All participants will need a transponder. We strongly suggest purchasing (at cost) as we have a very limited supply for rental. Availability will be shown at checkout. This system is more accurate and is currently used in MotoGP and MotoAmerica and now here.
Mylaps X2 transponders are subscription base and allow live timing to be viewed on their app and website.
Transponders are available from MyLaps https://speedhiveshop.mylaps.com/ and other sources.
