Get the authentic, smooth-rolling cruising performance your heavy cruiser demands with the premium Dunlop D402 Front Motorcycle Tire [MPN: 45006380]. Masterfully co-engineered as the official original equipment street tire line for heavyweight American touring platforms, this tire establishes an absolute balance between high mileage, stable wet-weather tracking, and consistent steering response. Built with an advanced computer-optimized tread profile, it ensures exceptional front-end stability and long, even wear characteristics throughout the entire lifespan of the casing.
Part number 45006380 is manufactured using a specialized high-capacity MT90B16 front touring configuration (equivalent to a modern 130/90-16 specification). Meticulously cross-referenced against factory assembly logs, this wide-whitewall front tire is a verified direct replacement fit for the following heavyweight applications running a 16-inch front wheel rim layout:
CRITICAL TUBE TYPE RE-INTEGRATION, RADIAL STRUCTURAL EXCLUSIONS, AND BREAK-IN WARNINGS:
**Tubeless vs Tube Type Rim Logic:** This tire features a standard Tubeless (TL) bead design construction. **It can be safely run completely tubeless on modern factory mag/alloy wheels**. However, if your cruiser utilizes traditional chrome spoke or laced wire wheels, **you must install a heavy-duty motorcycle inner tube and fresh rim strip during mounting**. Running a tubeless tire on a spoked wheel without an inner tube will cause immediate, dangerous pressure failure.
**Bias-Ply Construction Frame Warning:** The D402 is a **Bias-Belted (B)** construction tire. It should **never** be mixed on a motorcycle with a radial tire, and it cannot be used on late-model 2009-up touring frames that were factory-engineered strictly for advanced low-profile multi-compound radial tire tracking geometry. Mixing tire constructions can cause severe chassis instability.
**Load and Speed Rating Compliance:** This casing carries a heavy-duty 72H metric index rating, meaning it is safety-certified to support a maximum static load capacity of 783 lbs at a peak continuous speed of 130 MPH. Do not exceed these structural parameters under full multi-day luggage and passenger weights.
**Critical 100-Mile Tire Break-In Protocol:** Brand new motorcycle tires feature a slick mold-release sheen on the outer tread surface straight from the manufacturing assembly plant. **Riders must exercise extreme caution during the first 100 miles of operation**. Avoid sudden heavy acceleration, hard braking, or aggressive lean angles until the tread compound has been scuffed cleanly against raw pavement to establish full friction traits.
