Gearing Commander: Theoretical Top Speed

In table "Speed in Mph related to Gear and RPM in ¡ Stock ¡Current ¤Custom setup"  and  table "Top speed related to gear and front/rear sprocket combination in at Max.RPM:" you can read your top speed in highest gear at maximum RPM.

Bear in mind that it is very difficult to actually reach the theoretical maximum RPM in the highest gear !
This calculation merely shows the (correct !) speed when actually running the maximum RPM in highest gear.

It DOES NOT guarantee that your bike can actually reach the stated maximum RPM and resulting top speed in top gear !


The maximum RPM reached in Top gear mainly depends on available horsepower and wind resistance. The wind resistance depends on bike speed (when your bike speed doubles, the wind resistance increases by a factor 4 !), rider weight, rider height, wind speed, wind direction and so on and so on...


The Max. RPM in the Gearing Commander database is the RPM when reaching the top of the power curve (Max power @ x RPM) stated by either manufacturer (when available), bike reviews, published Dyno-runs or other sources when available. It is not the Red-Line or Rev-limiter RPM ! But since you can change the value of this field as well, you can enter the RPM you think your bike is making ....

BTW: It also does not mean the calculator is off when it shows a top-speed higher then you've ever seen on the bike or the dyno...
