Yamaha FZ-S Fi Ver 4.0 Review: The Smart Urban Commuter – Tech-Loaded for the Modern Rider!

Introduction: The Yamaha FZ-S Fi Ver 4.0 marks a significant evolution in Yamaha’s highly popular FZ series, building on its strong legacy as a stylish and dependable urban streetfighter. This latest iteration elevates the commuting experience by integrating advanced safety features and smart connectivity, setting a new standard in the 150cc segment.

Priced at an ex-showroom ₹ 1,30,700/-* (as of June 2025), the FZ-S Fi Ver 4.0 retains its proven 149cc fuel-injected engine but now comes equipped with segment-leading technologies like Traction Control System (TCS) and Y-Connect Bluetooth support. Designed specifically for daily riders who prioritize a blend of tech, control, and efficiency in city riding conditions, the FZ-S Fi Ver 4.0 aims to be more than just a commuter – it’s a smart urban companion.

Advanced Tech for the Urban Jungle: Key Features of the Yamaha FZ-S Fi Ver 4.0

The Yamaha FZ-S Fi Ver 4.0 is packed with features that enhance its appeal as a safe, connected, and efficient urban motorcycle.

• 149cc Air-Cooled, Fuel-Injected Engine: At its core, the FZ-S Fi Ver 4.0 is powered by a reliable 149cc, air-cooled, 4-stroke, SOHC, 2-valve, fuel-injected engine. This motor is highly optimized for urban performance and fuel efficiency, delivering 12.4 PS (9.1 kW) @ 7,250 rpm and 13.3 Nm of torque @ 5,500 rpm. Its strong low-to-mid range torque ensures effortless navigation through city traffic.

• Traction Control System (TCS): A significant and commendable safety feature for its segment, the Traction Control System (TCS) helps prevent wheelspin, especially on slippery surfaces or during aggressive acceleration, by intelligently modulating engine power. This significantly boosts rider confidence and safety.

• Y-Connect Bluetooth Technology: The FZ-S Fi Ver 4.0 comes equipped with Y-Connect Bluetooth technology, allowing riders to connect their smartphone to the motorcycle’s digital instrument cluster. This enables features like call/SMS alerts, last parked location, fuel consumption tracking, maintenance recommendations, and more, making it a truly connected riding experience.

• Single Channel ABS with Disc Brakes: For enhanced safety, the FZ-S Fi Ver 4.0 is fitted with Single Channel ABS on its 282 mm front disc brake. A 220 mm rear disc brake provides complementary stopping power. The front ABS significantly improves braking confidence and control, especially in emergency situations.

• LED Headlamp and Taillamp: The bike features a modern and bright LED headlamp for improved visibility during night rides and an updated aesthetic. The LED taillamp further completes the contemporary lighting package.

• E20 Fuel Compatibility: The FZ-S Fi Ver 4.0 is designed to be E20 fuel compatible, meaning it can run on petrol blended with up to 20% ethanol. This aligns with environmental initiatives and offers potentially enhanced fuel efficiency.

• Side Stand Engine Cut-Off Switch: A crucial safety feature, the side stand engine cut-off switch prevents the engine from starting or automatically kills it if the side stand is down, reducing the risk of accidental falls.

• Lightweight and City-Friendly Design: With a kerb weight of 136 kg, the FZ-S Fi Ver 4.0 maintains its signature lightweight and agile character, making it easy to maneuver through congested city traffic and park in tight spaces.

The Riding Experience: Pros and Cons for the Modern Urban Rider

The Yamaha FZ-S Fi Ver 4.0 aims to set itself apart with its blend of tech and practicality, making it a compelling option.

✔️ Pros: Why the Yamaha FZ-S Fi Ver 4.0 Excels

• Loaded with Advanced Tech (TCS & Y-Connect): The inclusion of a Traction Control System (TCS) and Y-Connect Bluetooth connectivity makes the FZ-S Fi Ver 4.0 one of the most technologically advanced bikes in its 150cc segment. TCS significantly enhances safety, while Y-Connect provides smart features and convenience.
• Great for City Commuting: Its refined 149cc fuel-injected engine, lightweight chassis (136 kg), and comfortable ergonomics make it exceptionally well-suited for navigating congested city traffic with ease and comfort.
• Efficient and Eco-Friendly (E20 Compatible): The engine is highly fuel-efficient for urban conditions, and its E20 fuel compatibility aligns with modern environmental standards, offering a greener ride.
• Stylish LED Lighting: The updated LED headlamp and taillamp not only enhance visibility and safety but also give the bike a more modern and premium aesthetic compared to previous versions.
• Excellent Fuel Efficiency: The FZ-S Fi Ver 4.0 continues the FZ series’ reputation for delivering very good mileage, making it an economical choice for daily riders.
• Reliable Yamaha Engineering: Backed by Yamaha’s long-standing reputation for reliability and build quality, offering peace of mind to owners.
• Comfortable Riding Posture: The upright ergonomics ensure a comfortable ride for both short and long commutes, reducing rider fatigue.

❌ Cons: Points for Consideration

• No Dual-Channel ABS: While it features single-channel ABS on the front wheel, the absence of dual-channel ABS means the rear wheel remains susceptible to locking under hard braking, a feature present in some slightly higher-segment or premium competitors.
• Lacks Performance for Highway Touring: The 12.4 PS engine, while excellent for city traffic and fuel efficiency, might feel slightly underpowered for extended highway cruising, especially at higher speeds or with a pillion, compared to more powerful 160cc rivals.
• No Navigation in Cluster: While Y-Connect offers last parked location and other features, the digital instrument cluster itself does not provide integrated turn-by-turn navigation directly on screen, which some more advanced TFT displays now offer.
• Gear Position Not Displayed: The absence of a gear position indicator on the digital console can be a minor inconvenience for new riders or those who prefer to know the engaged gear at a glance.
• Basic Digital Display: While functional and Bluetooth-enabled, the digital instrument cluster is still a basic LCD and not a full-color TFT unit, which some rivals or higher-segment bikes might offer for a more premium visual experience.
• No USB Charging Port: Unlike the FZ-X, this model does not explicitly mention an integrated USB charging port, which is a convenient feature for modern riders to charge their devices.

Final Verdict: The Yamaha FZ-S Fi Ver 4.0 – The Smart Choice for Urban Commuting

The Yamaha FZ-S Fi Ver 4.0 confidently asserts its position in the 150cc commuter category by masterfully blending fuel efficiency, cutting-edge safety features, and smart connectivity with its established stylish design. It’s an ideal choice for city riders who truly appreciate innovation, enhanced control, and dependable performance on every ride.

The inclusion of Traction Control System (TCS) and Y-Connect Bluetooth technology are significant upgrades that differentiate it from many competitors, offering a level of safety and convenience previously unseen in this segment. While it may not be the most powerful bike for highway touring or boast dual-channel ABS, its strengths lie in its city-friendly agility, excellent mileage, modern LED lighting, and the peace of mind offered by TCS. The Yamaha FZ-S Fi Ver 4.0 is a testament to Yamaha’s commitment to delivering a well-rounded, technologically advanced, and highly practical motorcycle for the evolving needs of the modern Indian rider.
