Dunlop Tires D401 Rear Motorcycle Tire 150/80B-16 (77H) Black Wall — Wet/Dry Traction & Long Wear

The Dunlop D401 Rear 150/80B-16 (77H) Black Wall is a Harley-Davidson-approved cruiser tire engineered for reliable wet and dry traction and long, even wear on big-twin motorcycles.

Built as an original-equipment option for Harley-Davidson cruisers, the Dunlop D401 blends a tread geometry optimized by computer modeling with a tuned rubber compound to deliver predictable handling and extended service life. This specific 150/80B-16 (77H) rear size with a black wall finish fits the Harley-Davidson CVO Dyna Wide Glide FXDWGSE 2002, offering a direct replacement that preserves the bike’s original ride and stability characteristics.

How does the D401 improve grip in wet and dry conditions?

The D401 uses a compound formulated for broad temperature and surface performance, combined with a directional tread pattern that channels water and maintains contact patch consistency. That pairing helps preserve traction whether the pavement is dry or damp, without sacrificing longevity.

• Advanced rubber compound tuned for wet and dry adhesion
• Directional grooves to evacuate water and resist hydroplaning
• Contact patch design for consistent traction under load

Why does the D401 offer even wear and longer life?

Every D401 uses bias or bias-belted construction and a computer-optimized tread profile to minimize cupping and irregular wear patterns. Those engineering features spread forces evenly across the surface and reduce the tendency for uneven tread degradation, helping you get more miles from each tire.

• Bias or bias-belted casing for stable carcass support
• Computer-shaped tread profile to prevent cupping
• Durable compound designed for extended tread life

Will this tire fit my motorcycle and maintain factory handling?

This 150/80B-16 (77H) rear D401 is an approved fitment for certain Harley-Davidson cruisers and matches the original equipment specifications for the CVO Dyna Wide Glide FXDWGSE 2002. Choosing the D401 keeps the bike’s intended geometry and handling balance intact, provided you select the correct front and rear sizes recommended by your owner’s manual.

• Exact match for specified OEM rear size and load/speed rating (77H)
• Black wall finish maintains original cruiser aesthetics
• Designed to preserve factory ride and steering feel

How should I care for and install the D401 to get the best performance?

Proper mounting, correct tire pressures and routine inspections are key to maximizing traction and service life. Use a qualified tire technician for installation, follow Harley-Davidson or Dunlop pressure recommendations, and monitor tread depth and overall condition regularly.

• Have a professional mount and balance the tire
• Adhere to recommended inflation pressures for load conditions
• Check for wear, cuts, and proper tread depth periodically
