Dunlop Tires D402 Front Motorcycle Tire MH90-21 (54H) Black Wall — Touring Front Tire with Long-Wear and Wet Traction

The Dunlop D402 MH90-21 (54H) front motorcycle tire is a Harley‑Davidson–approved touring tire engineered for long wear, stability, and reliable wet-road performance.

Designed as the factory-approved front replacement for many Harley‑Davidson touring and Sportster models, the D402 brings a mix of construction features that prioritize load capacity, even tread wear and predictable feel on a variety of road surfaces. Its three-ply polyester casing with two fiberglass belts and a computer-optimized tread profile aim to deliver consistent contact and confidence across dry, wet and irregular surfaces, while available black, single-white or wide-white sidewall options let you match the bike's aesthetic.

How does the D402 improve stability and load carrying on a Harley?

The D402 uses a three-ply polyester casing combined with two fiberglass belts to increase structural strength and resist deformation under load. This combination helps maintain a consistent footprint at highway speeds and during touring loads, contributing to steadier handling and reduced flex.

• Three-ply polyester casing for increased durability and load capacity
• Two fiberglass belts to stabilize the tread area at speed
• H speed rating (up to 130 MPH) supports highway touring use

What makes the tread pattern suitable for wet and rough surfaces?

The D402’s computer-optimized tread profile features an offset center groove and patterned siping intended to shed water and improve contact across irregular surfaces. The design reduces cupping, promoting more uniform wear while helping the tire track predictably over rain grooves, steel bridges and other textured pavement.

• Offset center groove to help channel water and maintain grip
• Tread geometry tuned to reduce cupping and extend even wear
• Profile engineered for consistent contact patch on rough pavement

How does installation and aesthetic customization work?

The D402 is offered in multiple sidewall finishes—black wall, single-white or wide-white—so you can match the original equipment look or update your bike’s style. Installation follows standard motorcycle tire mounting and balancing procedures; fitting to the specified rim size MH90-21 ensures intended performance and safety characteristics.

• Available in black wall, single-white or wide-white sidewall options
• Fits 21-inch front rims when using MH90-21 size specification
• Requires professional mounting and proper balancing for best results

Which models and years is this tire compatible with?

This D402 MH90-21 (54H) front tire is compatible with many Harley‑Davidson Sportster and touring models; it has been factory-approved for select Harley applications. Always verify the exact year and model fitment—such as XL1200C Sportster 1200 Custom—and confirm load/speed ratings before purchase.

• Compatible with Harley‑Davidson Sportster 1200 Custom (XL1200C) model ranges
• Check year-by-year fitment for specific Harley models (1996–2010 noted examples)
• Confirm 54H load/speed rating matches your motorcycle’s requirements

Who is this for: Riders who want a Harley‑approved front touring tire with an emphasis on structural stability, predictable wet-road behavior and classic styling options. If you tour regularly, carry heavier loads, or prefer original-equipment fitment and appearance for Harley models like the Sportster 1200 series, the D402 MH90-21 (54H) is designed to meet those needs without sacrificing the option to customize your bike’s sidewall look.
