What is the Difference Between Dunlop D401 and D404?

Introduction

When it comes to motorcycle tires, Dunlop is a well-known and trusted brand. They offer a wide range of tires for various types of motorcycles and riding preferences. Two popular options from Dunlop are the D401 and D404 tires. While both tires are designed for motorcycles, there are key differences between them that riders should be aware of before making a purchase decision.

Construction and Design

The Dunlop D401 is a bias-ply tire, meaning it is constructed with layers of fabric cords running diagonally across the tire. This design provides excellent stability and a smooth ride. On the other hand, the Dunlop D404 is a radial tire, constructed with layers of cords that run perpendicular to the direction of travel. Radial tires are known for their excellent grip and cornering capabilities.

Additionally, the tread patterns of the D401 and D404 differ. The D401 features a more traditional tread pattern with deep grooves, designed to provide optimal traction on both wet and dry surfaces. The D404, on the other hand, has a flatter and wider groove pattern, which helps with water dispersion and offers enhanced stability.

Performance and Handling

When it comes to performance, both the D401 and D404 offer excellent handling characteristics. The D401 excels in providing a smooth and comfortable ride, making it ideal for long-distance touring. Its bias-ply construction helps absorb road imperfections and reduces vibrations, enhancing rider comfort.

On the other hand, the D404’s radial construction offers improved grip and cornering capabilities, making it suitable for sportier riding styles. It provides excellent stability during high-speed maneuvers and offers precise control, inspiring confidence in the rider.

Tire Life and Durability

Another factor to consider when choosing between the D401 and D404 is their durability and tire life. Generally, bias-ply tires like the D401 tend to have a longer lifespan compared to radial tires like the D404. The D401’s construction allows for more even wear, resulting in extended tire life.

However, it’s important to note that the lifespan of a tire also depends on various factors such as riding style, road conditions, and maintenance. Regular inspections and proper tire care can help maximize the lifespan of either tire.

Pricing

Pricing is often a deciding factor for many riders when choosing tires. Generally, the Dunlop D401 is priced lower compared to the D404. This makes the D401 a more budget-friendly option for riders who want a reliable tire at a reasonable price.

Conclusion

In summary, the Dunlop D401 and D404 are both excellent motorcycle tires, but they cater to different riding styles and preferences. The D401, with its bias-ply construction and traditional tread pattern, offers a smooth and comfortable ride, making it ideal for touring. On the other hand, the D404, with its radial construction and enhanced grip, is better suited for sportier riding styles and offers improved cornering capabilities.

When choosing between the two, riders should consider factors such as their riding style, desired performance characteristics, and budget. Ultimately, both tires provide reliable performance and durability, ensuring a safe and enjoyable riding experience.
