EKN Trackside: Superkarts! USA Pro Tour SpringNationals - Paddock Pass
Tuesday, 16 April 2013 09:26
The 2013 Superkarts! USA Pro Tour kicked off the season today as the SpringNationals officially began with a full day of practice at the Musselman Honda Circuit in Tucson, Arizona. A record number of entries (227) packed the paddock, leaving little to no room for any more trailers or spots to pit in. Weather was fair, as those who live in the cold weather enjoyed the 80 degrees temperatures and the clouds kept the direct sunshine off the many family members and mechanics lining the fences throughout the day. Below are some notes from in and around the event to set the stage for the weekend. Read Full Story on EkartingNews.com
 
Important announcement regarding Mini ROK pistons
Wednesday, 10 April 2013 11:29
Attention: TaG Cadet Competitors, Kart Shops and Engine Builders:

As many of you know, Vortex has experienced a shortage of pistons for this engine. While they are working hard to remedy the situation, it has created a current hardship for some.

SKUSA has agreed to allow the use of the IAME Swift piston in this engine as a temporary solution to the problem. If used, it is important for the competitor to advise the event technical staff of its use in a specific engine prior to qualifying.

When the supply problem is corrected, sufficient notice will be given as to when the Swift piston is no longer allowed.

NOTE: A limited supply of Swift pistons are expected to be available at the SKUSA Pro Tour Springnats in Tucson this weekend.

Record Attendance Confirmed for Superkarts! USA Pro Tour SpringNationals
Sunday, 07 April 2013 08:14
The 2013 Superkarts! USA Pro Tour is expected to be bigger and badder than ever before. Entering its fourth season, the three-event program has been enhanced by its largest series prize package ever -- now set at roughly $96,000 for the year. A sign of the series’ strength and popularity, the Pro Tour has enjoyed an increase in participation year-after-year and has attained record numbers each season. This year’s SpringNationals, which is set for April 12-14 at the Musselman Honda Circuit in Tucson, Arizona, is welcoming yet another record-setting number of drivers, as a total of 197 pre-entries have been processed so far and verbal commitments have well surpassed the 200 mark.

The SKUSA Pro Tour has experienced steady growth over the previous two seasons following its debut in 2010. The majority of classes have already surpassed last year’s numbers, highlighted by the strongest increase in the S2 Semi-Pro Stock Moto, TaG Master and TaG Cadet classes. SKUSA shifterkart racing is continuing to expand – and the cool-factor has increased – as many of the young guns in the sport are working their way up the ranks and into the headline S1 Pro Stock Moto class. The continuing graduation of S2 front-runners means that there is an exciting number of young pilots stepping up to become the next rising star in Superkarts! USA action.
