final reduction = (rear sprocket teeth/front sprocket teeth)

reduce no of teeth at front or increase teeth at rear = acceleration[lowend]

increase no of teeth at front or reduce teeth at rear = speed [topend]

top gear is less bcoz it is making much greater revolutions .. hence higher speed at wheels wrt per rev of the transmission’s output [is it cam??].

very high ratio of low gears means engine is transmitting very high torque \ power when it is needed the most!!

I think you can take the data from my image posts. It's a Rolon Manual, giving all front & rear sprocket details :-->

http://www.xbhp.com/talkies/desi-bik...sprockets.html

See post #14 for the data you need...

But, I'm confused. Maybe merging the thread is better than reposting the data, What do you say?
