The original fitment for the 2021 Harley Davidson 1250 S, the Dunlop GT503 is a modern and high-performance radial tire (Jointless Band (JLB) Construction technology). It combines the power of a wide tire with impeccable handling, more responsive and more consistent while remaining flexible. The aggressive tread pattern has been designed to allow perfect grip on both dry and wet surfaces and controlled wear (new innovative rubber compound).
