Wednesday, 12 April 2017 13:36


For the first time since 2011, the California ProKart Challenge took to the wild and fast Streets of Willow course, hosting the second round of the 2017 championship series. The Rosamond, California facility has been a regular stop on the California PKC schedule, and this time series promoter Tom Kutscher elected to bring something different and exciting. The more than 150 drivers took on the 1.6-mile layout – the largest course in Superkarts! USA competition this season. Four race groups split the time on March 31-April 1, welcoming returning winners and first time victors.
SpringNats Registration Opens Tonight

If the first three races of the Superkarts! USA calendar are any indication, the leading karting organization in the country is primed for another banner year. A motivated 190 drivers invaded Buttonwillow Raceway during the first partially-rainy weekend of February to kick off the California ProKart Challenge, and then the Texas PKC fired up their first pure-SKUSA season with a solid opening round the weekend before the inaugural Pro Tour WinterNationals at NOLA. The California PKC crew was back at it this past weekend on the Streets of Willow with almost 170 entries, proving SKUSA’s success with scheduling races during the first weekend of each month. This consistent spacing now puts the focus on May 5-7, when the Pro Tour continues in Sonoma, California with the eighth annual SpringNationals.

SKUSA is returning to the site of the inaugural Pro Tour event that was held at the Simraceway Performance Karting Center in Sonoma in 2010. Held over a mid-April weekend seven years ago, a total of 98 entries took part in this first event, which ushered in a new era for the organization’s championship program. Over the next seven years, the SKUSA Pro Tour has developed into the leading national championship series in North America, with entries for this year’s SpringNationals projected to eclipse the 250-driver mark. Per Tom Kutscher, SKUSA CEO, “Talking to a number of team managers already, I wouldn’t be surprised if we hit 300 entries for this event, with multiple classes selling out at the 40-entry cap right away.”
