WEM confirms format structure of 2012 MX Nationals series Williams Event Management (WEM) has announced the formats that competitors will contest during the 2012 MX Nationals , Australian Motocross Championship. WEM has continued to create and evolve custom formats specific to the national series, introducing formats that will feature a blend of traditional motos around 30 minutes in length, as well as a mix of spectacular shorter, back-to-back races. "Everybody has different opinions on formats, some are very traditional and others like the fast-paced shorter format," WEM boss Kevin Williams explained. "I think the compromise we have come up with will be a win-win for all. We are very excited about the 2012 championship and I believe that we have the best rider line-up ever, so it's going to be one season not to miss." The formats of the MX Nationals, Australian Motocross Championship, will be structured by the number of laps for each race, rather than timed to a certain length in 2012. 2012 MX Nationals, Australian Motocross Championship, Event Formats: Pro Open* 2 x 10-lap motos back-to-back and 1 x 16-lap moto (three motos per round) Pro Lites* 2 x 7-lap motos back-to-back and 1 x 14-lap moto (three motos per round) Under 19s* 2 x 6-lap motos back-to-back and 1 x 10-lap moto (three motos per round) Vets 30 to 39 4 x 7-lap motos Vets 40 Plus 4 x 6-lap motos Support Classes** 3 x 7-lap motos Pro ATV 4 x 7-lap motos * Round two (Coonabarabran) will be adjusted, according to the longer track length ** Subject to change at the promoter's discretion, with approval of the Clerk of Course
