Yep, it comes with a 34-57 primary and 28-68 final.

You can install a 38 from the Brazil/Japan bikes in the primary.

And, can go to a 29-68 or 30-66 final.

But unless you do some engine work, you wont be able to pull the higher gearing at high speed.

A good tune and exhaust, along with taller gearing and a raised redline, will get you significantly faster than stock. It may not pull all the way to the new redline, but it will easily get you another 10+ mph.

Roger that.

Stock, you have more speed than you can use on the street.

With a 38 in the primary you have as much as you can pull on most tracks.

And the race series geared up the final for Daytona, but unless you are running there or the salt flats, you'll never use that much gear.
