Marc Marquez officially presented his 2012 Repsol-Suter Moto2 bike in Barcelona on Tuesday.
This season will be the 2010 125cc world champion and reigning Moto2 runner-up's fifth in grand prix, but he has missed most of winter testing due to double-vision problems following the Sepang fall that ended his 2011 title hopes.
Prior to that accident Marquez had mounted one of the most spectacular fightbacks in grand prix history. After failing to score a point in the first three rounds, Marquez claimed more wins than any other rider (seven) and took the title lead at round 14.
Marquez then charged from last to third after a grid penalty for causing a big practice accident in Australia. But his following Malaysian fall - caused by an unmarked wet section of track - ruled him out of the last two rounds and ended his rookie title hopes.
Sidelined for five months due to vision problems, Marquez was fifth fastest during the final pre-season Moto2 test at Jerez.
"I missed a large part of the pre-season and obviously I am lacking a few more kilometres on the clock for the opening race. However, getting to the last test of the preseason at Jerez with my eyesight 100% recovered was very important,” said Marquez.
“We did a good job at the test, I regained confidence on the bike and it was good practice for the entire team. Now we just have to see what happens in Qatar.
“We aren't completely prepared because some of our rivals are still a step ahead, but that just means that at the first few races we will have to focus on our own job and have patience. Then we'll see if we can show the kind of form that we had in the latter stages of last season.
“One of our goals for this year is to fight for the Moto2 title and we will give everything that we have to achieve this, although I prefer to go race-by-race and not think too much about the Championship".
The Qatar Grand Prix night race will take place on the evening of April 8.
