Jerrod, start work a stock class bike, it's the easiest and cheapest way to get started. Then if you love the track riding build something fast.
I started with a day Moby, but my favorite is my stock bike. I'm almost as fast on it as the kitted Moby (within 2 seconds lap times)
Come out to GP Midwest this year for sure, everyone is welcome, and being a serious racer isn't necessary!
