Gen I. Sprockets ratio for The Track?

[geecare]

Looking for the best ratio combo for the twisties and the track, any suggestions? 16/42-43 seems to be the only ratio found so far on the org.

Depending on the track, I'll run 16/42, 16/40, or 18/42. Out on the street, I run 18/40.

These are on a 1-2 mile track right? and what would stock be?

Heres what Vortex sent me.

Changing Gearing

•Adjusting the tooth count in front and rear sprocket changes the way the bike performs.
•A size increase in the rear sprocket and/or a decrease in the front sprocket will favor torque for increased acceleration.
•A size decrease in the rear sprocket and/or an increase in the front sprocket will favor top end speed.
Here's what Vortex sent me. Thanks

Gearing is a key variable in racing. Each rider, bike, and track will demand a different set-up. Though we cannot tell you which will work best for you, the most popular combination for a typical track-day would be a +2 Rear / -1 Front for increaseacceleration without limiting too much top end speed.

You are talking about road racing not 1/4-mile, right?

Stock is 17/40. I haven't run on a track less than 2.5 miles. Miller is 4.5 miles and the front straight is 3/4 of a mile.

I use a gearing calculator and try to match the top end speed of the sprockets to the long staightaway speed I expect to reach without having to change the chain. The bigger the rer sprocket, the more chain it uses and eventually you run out of adjustment.

I'm running a 16/45 and stretched six inches she moves down the pavement.
