14 tooth front sprocket and 60 tooth rear sprocket on a 01 f4i roughly top speed Any help would be great thinking bout going to a 60 but drive bike to lot. And drive for about 15 mins on a highway doing 60

Just went stock front 60 back, run 60 at about 9 grand. Imo its a little much for the highway. whats on it now. if stock go 55-56 that will be a little better on your bike.

Towlieee

my f4i has a 60t, and I'm at around 8.5k rpm at 80mph

I travel on the highway all the time with it

throw some nitrous on it for the highways

0 chance your going 146 with that setup thats only 10 mph slower than stock. To the original poster that's a pretty aggressive setup to ride on the street, I used to ride 14/52 and it was alright for street, still pretty annoying on the highway though.
