"The track has been completely revamped since then too, with extra jump sections added.
"The soil has been groomed, ripped and watered and we are expected some very high-class racing."
It is perhaps not hard to pick a favourite to win the 14 to 16 years' 250cc class this season because it's hard to look too far beyond Amberley's Micah McGoldrick. Although McGoldrick is only 16, he ran away with the 125cc title in the four-round senior motocross nationals which wrapped up at Taupo last month, and also claiming the under-21 title, so his form at the moment is very hot indeed. McGoldrick won the 13 to 16 years' 85cc class at the junior nationals in 2010 and won the 15-16 years' 125cc class last season.
But there are a handful of riders capable of matching McGoldrick, including Rotorua's Cameron Vaughan, the young man who finished runner-up to McGoldrick at the senior nationals, Wellington's Josh Bartosh, and Josh May, of Timaru, and Cody Scott, of Geraldine.
In the 15 to 16 years 125cc class the battle should be fierce between riders such as Katikati's Garth Amrein, Atiamuri's Hadleigh Knight, Kumeu's Chase Smith and Pahiatua's Scott Sowry.
In the 12 to 14 years' 125cc class, look out for Levin's Billy Frank, Taupo's Cohen Chase, Temuka's Harrison Sayer, and Australian visitor Jordan Hill.
Other Australian riders - including Hunter Lawrence, Blake Cobbin and Tyler Darby - add international strength to the 85cc categories, with racing tipped to be especially tight in the 11 to 12 years age group with Kiwi hot-shots Maximus Purvis, of Mangakino, Silverdale's Claude Griffith and Nelson's Reece Walker expected to feature.
The national championships have five races in all seven separate age group and bike capacity classes.
