The SEYOUN SY-S004 is a high-performance, stylishly designed motorcycle and scooter tire engineered for high-speed urban commuting, rapid wet-weather water evacuation, and confident cornering stability. Available in popular 10-inch fitments—90/90-10 and 100/90-10—this tire serves as an eye-catching performance upgrade for sport scooters, street commuters, and modern electric two-wheelers.
Featuring a slick central traction strip flanked by organic flame-shaped hydro-grooves, the SY-S004 channels surface water away from the tire footprint to eliminate hydroplaning in heavy rain. Its micro-textured shoulder blocks increase rubber-to-road friction during leaning maneuvers, providing enhanced lateral stability when negotiating city turns. For international B2B tire importers, wholesalers, and aftermarket retailers, the SY-S004 delivers a winning blend of aggressive styling and practical riding safety.
SY-S004 Tread Pattern DesignContinuous Center Crown Strip : An unbroken slick center line optimizes rubber contact during high-speed straight-line riding, reducing vibration, minimizing rolling resistance, and improving wear longevity.
Biomorphic Flame Hydro-Grooves : Aesthetically distinct, curved lateral channels rapidly disperse standing water toward the outer shoulders, maintaining firm tire grip on rain-slicked asphalt.
Micro-Textured Shoulder Anti-Slip Zone: Engineered textured finish on the outer shoulder blocks provides extra biting traction at lean angles, preventing lateral skidding during sharp turns.
High-Grip Thermal Rubber Compound : Formulated to warm up quickly for immediate road friction while resisting tread degradation during prolonged high-speed operation.
1.Excellent Wear Resistance 4.Strong Load Capacity
Special tread compound ensures even wear and longer tire life. Reinforced carcass provides excellent load-bearing performance.
2.Enhanced Wet Traction 5.Long Mileage Performance
Deep grooves and slopes design provide superior grip on wet roads. Optimized foot print distribution promotes even wear and longer mileage.
3.High-Speed Stability 6.Safe & Reliable
Optimiced pattern and structure enoure stable performance at high speeds. Superior stablity and braking performance ensure driving safety.
As a rubber production combined with steel and other materials, tires can be eroded slowly by chemicals, oil, heat, and ozone. The main raw materials of tires include natural rubber and synthetic rubber from petroleum products, so tires exposed to high temperatures heat or fire sources will cause fires that are difficult to extinguish.
Tires should be stored in a cool, dry, clean warehouse to prevent rain, dust, and light. Tires should be placed away from electric generators/motors and sources of heat such as hot pipes. Storage surfaces should be clean and free of grease, gasoline, diesel fuel, or other substances that can deteriorate the rubber. Please rotate tires every month if they are upright in storage. If tires have to be stored outdoors, the place should be:
Improper storage can damage your tires in ways that may not be visible and can lead to a
failure resulting in serious personal injury or death.
Avoid mixing with trucks transporting oil and chemicals. Tire transport vehicles should be equipped with adequate fire equipment. When using a forklift to handle truck tires, install the correct accessories for the forklift, such as tire stackers, tire handlers, etc. Any improper handling ways may cause damage to the tire. For example, the keen-edged forks can bring damage to the bead if you use the forklift without proper accessories.
Proper mounting procedures must be followed or sudden tire destruction, personal injury or death may result. Tire mounting must be done only by personnel trained, supervised and equipped according to local regulations and following the processes requirement of the industries. Always inflate tire/rim assembly in an approved safety cage or equivalent restraining device
