When it comes to racing kart timing and scoring, look no further than the MyLaps training transponder to get accurate, repeatable, and reliable information for your motorsports competition. Nationwide, almost all kart racing facilities utilize an automated or non-analog timing/scoring system, with the MyLaps TR2 system being the latest and most commonly used system at motorsports facilities across the United States. For most sanctioned competitions, the use of a digital transponder like the MyLaps TR-2, X-2 transponder, or TranX 160 is mandatory and expected for all competitors. While a series might rent one, most charge a fee, and most racers prefer to have their own. Look below through our MyLaps products to find which one is right for you. Do you have any questions?
