Hello everyone. Can anyone explain to me what short gear ratio is? And I would like to know if there is a way to eliminate the first gear in our car. Currently the gear is 1-N-2-3-4-5. So I would like to eliminate the 1st gear so that it’ll be N-1-2-3-4 @ N-2-3-4-5. We’re using Honda CBR 600 F4i.

well if you plan to do so (our team did it years ago) you'll have a insanely big rear sprocket that is almost a 5th wheel.
you'll need almost 30% more theet on that sprocket if you want to mantain the same driveline ratio
I don't have the details of how to modify the gearbox to do so, but.. the big sprocket is already an issue.

We run a twelve tooth front and a 55 toth rear on a stock f4i. first gear is pretty much useless. its kind of just there if you really bog out in a corner and need to get your revs back up.
