Maximize Performance: Upgrading Your Ns 200 Rear Tyre to 130/80/18 – The Ultimate Guide

When it comes to maximizing the performance of your Bajaj Pulsar NS 200, one of the most common questions that arise is about tyre upgrades. Specifically, many riders wonder if they can substitute the default 130/80/17 rear tyre with a 130/80/18 sized tyre. The answer is yes, you can, but there are several factors to consider before making this change. This guide will walk you through the process and provide you with the necessary information to make an informed decision.

Understanding Tyre Sizes

Before we delve into the specifics of upgrading your NS 200 rear tyre, it’s important to understand what the numbers in the tyre size mean. The first number (130) represents the width of the tyre in millimeters. The second number (80) is the aspect ratio, which is the height of the tyre sidewall as a percentage of the width. The last number (17 or 18) is the diameter of the wheel in inches.

Benefits of Upgrading to a 130/80/18 Tyre

Upgrading your NS 200 rear tyre to a 130/80/18 can offer several benefits. These include:

  • Improved Stability: A larger tyre can provide better stability, especially at high speeds. This can make your ride smoother and safer.

  • Better Grip: A larger tyre can also offer better grip, especially on wet roads. This can improve your bike’s handling and braking performance.

  • Enhanced Look: A larger tyre can give your bike a more aggressive and sporty look.

Considerations Before Upgrading

While there are benefits to upgrading your NS 200 rear tyre, there are also some considerations to keep in mind:

  • Fitment: Ensure that the larger tyre can fit in your bike’s swingarm and fender. You may need to make modifications to accommodate the larger size.

  • Speedometer Accuracy: A larger tyre can affect the accuracy of your speedometer. You may need to recalibrate it after the upgrade.

  • Fuel Efficiency: A larger tyre can decrease your bike’s fuel efficiency due to increased rolling resistance.


Upgrading your NS 200 rear tyre to a 130/80/18 can improve your bike’s performance and look. However, it’s important to consider the potential fitment issues, speedometer accuracy, and fuel efficiency before making the change. Always consult with a professional or your bike’s manufacturer before making any major modifications to your bike.
