I'm still sorting out my NC30 at the moment, so I took my modified KR1 instead, and my friend was on her modified FZ750.
I installed an action cam behind the headlight aperture and got some quite good clear footage of the big bikes getting in my way. Its a shame there aren't more 400 and 250's at track days though

I got footage of 6 20 minute sessions, but have included a link to a 5 min clip here;
