Well I think I've slowed down a lot on the road since I've been riding more on the track - especially after starting racing.
But then I noticed my speedo telling me that it might just be that I'm more comfortable with braking hard, the handling of the bike and generally just carrying more speed etc?
So I don't know really. I do think I'm a lot safer on the road than I was. But then that's not hard, I'm surprised I'm still alive!
