4. Moto2 And Moto3 May Steal The Show
It could be argued that there were a few rounds last year where the support classes were more exciting to watch than the MotoGP boys. This year, with 33 Moto2 riders and only one less in Moto3, all of whom do not fear of banging bars, the excitement on track promises to be just as, if not more, exciting than ever.
In Moto2 the field is wide open, as 2012 champ Marc Marquez moves up to MotoGP. However, Pol Espargaro has to be considered the favorite this year as he was the only rider who could even remotely keep Marquez in sight last season. Look for a number of threats though, like 2011 125cc champ Nico Terol, who seems to have adapted to a four-stroke racer.
Moto3 action should be equally exciting; with 2012 title winner Sandro Cortese in Moto2, the championship is up for grabs. Riders to watch include Romano Fenati, Zulfahmi Khairuddin and Maverick Vinales, who switches from Honda to KTM machinery this year.
