I'm getting comfortable on my 250 and would like to know what is the proper gear ratio to hit over a100mph?

Check the search, type in "Maxton" and start there.

with the 250, and it's small amount of power, there are lots of variables to consider.... Ghost is right, search for Racer X and his Maxton land speed record pursuits...

With a stock bike I would run a 15/43 or 15/44. Depends on rider weight. I run a 16/42 on the track .that would suck on the street
