What is it
"Gearing
Commander is a tool to calculate online or offline the effect of
changing various parts of a
motorcycle's drive train."
Gearing
Commander answers all your motorcycle gearing questions and more !
• You
want to get a little faster of the line ?
• You want some more top speed ?
• You want some more gas mileage (MPG) ?
• You want to know how another rear tire size affects your gearing and
speed ?
• You want to know what chain length to use after changing sprockets ?
• You want to know what sprocket combination causes the least chain and
sprocket wear ?
• You want to know how to set your SpeedoHealer correctly ?
You have
come to the right address so stop searching and start using it.
Lot's of
motorcycle owners want their bike to behave differently from stock or current
setup at certain speeds or RPM. In that case there are several ways to
achieve that and one of them is changing the gearing. The Gearing Commander can
be used to predict the effect the change will have and thus save you spending
money on the wrong parts !
The most common
changes people make are different
Rear Sprocket, different
Front Sprocket, different
Tire size and different
Chain as a result of sprocket change. Besides these
you could also change the gearbox ratio's and Primary Drive Ratio although that takes
some "major surgery". The Gearing Commander's database stores all
involved gearing specifications for over 600 bikes and uses them to calculate
speeds, RPM's, chain length etc. By selecting your bike and changing the 1 or
more variables you can predict the theoretical outcome without having to spent
money on experiments !
Because
results are calculated online, you yourself can
change all gearing fields
loaded from the database and see the calculated results
!
Using the Gearing
Commander you can:
|
1. |
See
theoretical top speed of your bike in all gears |
|
2. |
See effect
of sprocket changes on speed at specific RPM |
|
3. |
See effect
of sprocket changes on RPM at specific speed's |
|
4. |
Compare
speeds in stock, current and custom setup related to gear and RPM |
|
5. |
Compare top
speeds in custom setup for 49 sprocket combinations for use on the racetrack |
|
6. |
See effect
of other rear tire dimensions (for instance wider) on (top) speed and
gearing |
|
7. |
Calculate Tire
circumference for setting of cycle computer |
|
8. |
See effect
of sprocket changes on sprocket center distance (i.e. rear wheel travel
needed to tighten the chain) |
|
9. |
Determine
the number of links your chain should be to have a big enough adjustment
range |
|
10. |
Decide
on whether to have a smaller front sprocket or to have a bigger
rear sprocket |
|
11. |
Determine the
optimum tooth-links combination to minimize chain and sprocket wear |
|
11. |
Calculate
changes on the race track without an internet connection using
the Stand
Alone version! |
|
12. |
Turn most
result tables into
charts
and graphs
for a more visual effect of the changes |
|
13. |
In Shift-Speed
graph see results of changing sprockets on Shift-Speeds in all
gears & setups (Speed range/gear) |
|
14. |
Create custom
Final Drive Ration Chart |
|
15. |
Calculate
correct SpeedoHealer settings |
All
calculations are based on the specific gearing data of a bike either
entered by you or loaded from the database.
All information
provided is based on theoretical calculations in optimal conditions and therefore
it will differ from reality. For instance all chain calculation are without
taking into account the chain wear and current tension. Also all calculations
depend on the M.P.RPM entered but there is no guarantee that your bike will
actually reach M.P.RPM. This depends on the power your bike delivers and mainly
the wind resistance.
So please use all
results as guidelines rather then facts !
