gear ratios and speeds
TRANSCRIPT
This spreadsheet was originally started by Sean Hollingsworth of Reno, NVOriginally started in on Saturday, August 11, 2001 12:20:49 AM, and growing a bit since.Very simple. Very easy to modify. Very easy to understand.
I constructed this spreadsheet so that simple numbers can be changed to see how much effect they have on the final speed of whatever motorcycle in any given gear. Orignailly built because I had to know the truth behind the numbers.
On the first Tab "CR500R" I highlighted the numbers in Yellow that can be changed
One of the numbers that may be changed is theDistance covered by one full rotation of the rear tire.
If you are bright enough to Have Excel, then you're bright enough to understand this spreadsheet.
Distrubute freely, but please keep this Worksheet intact :)
