Dunlop OE on Harley-Davidson Sportster S

The Harley-Davidson Sportster S is one of the most anticipated motorcycle launches of 2021. Continuing a Sportster saga that began in 1957, the all-new S model is one of the most powerful bikes in the Harley-Davidson range. The manufacturer tasked Dunlop with developing a tyre designed specifically for its needs, and the result is the Dunlop GT503. The tyre features a new construction and compound, as well as aesthetics to complement the Sportster S.

Dunlop says the new GT503 provides its riders with many advanced features. The radial construction features a Steel Jointless Belt (JLB) 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 Sportster S riders with high levels of dry grip, whereas the long tread grooves enhance riding confidence on wet surfaces. With the newly developed compound, GT503 provides not only excellent grip but also offers high mileage potential.

The tyre features the Harley-Davidson logo on the sidewall emphasising the bespoke design and the strong partnership between the two brands. “We are proud that Harley-Davidson has chosen Dunlop for the Sportster S,” states Luca Davide Andreoni, Dunlop marketing manager Europe. “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 a custom bike look but has been tuned by Dunlop’s experts to deliver the light handling expected of sports bikes.
