ABOUT PKRA

Phoenix Kart Racing Association (PKRA) is a non-profit member operated club established in 1982 for those interested in Go Karting.  The club leases property from the Maricopa Park District on which the club maintains an outdoor asphalt track inside the Adobe Dam Park and Recreation Area.  The track allows for multiple configurations of up to 3/4th of a mile in length and averages 25 feet in width. With 12 turns of various radii and over 500 feet of straight away, it’s a constant challenge for both the novice and expert driver.   

The track is primarily for those who own their own karts, though a separate vendor provides an arrive and drive kart rental service (please contact them directly prior to coming to the track to schedule time).  The track is open to the public during regularly scheduled times, but members enjoy reduced rates and voting rights.  PKRA operates under IKF Sprint Kart rules.  See below for required safety equipment and local karting vendors.  

Some are satisfied with the fun of driving during practice sessions.  Others want the thrill of racing, and PKRA organizes club races about every other week, with two seasons of typically 10 races each, with Winter races on Sunday days and Summer races on Saturday nights.  Unlike some indoor karting tracks where every session is a "race" and measurement is by time, these are formal races, with racing officials and results determined by finishing order.  Competitive racing requires more comittment it terms of acheiving proficiency and kart maintenance.  We would like new drivers to acheive lap times sufficient for them not to be lapped in a 10-15 lap race under normal conditions before entering races.

Many maintain their own karts, but local kart shops provide services that range from selling parts to fully maintaining karts, and even to storing and transporting your kart to the track.  

While our focus is certainly karting, Southwest Supermoto regularly holds events at PKRA under a separate Special Use Permit  The schedule can be found on the PKRA Calendar.  More information can be found at the Southwest Supermoto web page http://www.southwestsupermoto.com or the Southwest Supermoto Facebook page https://www.facebook.com/Southwest-Supermoto-219711791390401/.  Specific questions can be directed to:  moto@pkra.com
