Tim, not so much a load of crap. It pretty much happens that way in every “spec” class. That’s why so many good ideas for “equalizer” classes, (Yamaha, moto, ICC, stock moto, TaG) soon turn out to be the most expensive class to run. It’s simply the natural progression.
Again, the beauty of KZ is you get what you pay for. If you want to go faster pay more money
Also note that KZ internationally (outside North America) use super soft tires in championship races. A KZ race on the international scene is an awesome race to watch.
