With torque in foot pounds:. Another very important factor that the excellent Gearing Commander site calculates for is repeat contact rate between a given tooth and a specific chain roller, this is based on both sprocket sizes AND the number of links in the chain.
Anyway well worth checking out before changing gearing, dropping just one tooth in front caused big problems on this particular bike Horsepower increases with the engine speed until well after the torque peak, and only peaks when the decreasing torque compensates for the increasing rpm.

|Aussie Street Bikes. For a given torque at the rear wheel, the acceleration of the bike is the same, irrespective of the engine speed. This is where we correct our gearing back to stock, or try to change things up to better handle bike performance in relation to how we want it to perform.
Determine the number of links your chain should be to have a big enough adjustment range Information you will need to get started I am assuming your bike is already profiled in the Gearing Commander website.
Additionally, you will want to view the speed and RPM charts in the middle of the page to determine the changes you will see to your bike. I ignorantly had a shop install a set of Dunlop D, not knowing the size was going to be different.
The difference between the speeds of the two gears is called the speed ratio or gear ratio. Gearing a bike up to produce higher top speed with less acceleration is done using larger effect on the gearing than changing one tooth on the rear sprocket. Gearing your dirt bike is a compromise ratio and as soon as you change your conditions, you might need a new compromise. Here are our best.

Besides these you could also change the gearbox ratio's and Primary Drive Ratio although that takes some "major surgery".
Although gearing ratios aren't as critical to off-road riders as they are street applications, it's always nice to know where you stand. For most of us here, we want the best power down-low power delivery that will allow finesse in the rough stuff, and we can sacrifice some top speed.
