The MotoGP season starts again this weekend in Qatar, but there is plenty of action to look forward to outside the top class.
With 66 riders from 18 countries - spanning five continents - in the Moto2 and Moto3 classes this year, the competition is set to be as tough as ever.
Ask any Moto2 rider who they think the favourites are and a long list of probables comes up: Thomas Luthi, Pol Espargaro, Andrea Iannone, Julian Simon, Claudio Corti, Toni Elias, Alex de Angelis, Bradley Smith and Scott Redding among them.
But the one name that really stands out is that of last year's runner-up, with seven wins and a further four podiums, Marc Marquez.
What is Moto3?
Moto3 is the new lowest cylinder class, replacing the two-stroke 125cc bikes with four-stroke 250cc ones.
It was brought in to keep the prototypes more relevant to the motorcycle industry.
The 12,000 euro (£9,900) price cap on engines and single spec ECU (Dell'Orto) and tyres (Dunlop) has been introduced to keep costs down and create more competitive racing.
It says a lot about the Spaniard that while still on an extended recovery from the vision problems sustained
in a crash in October,
he was already being touted as the favourite for the title this year.
At the last official test in Jerez, Marquez posted a top-five time on each of the three days to dispel any suspicion that the former 125cc champion might start the season off the pace.
It is as clear now as it was at the end of last year: Marquez is the man to beat in 2012.
For British rider Redding, a 2011 season without a podium, after a promising display in his debut year, was little short of a disaster but renewed confidence this year should see a revitalised performance from the 19-year-old.
One of the tallest riders in Moto2 at just over 6ft - and still growing - Redding needs to get on a bigger bike and soon, and has the extra incentive of knowing that he is in the shop window for a 2013 MotoGP ride.
