EKN Trackside: SKUSA Pro Tour MothersĀ® SummerNationals - Preview

The second event of the Superkarts! USA Pro Tour takes place this weekend in Grand Junction, Colorado with the sophomore edition of the Mothers® SummerNationals. The 9/10-mile circuit of Grand Junction Motor Speedway will host the event, providing a stunning backdrop and racecourse for three days of exciting action to complete Rounds 3 and 4 of the five-race championship.

The Honda Racing/HPD SpringNationals kicked off the Pro Tour in late April/early May at the Musselman Honda Circuit in Tucson, Arizona. Aside from the occasional wind/dust storm, the weekend was a triumph with 164 drivers contesting eight categories, an increase of 70% from the inaugural event in 2010. With 130 drivers entered prior to arriving in Grand Junction for the Mothers® SummerNationals, the event could see an increase of more than 50% from last year’s event in Wisconsin.

The Grand Junction Motor Speedway is among the best karting circuit designs in the United States. At just under 1-mile, the 32’ wide course offers a variety of fast straightaways, technical corners and elevation changes. A view of a hot lap from TaG Senior driver Martin Plowman during testing can be viewed HERE

The SKUSA Pro Tour, in just its second year, is gaining a lot of attention thanks to its straight-forward format of Stock Moto shifterkarts and tiered TaG classes. The internal ladder system in Stock Moto - S1, S2, S4, S5 - and through the TaG divisions - Senior, Master, Junior, Cadet - allows competitors to begin their karting career with the organization at any level and graduate up the ranks based on age and experience. The list of drivers taking part in the program continues to grow and, in accordance, the prestige of a Pro Tour championship is increasing as the participation numbers and level of competition increases.

The eight entry lists for this weekend’s Mothers® SummerNationals are loaded with talent, ready to tackle the Grand Junction facility and continue their chase to Pro Tour championship glory.  Read the FULL story at

Superkarts! USA Readies for MothersĀ® SummerNationals
Friday, 08 July 2011 07:57
The much-anticipated second round of the 2011 Superkarts! USA Pro Tour is now just one week away as the Mothers® SummerNationals will be held at the Grand Junction Motor Speedway on July 15-17. A projected list of 150 racers will compete for three days in two full rounds of racing, which will count toward the season championship that began just two months ago in Arizona at the Honda Racing/HPD SpringNationals. Eight categories will continue their attack on the Pro Tour championship, with the headline categories of TaG Senior and S1 Pro Stock Moto vying for a portion of the $3,500 purse.

“I can’t believe the Mothers® SummerNationals is already here,” commented Superkarts! USA President Tom Kutscher. “It seems like yesterday we were setting up in Tucson for what was an exciting weekend to kick off the 2011 SKUSA Pro Tour. I’m happy to be returning to Grand Junction after being there to start our rejuvenated SKUSA Mountain Region two weeks ago. Our Pro Tour racers are going to love this place. Those drivers who still have not registered have until this Sunday, July 10 at midnight to sign up and qualify for the pre-entry pricing. Anyone who is on the fence needs to just commit to it. You won’t be disappointed with what we at SKUSA, the competitors, and the track in Grand Junction have to offer.”
MothersĀ® Signs as SKUSA SummerNationals Title Sponsor
Friday, 10 June 2011 08:49
Superkarts! USA is pleased to announce that they will partner with Mothers® Polishes-Waxes-Cleaners for the upcoming stop on the national karting schedule. Mothers® has signed on to become the title sponsor of the second event of the 2011 Superkarts! USA Pro Tour – now labeled as the Mothers® SummerNationals. The event will be held at the Grand Junction Motor Speedway in Grand Junction, Colorado on the July 15-17 weekend, with an expected 200 drivers competing in the shifterkart and TaG divisions. Mothers® will be out in force, supporting the racers with prize packages for each and every podium finisher.

“Mothers has been a valued supporter of SKUSA ever since I’ve been at the helm, and we couldn’t be happier to continue this strong relationship,” stated Tom Kutscher, Superkarts! USA president. “Their products are superior and the relationship they have with motorsports, especially the grassroots level, is phenomenal. We are extremely pleased to have a company like Mothers as part of the SummerNationals this year. There is no doubt this event will be one step above what we did in Tucson for the SpringNationals, and that’s saying something. I can’t wait.”
