I race an indoor spec class on road, and it costs more, you have to keep on top of your motor and batteries.
I race off road and have had the same motor batteries and speedos for the last 3 hears, simply because I have more power than grip. The moment you have more grip than power is when things start getting pushed to the limit.
I would think the reason its not used is because no one has been the the agm with a good proposal or no one wanted it.
