I think a lot (maybe 6 or 7) of the e-racers from 2013-2016 purchased Brammo's and raced them, and I bet several are now upgrading to Energica's or SR/S or SR/F's. Creating these other classes might improve the market for those used bikes to keep the grids populated, and also lets people who have the lower powered bikes know they are still welcome to come out and race, and get a discounted entry fee too. I have raced with several organizations including AHRMA, and AHRMA was probably the most expensive race entry fees, and had the most strict (and expensive) qualification criteria and membership costs. They also ran the most professional and organized events that I have competed in, the cost is worth it. Giving a discount to people who want to race these bikes against each other, but aren't really competitive against the higher power models is a really nice gesture. To give some background, AHRMA runs multiple classes on the track at the same time (gas bikes, and electric bikes), so there is always someone to race with. I am pretty sure they are just going to grid all the electrics together on the track ad the same time, with several other gas bike classes too, basically if you have a Brammo, or a lower powered Zero, you will get on the grid with all the electrics, you just get a discount on entry fee and won't earn points towards a "championship" .
