I don't think they're having the pitbike races at the AMA nationals anymore. That series got cancelled. There are some new pitbike classes & rules for the Arenacross series. Look at: racearenacross.com

They are definetly still having the pitbike nats next year Rob Budyos is in charge of them and he said they are going to initiate a few updates next year so it is definetly on.

The classes are way to broad. Not really a class for just a 88cc bike if you have mods, you basically get smoked by a 126cc bike. I guess its all or nothing with your engine. sorry just my opinion

 

Remember its a "side show" to the nationals and they cant fit in everybody. I see no problem with a stock class and a open class. I raced high point and steel city last year and its a blast, always a bunch of drunk weekend campers loving the mini races.

 

You tell them R Free! Im racing both hope to c-ya there.
