Have you ever wanted to change a sprocket on your motorcycle to change the performance but didn’t know how to calculate the formulas? Well look no further the guys over at Gearing Commander have created an online tool which allows you to calculate the different sprocket sizes according to your particular motorcycle model. What a great tool for trying to figure out what sprocket you may need for different tracks or just want to change the acceleration off the line.
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”….
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 Offline version!
