Meticulously cross-referenced against factory vehicle assembly logs, this tubeless bias-belted tire serves as the exact original equipment (OE) specification or premium direct upgrade for the front wheel on the following Harley-Davidson motorcycles:
CRITICAL SIDEWALL FINISH & TUBELESS MOUNTING WARNINGS:
**Finish Verification:** Please be aware that manufacturer part number 45006823 corresponds explicitly to the classic **Blackwall (BW) Sidewall** configuration . If your customer's motorcycle restoration or personal styling requires the Medium Whitewall (MWW) or Wide Whitewall (WWW) layout, you must select the separate designated companion SKU (such as MPN 45006206) to ensure the correct aesthetic match .
**Rim and Inner Tube Warning:** This is a Tubeless (TL) rated tire designed to seat cleanly without an inner tube on factory cast or sealed tubeless aluminum wheels . However, because many traditional 21-inch Harley-Davidson configurations utilize standard laced wire-spoke wheels, **you must install a brand-new 21-inch inner tube and rim strip if mounting this tire onto non-sealed spoke rims**. Operating a tubeless tire on standard spoke wheels without an inner tube will cause rapid, catastrophic air pressure loss through the spoke nipples. Always consult a certified tire professional prior to finalized inflation.
