Pros and Cons of Installing 120/80-17 Rear Tyres on the TVS Apache RTR 180 2018

Installing 120/80-17 rear tires on a TVS Apache RTR 180 2018, which originally comes with a stock 110/80-17 tire, is a common modification among motorcycle enthusiasts. This upgrade can bring significant changes to the performance and handling of the bike, but it also comes with its fair share of drawbacks. In this article, we will delve into the pros and cons of this modification and help you make an informed decision.

Pros of Installing 120/80-17 Rear Tyres

Increased Grip

One of the most notable benefits of using wider rear tires is the increased grip. A wider tire provides a larger contact patch with the road surface, enhancing traction particularly in corners and during acceleration. This increased grip means that the motorcycle will have better control and stability, especially on twisty roads.

Improved Stability

Wider rear tires can also contribute to improved stability at higher speeds. The larger profile helps the motorcycle feel more planted and secure, making it easier to manage on challenging sections of the road. This can be especially beneficial for riders who frequently encounter high-speed turns and need to rely on strong stability.

Better Ride Comfort

Another advantage is the potential for better ride comfort. Wider tires can offer better shock absorption characteristics, which can significantly reduce the impact of rough road surfaces. This can lead to a more enjoyable and smoother riding experience, especially for long-distance rides or commuting in less-than-perfect road conditions.

Aesthetic Appeal

Fashion and appearance can also play a role in the decision to change tires. Many riders prefer the look of wider tires, as they can give the motorcycle a more aggressive and sporty appearance. This is particularly true for the TVS Apache RTR 180, where the visual impact of a wider tire can make a significant difference in how the bike is perceived.

Enhanced Performance

In specific conditions, such as on racetracks or twisty roads, a wider tire can provide enhanced performance. The increased contact patch and grippy nature of the tire can lead to improved cornering abilities and overall handling, making the bike more responsive when pushed.

Cons of Installing 120/80-17 Rear Tyres

Handling Changes

While the benefits of a wider tire are clear, there are also challenges to consider. One of the primary concerns is the change in handling characteristics. A wider tire can alter how the motorcycle responds to inputs, making it require more effort to lean into turns. Additionally, the bike may feel less responsive compared to the stock tire, which can be a significant adjustment for riders used to the original setup.

Potential for Scrubbing

Another issue is the potential for scrubbing, where the edges of the tire wear unevenly. This can happen if the bike’s geometry is not designed to accommodate the increased tire width. Scrubbing can cause the tire to wear out more quickly, reducing its lifespan and potentially leading to handling issues.

Speedometer Accuracy

Changing the tire size can lead to discrepancies in speedometer and odometer readings. The difference in circumference between the stock and wider tires can cause the speedometer to be inaccurate, which can be problematic for riders who rely on accurate speed and mileage information for navigation or logging their trips.

Clearance Issues

Depending on the design of the bike, installing a wider rear tire can also cause clearance issues. This is particularly common with suspension compression, where the tire can interfere with the swingarm or chain. These clearance issues can lead to operational problems and may require additional modification to resolve.

Fuel Efficiency

Wider tires generally have more rolling resistance, which means that the motorcycle will need to work harder to move. This increased resistance can lead to a slight decrease in fuel efficiency compared to the stock tires, though the difference is usually minimal.

Cost

Finally, the cost of installing wider tires is another factor to consider. Not only are the wider tires themselves more expensive, but you may also need to replace the front tire to achieve a balanced and even appearance. Additionally, installation and any necessary modifications can incur extra expenses.

Conclusion

In conclusion, while installing 120/80-17 rear tires on the TVS Apache RTR 180 2018 can provide significant benefits in terms of grip and stability, it also introduces handling challenges and potential clearance issues. Before making the decision to modify the tires, it is crucial to consider your riding style, the types of roads you frequent, and whether you are willing to adjust your riding techniques accordingly. If you choose to proceed, it is recommended to consult with a motorcycle technician or tire specialist to ensure compatibility and optimal performance.
