Author: Sarah @ MetalGear Date Posted:27 July 2021
If you find your OEM gear ratio is not ideal for your style of riding, you can change your set up using the guide below.
By increasing the number of teeth on the front sprocket and decreasing the number of teeth on the rear sprocket results in higher top speed and lower acceleration. Vice versa: decreasing the number of teeth on the front sprocket and/or increasing the number of teeth on the rear sprocket will result in lower top speed and higher acceleration.
There are however some cons to changing from your OEM gear ratio;
• To achieve your desired result it will involve patience. It is a case of trial and error.
• Keep in mind that some vehicles cannot accommodate larger front sprockets so it is vital you check before purchasing your new sprockets.
• You may also need to factor in the cost of a new chain if required.
• Ensure that your new gear ratio has not affected your speedometer.
CALCULATING YOUR CURRENT GEAR RATIO
It's easy: REAR SPROCKET divided by FRONT SPROCKET = GEAR RATIO
From here you can determine if you need a higher gear ratio for more acceleration or lower gear ratio for more top end speed.
