Humm pretty hard to tell I think, depends on your set up. I have an 05 Screaming Eagle Fatboy. Each gear at 2000 rpm is 10 mph. 2000rpm@3 gear=30mph; @4gear=40mph; @5 gear=50mph. I don't know tranny ratios or belt ratios but that is what my bike runs in stock form.

You should be running about three grand at 80

two grand at fifty.

So twenty five at 65.

Hope this helps,

David
