Product Description
YIPOWER 107cc Underbone
107cc Underbone Motorcycle – 4-Speed Auto-Clutch, 80 km/h, 95 kg – Lightweight Commuter for City & Suburb

Meet the YIPOWER 107cc Underbone—a lightweight, fuel-efficient motorcycle built for daily commuting and urban versatility. Designed with a horizontal CB single-cylinder 4-stroke engine, this model delivers 5.2 kW of power at 7500 rpm and 7.0 Nm of torque at 6000 rpm, providing smooth acceleration and reliable performance through city streets and suburban roads.

The automatic wet multi-plate clutch and 4-speed cycle shift pattern (1-2-3-4 cycle) make riding effortless—no manual clutch operation needed. Just twist and go. Whether you're navigating morning traffic or cruising at up to 80 km/h, this bike offers a stress-free experience for riders of all skill levels.

Weighing only 95 kg with a 150 kg load capacity, the YIPOWER is exceptionally easy to handle. The 850 mm seat height and 1240 mm wheelbase provide a stable yet agile riding position, while 120 mm of ground clearance handles speed bumps and uneven surfaces with confidence.

Safety is backed by front and rear drum brakes, paired with telescopic front forks and a rear swing arm suspension system for a balanced, comfortable ride. The 4 L fuel tank and efficient 9.2:1 compression ratio keep you on the road longer between fill-ups.

Built with practical features, this model comes equipped with 2.5-17 front and 2.75-17 rear tires mounted on durable steel rims (1.4*17 front, 1.6*17 rear). The electric and kick start system ensures reliable ignition in all conditions, powered by a 12V 5Ah lead-acid battery and an 8-class single-phase charging system.

Whether you're commuting to work, running errands, or exploring the neighborhood, the YIPOWER 107cc Underbone delivers the perfect balance of simplicity, efficiency, and everyday utility.
