The X2 transponder is the latest generation of MyLaps race proven transponders. The X2 transponder offers two-way communication between the scoring system and the vehicle. This transponder is backwards compatible with all MyLaps decoder boxes.
This transponder comes with a 2-year subscription. Your transponder is covered by a full factory warranty for the duration of the subscription.

NOTE: This transponder will ONLY work in MX (motocross) applications, or where your race director has specifically stated that they use MX (orange) transponders.
