Carve through city streets with confidence aboard the ZFYC 225cc Street Motorcycle—a lightweight, agile machine designed for urban riders who value style, efficiency, and everyday practicality. Whether you're commuting to work or cruising weekend boulevards, this street bike delivers responsive performance with head-turning good looks.
Power comes from a proven horizontal single-cylinder, air-cooled 225cc engine delivering 12 kW at 7500 ± 500 rpm and 17.5 N·m of torque across the same range. The 9.0:1 compression ratio provides peppy throttle response while maintaining the reliability ZFYC is known for. DC-CDI ignition ensures consistent starts whether you're using the electric starter or kicking things old-school.
The 5-speed international transmission puts you in command of city traffic. Gear ratios are carefully spaced—from 1st at 2.909 for brisk acceleration from stops to 5th at 0.954 for relaxed highway cruising. Primary drive ratio of 3.333 paired with chain final drive transfers power smoothly to the rear wheel.
Chassis geometry is tuned for urban agility. The inverted smooth hydraulic front fork absorbs road imperfections, while the single spring rear shock maintains composure over rough pavement. With 160 mm of ground clearance and a 1370 mm wheelbase, this bike filters through traffic effortlessly while remaining stable at speed.
Braking flexibility lets you build your ideal setup—front disc brake available as optional upgrade, while rear brake comes standard as expandable shoe/drum with optional rear disc available. Roll on 110/70-17 front and 130/70-17 tires mounted on spoked wheels, with optional inverted disc aluminum wheels available for a premium look.
Standing 2010 mm long, 780 mm wide, and 1070 mm tall, the ZFYC street bike presents a sleek, modern silhouette. The 800 mm seat height accommodates a wide range of riders, making stop-and-go traffic manageable and confidence-inspiring.
Weighing 150 kg ready to ride with an equal 150 kg maximum load capacity, this bike offers balanced handling for daily commuting. Fuel tank capacity ranges from 3.5 L to 4.3 L depending on configuration, while top speed reaches 115 km/h—plenty for highway merges and weekend escapes. Climbing ability exceeds 28°, so hilly terrain won't slow you down.
Full LED lighting enhances visibility and style—the lens LED headlight delivers 15W high beam and 6W low beam with integrated 5W position light. The taillight combines driving (5W), brake (10W), and position (1.2W) functions. Front and rear dynamic LED indicators (0.6W–1W) provide modern flair while ensuring you're seen by other motorists. A maintenance-free 6MF7EL gel battery delivers reliable starts without constant attention.
The ZFYC 225cc Street Motorcycle—urban style meets everyday reliability.
