Motorcycle Sprocket SizeRatio Calculator Home Explain Calculate Lookup Request This easy online sprocket calculator will help you determine the effect that different sprockets will have on your motorbike and help you calculate the best sprocket sizes for your riding style.

Your gearing ratio is simply put the ratio of teeth between the front and rear sprockets. This ratio determines how engine RPM is translated into wheel speed by the bike. Changing sprocket sizes front or rear will change this ratio and therefore change the way your bike puts power to the ground.

This section simply attempts to describe the important role of gear ratios. The overall gearing of a motorcycle consists of 3 major parts. The primary drive the ratio between the engine crankshaft and the clutch or gearbox.

The gear box it self depending on the amount of gears this part has an equal amount of ratio to choose from. Calculate Chain and Sprocket Sizes Lengths Ratios RPM and Chain Speeds. Chain Sprocket Calculator Chain Length Sprocket Centers RPM Gear Ratio Chain Speeds.

When changing sprockets you can adjust Chain Links to maintain nearest to current Sprocket Centers eg. To keep motorcycle rear wheel within adjustment range. Your primary drive transmission and rear drive sprockets all combine to determine your cruising rpm as well as your final top speed.

This calculator will show you your speed in each gear from everything from a stock bike to an all out drag bike with a separate jackshaft as well as the one we love the most the Bonneville racer. When the gear ratio goes over 3 the bikes acceleration increases but the top speed decreases. The inverse is true.

When the gear ratio is below 3 the bike loses on the acceleration but gains top speed. The reason for this is very simple. Due to the increase in the front sprocket or reduction in the rear sprocket teeth the ratio decreases.

Colors group similar values. 3 is green 2-3 blue and below 2 red. To find this number divide the number of teeth on the rear by the number on the front.

Keep this ratio in mind when choosing sprockets. Should the numerical value increase youre gearing the motorcycle down That means a decrease in the ratio results in gearing up. How to calculate bicycle gear ratio.

Simple just divide your rear cog size from your front chainring size. If you know their numbers just input them below and well calculate it automatically for you. Also take a look at our complete bicycle gear ratio chart below to see how your size compares to other gearing options.

Below are the two graphs the motorcycle gearing calculator produced for the CB500K2 at 8000 rpm and 9530 rpm. 1973 Honda CB500K2 Calculated Speed in Gears at 8000 rpm by Blocklayer online calculator. If youre using a Schlumpf Drive plus an internal-gear rear hub you should enter the actual number of teeth of the front chainring for the first chainring and this number of teeth times the Schlumpf ratio for the second chainring.

The ratios are 040 for the Mountain Drive 165 for the Speed Drive and 250 for the High Speed Drive. Colors group similar values. 80 is green 50ish-80 blue and below 50 red.

The gear ratio is now 3331 meaning the front sprocket has to rotate 333 times before the rear sprocket rotates once. As a decimal number this ratio now becomes 03 15 50 03. So as you can see before the change the ratio as a decimal number was 033 after the change the gearing has been lowered to 03.

The Changes in Real Terms. Most bikes with derailleur gears have either 5 6 7 8 9 10 or even 11 or 12 sprockets on the hub along with 1 2 or 3 chainrings. The calculator has now been updated to accommodate up to 12 speed rear.

Gear ratios on a bicycle are expressed in inches or cm as an effective wheel diameter.
