WKA National Enduro Series race at New Jersey Motorsports Park in September 2010, onboard during the Unlimited 2 race. The class uses enduro laydown karts with two 100cc Controlled 2 cycle engines at a minimum of 465 lbs (driver and kart) with centrifugal axle clutches, typical B-Stock class rules. Other karts allowed in this class are 250cc 2 cycle Superkarts (450cc 4 strokes also allowed), 125cc shifters in both laydown and situp style, Formula 125, and similar, so the fastest classes run together. Max speed in this video is 121 mph. Karts with two 125 cc motors are capable of speeds neighboring 150 mph +/- at other faster speedways. The event was a WKA (World Karting Association) kart race held by the Woodbridge Kart Club as their national event at NJMP in 2010. The Lightning Course was used that year. Each engine is mounted on the side near the driver's shoulders. Karting road race events are endurance timed events; this one is 30 minutes in length.
