Scott Redding heads to the final round of the Moto2 season with a career-best fifth in the World Championship already secure.

But the Marc VDS rider won't be backing off, since he still has a mathematical chance of snatching fourth place from Thomas Luthi.

Redding, who has taken four podiums this year, is 16-points behind the Swiss rider.

"This season has been a positive one for us, but it's not over yet," said the British teenager. "My fifth place in the championship is secure, but there's still an outside chance of nicking fourth from Tom L?thi. So, for me, there is nothing to lose this weekend, which means I can go all out for the podium.

"The battle for the championship between Marc Marquez and Pol Espargaro is finished, but both of them will be looking to win in front of their home crowd this weekend, which means they can't be discounted.

"But, if I can qualify up near the front and then get away with the leaders from the start of the race, then I'm quite happy to push to the limit - and beyond if necessary - to get on the podium.

"That's all I can do; I can't influence Tom's race, so we'll just have to see where we are championship wise after the chequered flag."

Redding will remain on a Marc VDS Kalex for 2013, as will team-mate Mika Kallio.

Kallio secured his best result of the season with second at Valencia last year and has won at the circuit in both the 125cc and 250cc classes. The Finn, who hasn't scored in the last two races, is sixth in the standings, 11 points ahead of Tech 3's Bradley Smith.

"The overseas races were hard. I was able to run the same pace as the top five but, unfortunately, I didn't manage to collect many points," said Kallio. "It means that I go into the final race having to defend my sixth position in the championship, rather than pushing to take fifth from Scott.

"But I'm not thinking about the championship, only about the final race. I want to finish the season with a good result, at a track on which I've won before and where I took my first Moto2 podium last year.

"I'm pretty confident going into the weekend but, as we saw in Australia, anything can happen in Moto2, so hopefully we'll have luck on our side as well for the final race of the season."
