Have you ever seen a racer without a transponder at a real track day?
Neither have we - So why charge extra for it, as if you had a choice if you want to strap that box onto your bike? At TrackAttack the transponder is included just as is headwind at 300 km/h.
There's always about € 15 due at the Racetrack for each day. That's € 30 for 2 days and € 45 for 3 days. Here, it's included in the price!!!
