Moving in line with the MotoGP world, the Expert class is now called GNC1 and the Pro (support) class is GNC2.
Here's all the info from the AMA... (ET is Eastern time (New York time) if you're trying to work it out from anywhere else in the world)
On-track action begins both days with practice sessions at 3:30 p.m. ET (12:30 p.m. PT). The pre-race show is slated for 6:15 p.m. ET (3:15 p.m PT) to 7:15 p.m. ET (4:15 p.m. PT) and opening ceremonies are scheduled for 7:30 p.m. ET (4:30 p.m. PT). The GNC2 main is set for a 9:40 p.m. ET (6:40 p.m. PT) start with the Bruce Rossmeyer's Daytona Harley-Davidson GNC1 main slated to see the green flag at 10:10 p.m. ET (7:10 p.m. PT).
Every session from the "World Center of Racing" will be streamed live for fans around the world at FansChoice.tv.
Jared Mees will begin his GNC1 title defense, sporting the No. 1 plate for the third time in his career, but he'll be facing off against the likes of Bryan Smith - last year's runner-up for the GNC1 title - Brad Baker, Kenny Coolbeth, Jr., Jake Johnson and the rest of the star-studded field.
In 2014, Briar Bauman and Coolbeth kicked their seasons off on the right note. Bauman took the first checkered flag on opening night with Coolbeth putting on a clinic in Round 2 to earn the victory.
In the GNC2 class, Ryan Wells and Brandon Wilhelm left Daytona Beach with victories to start the season.
Kyle Johnson, the 2014 GNC2 champion, and Jarod Vanderkooi, winner of four GNC2 races last year, highlight a rookie class moving up the elite ranks to challenge Mees, Smith, Johnson and the others.
The GNC1 lineup is full of potential winners. Sammy Halbert, Johnny Lewis, Mikey Rush and Brandon Robinson have all won main events at DAYTONA Flat Track since the new circuit debuted in 2010, and none can be counted out in 2015.
DAYTONA Flat Track will also play host to, for the first time in AMA Pro Flat Track in history, a brother and sister racing with National Numbers. Shayna Texter will debut her new No. 52 and join her brother, Cory Texter, owner of No. 65.
Baker, the 2013 Grand National Champion, will be back in the saddle after suffering a shoulder injury at the Superprestigio exhibition race in Barcelona, Spain, in December. His status has been the subject of speculation recently, but the Factory Harley-Davidson rider has confirmed he'll be in the field Thursday.
Jared Mees' wife, Nichole Mees, will not be in the field at Daytona, but plans to run other races in 2015, which she said will be her final season.
The entry list also has plenty of international flair with Doug Lawrence and Michael LaBella representing Canada in the GNC1 ranks and Italian Vittorio Marzotto and England's [the DTRA's!] Alan Birtwistle racing in GNC2.
