Problems of Using a 100/70-17 Tyre Instead of Stock Tyres for TVS Apache 200

Introduction

The question often arises when owners of motorcycles like the TVS Apache 200 consider replacing the stock tyres with a different type, such as a 100/70-17 tyre on the front. While the differences may seem insignificant, there are several reasons why sticking to the recommended tyres is the best choice.

Speedometer Error and Performance

One of the most noticeable issues when swapping to an unconventional tyre size is the potential speedometer error. The speedometer relies on the dynamics of the wheel to calculate speed accurately. A tyre with a different circumference, like a 100/70-17 instead of the stock 90/90-17, could lead to inaccurate readings. This can be particularly problematic if you are relying on speedometer signals for certain maneuvers or if you are on a track or race.

Grip and Handling

The second major concern is tyre grip and handling. The original equipment manufacturer (OEM) tyres are designed to provide optimal performance for the intended specifications of the motorcycle. The 100/70-17 tyre may offer some improved grip due to its increased width. However, this improvement is often minor and comes at the cost of cornering clearance and handling agility. Motorcycles are finely tuned machines, and the slight increase in grip might be outweighed by the loss of agile handling characteristics.

Effect on Cornering Clearance and Design

The cornering clearance and agility of the motorcycle can be impacted by the replacement of the stock tyres. Different tyre sizes can alter the geometry and handling dynamics, leading to a less predictable and potentially less stable ride. While a 30mm difference in tyre width might not seem significant, it can make a noticeable impact on how the motorcycle behaves.

Poor Quality Tyres and Negatives

Using a tyre of poor quality can compound the issues mentioned above. Malfunctioning tyres can not only compromise your safety but also lead to decreased performance and more frequent maintenance. These inferior tyres are more prone to blowouts, uneven wear, and other types of failure, all of which can put you at significant risk while riding.

Conclusion

In conclusion, while the differences between a 100/70-17 tyre and a stock 90/90-17 tyre on a TVS Apache 200 may seem minor, they can have a noticeable impact on the performance, safety, and handling of the motorcycle. The team who designed your motorcycle put a lot of thought into the tyre specifications for a reason. It is always advisable to stick to the recommended tyres to ensure optimal performance and safety.

Additional Advice

For those who are particular about tyre performance, consider using tyres of the same size and higher quality. This will not only enhance your riding experience but also ensure that your motorcycle remains within the manufacturer's specifications, minimizing any potential issues.
