Trike Gear Ratio Calculator

Trike Gear Ratio Calculator

Are you a passionate motorcycle enthusiast eager to elevate your bike’s performance to new heights? If you’re serious about optimizing your motorcycle’s balance of power and speed, understanding gear ratios is essential.

The Trike Gear Ratio Calculator is a valuable tool designed to assist you in making informed decisions about your motorcycle’s gearing.

In this comprehensive guide, we will guide you step by step through using this calculator effectively, ensuring you can fine-tune your bike for an exhilarating riding experience.

Step 1: Input Your Engine RPM

The initial parameter you need to enter into the Trike Gear Ratio Calculator is your motorcycle’s Engine RPM (Revolutions Per Minute).

This value represents the number of times your engine’s crankshaft rotates in a minute. You can typically find this information in your motorcycle’s user manual or consult a professional mechanic.

Enter this value accurately in the “Engine RPM” field.

Step 2: Determine Your Rear Wheel Diameter

Next, you will need to determine your Rear Wheel Diameter in inches. This measurement refers to the size of your motorcycle’s rear wheel, specifically its diameter.

Once again, you can usually find this information in your motorcycle’s specifications. Be sure to enter this value precisely in the “Rear Wheel Diameter (in inches)” field.

Step 3: Identify the Primary Drive Ratio

The Primary Drive Ratio is a critical aspect of your motorcycle’s transmission system, defining the relationship between the engine’s crankshaft and the primary drive pulley.

Consult your motorcycle’s technical documentation or seek guidance from a professional mechanic to find this ratio. Enter it accurately in the “Primary Drive Ratio” field.

Step 4: Determine the Secondary Drive Ratio

The Secondary Drive Ratio is associated with the final drive system, including the sprockets and the chain or belt that connects the engine to the rear wheel.

Much like the Primary Drive Ratio, you can acquire this information from your motorcycle’s documentation or a knowledgeable mechanic. Input it into the “Secondary Drive Ratio” field.

Step 5: Calculate Your Gear Ratio

Once you have populated all the required fields, click the “Calculate Gear Ratio” button. The Trike Gear Ratio Calculator will process your inputs and provide you with a precise result.

This result is your motorcycle’s calculated gear ratio.

Understanding the Result

The result displayed by the calculator represents your motorcycle’s gear ratio. This figure is crucial for motorcyclists as it directly influences factors such as acceleration, top speed, and fuel efficiency.

The gear ratio essentially measures how effectively your motorcycle can convert engine power into wheel rotation.

A higher gear ratio offers greater top speed but may reduce acceleration, while a lower gear ratio enhances acceleration but can limit top speed.

Depending on your riding style and the type of terrain you encounter, you can adjust your motorcycle’s gear ratios to align with your preferences.


In the realm of motorcycle tuning, comprehending and optimizing gear ratios is paramount.

The Trike Gear Ratio Calculator empowers you to make data-driven decisions regarding your motorcycle’s gearing.

By entering your Engine RPM, Rear Wheel Diameter, Primary Drive Ratio, and Secondary Drive Ratio, you can effortlessly calculate your gear ratio and tailor your bike’s performance to your liking.

With this potent tool at your disposal, you are well on your way to realizing the ride of your dreams. Enjoy the open road!
