The Yamaha FZ Fi and its naked sibling FZ S Fi Ver 4.0 deliver a refined 150cc commuter experience, combining efficient performance and modern tech. Powered by a 149cc fuel-injected SOHC engine, it produces 12.4 PS and 13.3 Nm, mated to a smooth 5-speed gearbox. Its lightweight diamond frame (≈136 kg), telescopic front fork, and mono-shock rear suspension ensure agile city maneuverability.
Braking is dependable thanks to a 282 mm front disc with ABS and a 220 mm rear disc. The full LED lighting and a vibrant 4.2″ TFT display with Bluetooth functionality elevate the ride interface. The DLX trim enhances control with traction control. A side-stand cut-off switch enhances safety, while the 13-liter tank (E20 compatible) supports claimed mileage of 60 km/l. With a low seat height of 790 mm and an aggressive streetfighter design, the Ver 4.0 versions strike a stylish, practical, and efficient balance for discerning urban riders.
