DUNLOP Harley‑Davidson D402 Front Tyre MT90B-16 — Tubeless Touring, Long-Wear Wet Grip

Designed and validated in partnership with Harley‑Davidson®, the D402 front tire balances stability, wet-weather confidence, and long wear for riders who cover long miles. Its bias construction, three-ply polyester casing and dual fiberglass belts deliver a stable contact patch while a computer-optimized tread profile reduces cupping and improves steering feel on varied surfaces.

How does the D402 improve stability on long-distance rides?

The D402 uses a robust casing and belt package to resist flex under load, keeping the front end predictable at highway speeds and when carrying luggage or a passenger. That structural rigidity helps maintain consistent steering geometry through extended trips and varying pavement conditions.

• Three-ply polyester casing provides torsional strength for touring loads
• Two fiberglass belts reduce tread movement for steadier handling
• Approved for Harley‑Davidson touring models for matched performance

Will this tire handle wet roads and road irregularities?

The tread pattern includes an offset center groove and computer-optimized profile to evacuate water and improve contact over rain grooves and metal surfaces. These design choices enhance rider confidence without sacrificing evenness of wear.

• Offset center groove improves water evacuation and traction
• Optimized profile reduces sensitivity to rain grooves and steel-grated bridges
• Tread geometry minimizes cupping for steadier wet and dry grip
