With competition in the 400cc scooter market intensifying, the TEYIN TX 450 breaks through the homogenized competition with its twin-cylinder powertrain, achieving a comprehensive upgrade from its powertrain core to its intelligent features.

Powertrain: Twin-Cylinder DOHC, Pure 398cc Excitement

The TX 450 is equipped with a 398cc twin-cylinder DOHC eight-valve engine, featuring a combined liquid- and air-cooling system. It delivers a maximum power output of 30kW at 8,000rpm and peak torque of 41N·m at 6,500rpm, offering impressive performance within its class. The engine features high-tumble intake ports and a high-efficiency combustion chamber, combined with an all-aluminum cylinder block with a nickel-plated bore. This design not only reduces the overall motorcycle weight but also further improves heat dissipation. A built-in balancer shaft effectively suppresses vibration generated by the twin-cylinder engine. The transmission system adopts a CVT with dual cooling ducts and a double-sided toothed belt, ensuring transmission efficiency while delivering quieter operation.

Technology and Features: Safety and Intelligence Combined

In terms of safety, the TX 450 is equipped with cornering ABS, which can effectively reduce the risk of wheel lock-up during braking while leaned over. It also features a Traction Control System (TCS) and cornering Electronic Stability Control (ESC), working together to continuously optimize vehicle stability in complex conditions such as wet roads and emergency avoidance maneuvers. In terms of intelligent features, the TX 450 integrates a TBOX, Body Control Module (BCM) and Passive Keyless Entry (PKE) system. It also supports smartphone connectivity and remote vehicle control, significantly enhancing convenience in both motorcycle operation and everyday use.

Chassis and Handling: Precise and Composed, Effortless Control

The TX 450 measures 2,167 × 790 × 1,400mm, with a wheelbase of 1,579mm and a seat height of 795mm, accommodating the riding needs of riders of different heights. The scooter is equipped with 120/70-15 front and 140/70-14 rear tires, together with 180mm of ground clearance. This combination balances agility in urban riding with a certain level of capability on more challenging road surfaces. The front suspension adopts a bottom-mounted design, effectively lowering the overall center of gravity, while the 16-liter fuel tank provides ample range for long-distance riding.

Attention to Detail: Quality Enhances the Riding Experience

The TX 450 is meticulously engineered with refined mechanical details, including an external fine filter, a high-performance starter motor and a reverse-mounted clutch driven pulley, creating an overall riding and handling feel that surpasses that of its class. Meanwhile the distinctive exhaust note and rhythmic character of the twin-cylinder engine also embody the core riding enjoyment pursued by motorcycle enthusiasts.

Conclusion

With its twin-cylinder powertrain at the core, the TEYIN TX 450 combines advanced safety technologies with intelligent connectivity features, taking a differentiated approach in the 400cc scooter segment. For scooter enthusiasts who value riding and handling quality, safety features and intelligent riding experiences, the TX 450 is a model worth paying close attention to.
