Review:Gearing Commander

"Gearing Commander is a tool to calculate online the effect 
of changing various parts of a motorcycle's drive train."

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 400 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.

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 Ratio Chart

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.
