Yamaha FZ-S Fi Hybrid vs FZ-S Fi vs FZ Fi : The Yamaha FZ series has long been the benchmark for muscular street-naked motorcycles in the 150cc segment. With bold styling, everyday usability, and a reputation for reliability, the FZ family has built a loyal fan base over the years. Now, Yamaha has gone a step further by introducing the FZ-S Fi Hybrid — India’s first hybrid motorcycle in this category.
But how does this new Hybrid model compare with the standard FZ-S Fi and the entry-level FZ Fi? Is the hybrid technology worth the extra premium, or do the simpler models still make more sense? Here’s Motors77’s deep dive, with engine, dimensions, chassis, features, riding impressions, and colour options presented in a clear comparison format.
Engine & Performance
All three motorcycles use the same proven 149 cc, air-cooled, SOHC, 2-valve engine delivering 12.4 PS at 7,250 rpm and 13.3 Nm at 5,500 rpm. The real distinction lies in the Hybrid’s technology package.
The Smart Motor Generator (SMG) gives a torque assist during initial acceleration, making city rides smoother and more responsive. It also integrates with the Stop & Start System (SSS), automatically switching off the engine at traffic lights and restarting instantly when needed. This improves fuel efficiency while reducing rider fatigue.
In comparison, the FZ-S Fi and FZ Fi deliver the same power but without hybrid support. They are still smooth and refined, but lack the modern efficiency tricks of the Hybrid.

Hybrid Technology Explained
The highlight of the FZ-S Fi Hybrid is Yamaha’s use of mild-hybrid technology in the 150cc commuter space — something unique in this segment. Unlike a full-hybrid car or scooter, the FZ-S Fi Hybrid doesn’t use a separate electric motor to power the wheels. Instead, it employs a Smart Motor Generator (SMG) that plays three important roles:
- Silent Starts: The SMG replaces the traditional starter motor, cranking the engine almost noiselessly. It feels refined right from the moment you thumb the starter.
- Torque Assist: At low revs or initial acceleration, the SMG adds a small amount of torque from the battery. This means pulling away from traffic lights or overtaking at city speeds feels smoother and quicker, even though peak power remains the same as the regular FZ-S Fi.
- Stop & Start System (SSS): When you’re waiting at a signal, the engine shuts off automatically to save fuel. The moment you press the clutch or twist the throttle, the SMG silently brings it back to life. This improves fuel efficiency and cuts unnecessary idling.
The result is a bike that feels more refined and easier to live with in urban traffic. The torque assist doesn’t turn the FZ into a performance machine, but it does make commuting less stressful and more efficient. In real-world conditions, riders have reported slightly better mileage than the non-hybrid models, with fewer vibrations in stop-go situations.
Dimensions & Practicality
Yamaha has kept the overall ergonomics practical across the FZ family. All three bikes have a 790 mm seat height, making them accessible for a wide range of riders. At 138 kg, the Hybrid is slightly heavier than the standard FZ-S Fi (137 kg) and FZ Fi (134 kg), but the difference is negligible in daily use.
Dimensions Comparison
| Specification | FZ-S Fi Hybrid | FZ-S Fi | FZ Fi |
|---|---|---|---|
| Overall Length | 2,000 mm | 2,000 mm (V4.0) / 1,990 mm (V3.0) | 1,990 mm |
| Width | 780 mm | 780 mm | 780 mm |
| Height | 1,080 mm | 1,080 mm | 1,080 mm |

| Ground Clearance | 165 mm | 165 mm | 165 mm |
| Kerb Weight | 138 kg | 137 kg | 134 kg |
| Fuel Tank Capacity | 13 L | 13 L | 13 L |
Chassis & Ride Quality
The FZ series continues to be based on a lightweight, confidence-inspiring chassis with wide tyres that give it a planted stance.
Suspension duties are handled by a telescopic fork up front and a 7-step adjustable Monocross at the rear, tuned for sporty handling. While this setup is stable at higher speeds and around corners, it can feel a little firm over broken roads.
Braking is strong and predictable, with a 282 mm front disc and 220 mm rear disc, supported by single-channel ABS. The wide 140 mm radial rear tyre ensures grip and stability, especially in city corners and quick overtakes.

Features & Technology
This is the area where the Hybrid pulls ahead. It gets a TFT display, Turn-by-Turn navigation, and full Y-Connect smartphone app support. These features bring it closer to premium motorcycles while improving convenience for everyday riders.
The FZ-S Fi also offers Y-Connect on select trims, but misses the TFT screen and navigation. The base FZ Fi is the simplest of the lot — no connectivity, and even the tail-light is a traditional bulb instead of LED.

Hybrid Riding Impressions
When you ride the FZ-S Fi Hybrid, the difference is immediately noticeable in city traffic. The initial throttle response is cleaner, and the bike pulls away with less effort. While the peak power and torque numbers are identical to the non-hybrid versions, the Hybrid feels a touch livelier in the first few gears.
The Stop & Start system works seamlessly once you get used to it. At traffic signals, the bike shuts down smoothly, and with a light twist of the throttle, it restarts almost instantly. There’s no jerk or lag, which makes it practical for Indian city conditions where every second counts.
Out on open roads, the performance is still very commuter-oriented. The Hybrid is happiest between 50–80 km/h, delivering steady and relaxed cruising. Push it harder and you’ll feel the limitations of the 149cc engine — it’s not built for triple-digit speeds or sporty riding. That said, the wide tyres, stable chassis, and predictable brakes make it one of the most confidence-inspiring bikes in its segment.
In terms of ride quality, the suspension is on the firmer side. On smooth tarmac, the bike feels planted and sure-footed. However, over potholes and broken patches, you do feel the stiffness. This is consistent across all FZ models, but the Hybrid’s extra features make up for it in daily use.
The TFT display and Y-Connect app add to the modern feel. Navigation prompts, call/SMS alerts, and maintenance reminders make it stand out from the competition. Riders who spend a lot of time commuting will appreciate how these small touches improve convenience.
