With most tracks going full AMA for practice and racing due to insurance the timing couldn't be worse. They won't allow gas and electric at the same time, but there aren't enough e bikes to make a class. Odd bike out. It is commonly blamed on the insurance regulations, without any data to back that up. Pit riding is the problem. Open practice and Open Vet classes was supposed to be where Stark had a home, but that is now being squeezed by the AMA's protectionism.
You certainly have to be aware of your surroundings, not only do you surprise people with no sound, but there's a lot of redneck gas riders hating on e bikes and looking to take them out, and now with the Tesla hate it's getting worse.
Competitive imbalance is the reason the separation started, but it's turned out not to be such a big factor. Still haven't seen any noise making solutions offered as a simple solution. The fire issue isn't ever mentioned anymore. Lot's of interest in tapping into the main battery to run lights and horn.
