Dunlop D402 Front Tire MH90-21 54H Narrow Whitewall Harley Touring Motorcycle Tire

OVERVIEW

The Dunlop D402 is a tubeless front motorcycle tire engineered for heavy‑duty touring platforms that require reliable pavement contact and sustained structural durability. Built around an MH90‑21 footprint with a composite bias casing, this component delivers predictable steering response while preserving traditional touring aesthetics for heritage‑inspired machines.

ENGINEERING & PERFORMANCE
