STI and Yamaha have partnered up for one of the key racing series in the southwestern U.S. – the 2013 Yamaha Quad-X Racing Series Presented By STI.

STI Trackside Support

Now in its 11th year, the series gets underway this coming weekend at Glen Helen Raceway near San Bernardino, Calif. The Quad-X Series will continue for seven more events throughout the Southern California and Arizona region during the year and reach its conclusion back at Glen Helen for Round 8 in early November.

STI will once again be a prominent part of the Quad-X series as competitors can rely on STI’s trackside support program, which is run by Big Kid Racing.

Big news this season is the addition of an STI Tire & Wheel race contingency program. Mount STI Tech 4 MX tires front and rear, then get signed up and checked off through Big Kid Racing. Strong performances will be rewarded with credits towards more STI products at future events.
