UNITED STATES PRO KART SERIES CLASS STRUCTURE ANNOUNCED

1/22/2014

"Defined ladder from Rookie to Pro"

Article By: Race Tech Development

January 22, 2014 - As the United States Pro Kart Series (USPKS) enters its sophomore season, the series continues to evolve and provide a solid structure for national level racing. Poised and ready to take 2014 by storm, the USPKS program has put in place a defined ladder of classes from Yamaha Rookie to Leopard Pro.

"I am very pleased with the class structure that we have in place for 2014," expressed series owner Mark Coats. "We have put in place a defined ladder from the rookie division to the pro classes. For followers outside of karting, they can see this defined ladder and it will be easier for them to follow and get into the sport of karting."

Beginning at the bottom and working the way up the ladder, the Yamaha divisions will be apparent, as the USPKS will run Yamaha 100 Rookie, Yamaha 100 Cadet, Yamaha 100 Junior and Yamaha 100 Pro. All classes will qualify on new tires and must use the same tires for the entire event weekend. While the Yamaha Rookie and Yamaha Cadet classes will utilize the MG HZ (Red) tire, the Yamaha Junior and Yamaha Pro ranks will run the much softer and quicker MG FZ (Yellow) tire.

Moving to the TaG divisions, there will be four different classes beginning with the Mini-Rok 60 Cadet class for 8-12 year old competitors.

"We are happy to have a premier series in the Midwest add the Mini Rok class to their program," expressed OTK USA's Andre Martins. "There is great participation at other series across the United States and I am confident that Mark and the USPKS program can build the class throughout this part of the country. Mark has a great program and brilliant ideas for the future and Vortex is happy to be part of it."

From there, drivers can make the transition to the Leopard powerplants to compete in Leopard 125 Junior, Leopard 125 Pro and the Parilla 125 Challenge for drivers over the age of 30. While the Leopard 125 Junior and Leopard 125 Pro will utilize only IAME Leopard engine packages, the Parilla 125 Challenge division will allows the use of both the Leopard and X30 engines.

Coats added, "We are not allowing the X30 engine in the Junior or Pro ranks in 2014 but are reviewing it for the 2015 season. The disparity and speed differential between the engines will raise the cost of karting and we want to provide an equal and level playing field for a national campaign, and not make it about who has the most money for the right engine package."

The Leopard 125 Pro class will utilize the MG FZ (Yellow) tire compound and will be required to have a new set of tires for both event days. The Leopard 125 Junior class will qualify on new tires on Saturday and be required to use the same tires throughout the event weekend while Parilla 125 Challenge competitors will be required to qualify on new tires, and will have a total of six to use throughout the event.

"To help grow the Parilla 125 Challenge divisions, we are allowing drivers from 16 years of age and up. 16 - 29 year old non-pro competitors may compete in the class as determined by USPKS. Also, to decrease costs, any driver in the Parilla 125 Challenge division will have to declare their engine of choice and utilize that for the 2014 USPKS season," continued Coats.
