high 2.03s and I’m about three-quarters-of-a-second off the best race pace, so it has not been a disastrous day.”
