Miguel Oliveira made more gains on Sunday despite bad weather forcing the cancellation of the third and final Moto2 session in Qatar.
The Portuguese rider was second fastest on Sunday behind Franco Morbidelli on the new KTM chassis and fifth quickest on the combined times from the final three-day winter test at the Losail International Circuit on the Red Bull KTM.
“These nights of testing have been very positive. Above all, we have changed some things on the bike from yesterday to today that have given me a lot of confidence to progress,” he said.
“The times do not show that the conditions were not the best, nor do they show the work we have done, but I'm happy with how the evening went. Hopefully next week the weather will be more stable than during these three nights.
“From the times in testing it is a bit difficult to say who will be up at the front next weekend at the race, but we are on the right track to be one of the outstanding riders.”
Rookie Brad Binder, who dominated the Moto3 class to win the world title in 2016, was 21st fastest overall on the second of the Red Bull KTM machines and is happy with his progress as he prepares for his race debut in Qatar next weekend.
“Today went very well. At first it was a bit tough, but little by little I found my way, every time I get on the bike I'm learning something new and it makes everything a little easier for me,” he said.
“We have to continue working in this way. It's a shame to have lost a whole day and part of today, because it was too windy, but all-in-all, I feel we have taken a step forward this weekend. I feel much better about the bike; next week we will try to keep taking steps forward every day.”
