The NMA Grand National Motocross Championships in Ponca City, Oklahoma, came to a close on Saturday, July 31, after nearly a week of racing. Attendance this year was way up over last year, with the NMA reporting a record number of entries that reached the 2300 mark.There were many multiple class champions this year, which included one who was arguably the fastest rider of the week - Jason Anderson. The Kawasaki rider who hails from Bernalillo, New Mexico, won three Pro-class championships and nearly made it four had it not been for a crash in the 250cc Modified Pro class. Anderson made up for that one loss by scoring overall wins in the 450 Stock and Modified, and 250 Stock Pro classes.Suzuki rider Ian Trettel took home the number-one trophy in the 250cc Modified Pro class.Adam Cianciarulo was, once again, the fastest rider in the mini ranks. The Kawasaki rider from Port Orange, Florida, was unbeatable in the 85/150 Modified (12-13) and Supermini Thru 13 and Thru 16 classes.Another hot minicycle racer was Honda-mounted Cooper Webb from Newport, North Carolina. Webb left Ponca City with four class championships title under his belt, including the 85/150 Stock and Modified (14-16) divisions, 85/150 Open Thru 16, and 150 Four-Stroke Thru 16 classes.Lance Kobusch, from New Florence, Missouri, turned a lot of heads in the small-bore ranks. Somewhat unexpectedly, the Cobra-mounted rider came away with three class championships, two of them in the P/W Stock (4-6) and (7-8) classes, and one in the 65cc Jr. Cycle Modified (6-8) class.Other multi-class champions in the small-bike category included Luke Purther and Mark Worth. Purther topped the 65cc Jr. Cycle Modified (9-11) and 65cc Jr. Cycle Open Thru 11 classes, while Worth topped the 85cc Stock and Modified Thru 11 classes.Oklahoma's own Justin Bogle also left Ponca with a lot of gold hardware in his hands. The Kawasaki rider came away with four class championships in the 250 Stock and Modified and 450 Stock Intermediates classes, and in the 125/250 Schoolboy Thru 17 Non-Pro class.
