YSS Aerox Rear Shock Absorber Black Red TB220-305T-02-85P

The YSS TB220-305T-02-85P Rear Shock Absorber is a high-quality aftermarket suspension upgrade designed for Yamaha Aerox scooters. Engineered by YSS, a globally trusted suspension manufacturer, this gas-charged twin shock system is developed to improve ride comfort, stability, and handling performance compared to stock OEM suspension. It is ideal for daily commuting, urban riding, and long-distance travel where consistent damping performance and improved ride control are required.

This model uses a double-tube gas (DTG) suspension system, which incorporates nitrogen gas pressure to reduce shock fade and maintain stable damping performance even under continuous load or rough road conditions. The internal hydraulic mechanism works together with a precision-calibrated spring system to absorb road impacts efficiently, delivering a smoother and more controlled riding experience across uneven road surfaces.

The shock absorber is built with a durable steel body and finished in a sporty Black & Red color combination, offering both performance enhancement and visual upgrade for the Yamaha Aerox. The 305mm length specification ensures proper fitment for Aerox 155 models (2017–2023 depending on variant compatibility). Its preload adjustable spring allows riders to fine-tune suspension stiffness based on load conditions such as solo riding, pillion use, or luggage carrying.

The progressive spring design helps maintain comfort on small bumps while providing firmness under heavier compression, improving overall ride stability during acceleration, braking, and cornering. The damping system is tuned to reduce vibration transfer to the chassis, improving rider comfort and reducing fatigue in daily use.

Overall, the YSS TB220-305T-02-85P offers a balanced combination of comfort, durability, and performance, making it a reliable upgrade for riders seeking improved suspension response over stock Aerox rear shocks.
