Lowering Revs with sprockets

[Dead Eye]

I'm just going by what is shown on gearing commander - I don't remember what the speeds were on my 600. I think I remember 5900 RPM in 6th being 70mph though and gearing commander says 5600 so its possible someone has made a mistake with it :\

The 1000 gearing is correct though :|

Can any one confirm the correct sprocket ratio just to make sure? It's showing stock as 15F 48R
