Superkarts! USA Readies for MothersĀ® SummerNationals
Friday, 08 July 2011 08:57
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.”

Friday, 10 June 2011 09:49
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.”

Wow!  What a track, what a race!  We had some stacked fields in most of the classes, although the competition was fierce in ALL classes... well except for TaG Cadet where Colton Herta took P1 in all 4 heats and both mains.  So it comes as no surprise that his motor was claimed by another competitor.  EKN was on site doing a live broadcast of the race call, alongside my live timing feed for the people who couldn't be there.  They've also written complete recaps of each day. (Saturday, Sunday)  For stunning visuals make sure to check out the photos (Friday, Saturday, Sunday) provided by Todd McCall of On Track Promotions.  And finally, a special thanks to SKUSA's own Ken Schilling, for his work on the Championship Points.  Bench racers and beyond can find complete MyLaps results for Round 1 and Round 2Hope to see you all at the Streets of Willow next weekend, and stay tuned for more exciting announcements!
