Scott Redding admitted he was feeling the strains of a long season as he wrapped up two days of private MotoGP testing at Jerez in Spain.

Redding, who will ride a Ducati GP16 next season for the Pramac team after team-mate Danilo Petrucci prevailed in their personal points battle to earn the team's sole GP17 ride, said he was feeling slightly frustrated after struggling to match the times of fellow Ducati riders Karel Abraham (Aspar), Loris Baz (Avintia), Hector Barbera (Avintia) and Alvaro Bautista (Aspar).

"I kind of hit a brick wall today and we couldn't improve the lap time. Towards the end of the day we found something with the mapping, which helped me quite a lot, but I was just too physically tired. I'll be fresh for next year's test to start where we left off," Redding said.

"I was quite surprised by some of the lap times today, with [Alvaro] Bautista doing a '38.9 I think it was, which is pretty fast. I don't know if it's just this track and winter time and sometimes people get a good feeling, but all of last year's bikes seem quite fast here.

"To be honest it's not been too great and there's no winglets on the bike, so I don't really get a true comparison. We're losing a lot of time compared to last year in the straights but I'm surprised by the lap times of the guys. Abraham, coming back, not a bad lap time, and Baz, Barbera and Bautista are all fast. I'm not too sure if it's just this track at this time of year," he added.

"When I look back at last year I beat those guys most of the year round but now they're nearly a second faster than me."

Redding, though, said he wouldn't push the panic button just yet and added that he is looking forward to a well-earned break ahead of his next test in 2017.

"It's too early to be worried about it. There's a lot of potential to come with the bike. Danilo, having a new bike with the winglets, was nothing really special. With last year's bike going nearly a second faster, I think he's more worried than I am right now," he said.

"We have to see when we start testing again next year. I don't feel bad with the bike but sometimes the lap time isn't flowing and I'm not sure if that's because I don't have the winglets or what. We do need to have a look through the data but we also seem to be lacking a bit of corner speed at the minute too."

The British rider has decided against completing a third day at Jerez, preferring instead to wait until 2017 to use the remainder of his testing allocation.

"We had the option of three days but we decided to do two days. We're only allowed five test days so we didn't want to burn them all up. I just want to chill out, sleep on the sofa and then start doing a few things. I generally feel quite tired and towards the end of the season there was quite a lot of pressure and that takes it out of you," he said.

"I just feel a bit tired after the whole race weekend and then testing and more testing. I just want to go home! It was a long season but it's done now and I can get back and rest."

Redding was 12th fastest on Thursday with a lap in 1m 39.985s, with leading MotoGP Ducati rider Bautista over a second faster on the Aspar machine.
