I bought my leathers a couple weeks ago. It's a two-piece Alpinestars Carver suit that has a hump, so I hope it wouldn't be illegal if I pull the front fairings off the Ninja to run Modified. On page 74 it states "Forward of the rider is defined as any area from the most forward edge of the motorcycle to the silhouette of the rider as viewed from the side, excluding the hands and arms." With the hump being on the back of the silhouette, I interpreted it to be ok for the Modified and Altered classes. I could be wrong though, it wouldn't the first time and certainly not the last!
