Dunlop GT503 ex works on new Harley-Davidson Sportster S
• Newly developed Harley-Davidson tire with a particularly sporty design
• Development focus: dry and wet performance
• Sizes: 160/70R17 (front) and 180/70R16 (rear)
Without a doubt, the brand new Harley-Davidson Sportster S is one of the most anticipated motorcycle innovations of 2021. It is even one of the most powerful bikes within the Harley-Davidson product range. Dunlop was exclusively commissioned by Harley-Davidson to develop a new tire specifically tailored to the requirements of the Sportster S. The result of the collaboration is the newly designed Dunlop GT503, which offers Sportster S pilots excellent driving characteristics. The profile design is particularly sporty and matches the dynamic appearance of the Sportster S.
Not only does the GT503 tire profile convey progressiveness, the new Harley tire also offers innovative technologies under the tread. The radial construction features the proven JointLessBelt technology (endlessly wound zero-degree belt), which is also used in Dunlop's hypersport and sport touring tires. The advantages are neutral handling across the entire lean angle, more stability at higher speeds and excellent feedback.
In addition, the tire contour was shaped in such a way that the contact area with the asphalt is increased and remains consistently large in order to offer a high level of grip - regardless of the lean angle. In combination with the new rubber compound, Sportster S drivers can rely on safe and sporty driving characteristics on dry and wet roads.
Like many other exclusive Harley-Davidson tires from Dunlop, the GT503 also bears the Harley-Davidson logo on the sidewall. Commenting on the strong partnership between the two brands, Luca Davide Andreoni, Dunlop Marketing Manager Europe, said: “We are proud that Harley-Davidson has chosen Dunlop as the original equipment tire brand for the Sportster S. It was exactly 40 years ago when Harley-Davidson and Dunlop started working together on the original Sportster models. Since then, Dunlop has supplied over 10 million original equipment tires to Harley-Davidson. With the GT503, Dunlop continues this strong collaboration in developing innovative tires to meet the demanding requirements of the manufacturer and its customers.”
The GT503 is mounted on the new Sportster S in sizes 160/70R17 (front) and 180/70R16 (rear). The wide front tire size provides a cool custom bike look, but also offers the light handling expected of sports bikes.
