| USPKS Class Structure Features Two Most Popular Engines in US |
| |
It has not been a big secret that USPKS believes there are too many engines and too many classes in other American based karting series. And it’s not been a secret that USPKS will only feature the Yamaha KT-100S and IAME 125cc Leopard. But until now, the details of the seven USPKS classes have been a closely guarded secret!
USPKS will have seven classes in 2013: four “Yamaha” categories and three “Leopard”. “With fewer classes, everyone will get more track time –much more track time than they’re used to.” states USPKS CEO Mark Coats. “Also, our format makes it possible to own one engine from age 7 to 70 and still race competitively!”
The Yamaha KT-100 classes begin with “Yamaha 100 Rookie” for age 7-10 year old drivers. From there, a steady progression through the 100cc ranks ends in “Yamaha 100 Senior” ~a traditional” class that has proven popular for close to two decades.
“The KT-100 has been the backbone of US karting since the early 1980’s,” continues Coats. “It is still the most popular and most economic 2-cycle karting engine in the world, and with the thousands (if not tens of thousands) of them in the US it makes sense to base the USPKS class structure around this engine package.”
There are three IAME 125cc Leopard categories. “Leopard 125 Semi-Pro” features new karters and those looking to gain experience before moving to the “Pro” level; this class is for ages 14+ and runs with a 25mm header restrictor. “Leopard 125 Masters” pits drivers over age 35 against each other with 30mm header restrictors that will help reduce engine wear and speed (aka save dollars and save “old bodies”). Finally, the series will be headlined with the “Leopard 125 Pro” class for licensed and experienced karters age 16+!
“The Leopard 125 Pro category is for the top professional drivers in the country,” said Coats. “It gives young karters a category to aspire to and a reason to stay in karting!”
All Yamaha categories are limited to one set of tires for the weekend (beginning with qualifying on Saturday). “Tires are one of the leading expenses for any racer,” said Coats. “One of the things we’ve heard from karters is they wanted to reduce that expense and with the Yamaha classes one set of tires will last all weekend and control expenses!”
