Dunlop GT503 development

It really is all change at Harley-Davidson, what with the Livewire and the Pan America recently launched, and now the Sportster S, which is one of the most powerful models in the Harley-Davidson range. Dunlop have been releasing and updating so many of their tyres recently too, that it’s hard to keep track, but they were also tasked with developing an advanced new tyre designed specifically for the Sportster S.

The Dunlop GT503 features a new tyre construction and compound to provide great performance while the aggressive look of the tread pattern matches the dynamic appearance of the Sportster S.

The new GT503 provides riders with a radial construction featuring Steel Jointless Belt technology, which delivers more responsive and consistent handling while also providing a compliant ride. The tread pattern on GT503 has been developed to maximise the contact patch and provide high levels of dry grip, whereas the long tread grooves enhance riding confidence on wet surfaces. With the newly developed compound the GT503 provides not only excellent grip but also offers high mileage potential.

Luca Davide Andreoni, Dunlop Marketing Manager Europe, said: “We are proud that Harley-Davidson has chosen Dunlop for the Sportster S. It is exactly 40 years since Dunlop was asked to develop specific tyres for the original Sportster. Since then, Dunlop has supplied over 10 million original equipment tyres to Harley-Davidson, highlighting the close partnership. With the Dunlop GT503 Dunlop continues that relationship in developing innovative tyres to meet the demanding requirements of the manufacturer and their customers.”

GT503 will be available in front: 160/70R17 and rear: 180/70R16 sizes. The wide front tyre size provides the custom bike look but has been tuned by Dunlop’s experts to deliver the light handling expected of sports bikes.
