The Shinko SR999 Long Haul Front Motorcycle Tire is designed for cruiser riders who demand dependable mileage, confident handling, and consistent road performance on extended journeys. This front tire uses an 80/90-21 size, 54H speed and load rating, bias construction, and tubeless (TL) design to deliver a stable, responsive ride across highways, back roads, and winding routes. Manufacturer part number 87-4914 and vendor part number 87-4914 identify this Shinko replacement tire.
Built for long-distance touring and everyday cruiser use, the SR999 combines a silica-rich compound with an enhanced rubber blend to promote strong wet-weather traction while helping reduce tread wear. The elevated tread depth supports extended service life, making this tire well suited to riders who regularly cover significant mileage. Functional siping and deep tread grooves help evacuate water and maintain grip in both wet and dry conditions, while the reinforced carcass provides a planted feel and stable tracking through varied road conditions.
Aramid belting adds stability and supports substantial load capacity for touring applications. The Shinko SR999 Long Haul is intended as a front replacement tire for compatible cruiser and touring motorcycles that specify an 80/90-21 54H bias-ply tubeless fitment. Always verify the motorcycle manufacturer's recommended tire size, load rating, speed rating, wheel type, and front-wheel application before installation. Professional mounting and balancing are recommended to help ensure proper performance and tire life.
