Yamaha FZ FI vs Yamaha FZ S FI Comparison

The Yamaha FZ FI and FZ S FI are two of India's most popular 150cc streetfighter motorcycles. Both bikes have a loyal fan following and are known for their sporty performance and commuter-friendly nature. But which of these Yamaha bikes is the better choice? Let's break down the key differences.

Engine Specifications
Both bikes use the same 149cc single-cylinder fuel-injected engine. This engine produces 12 bhp of maximum power at 7,250 rpm and 13.3 Nm of peak torque at 5,500 rpm. The only difference is that the Yamaha FZ S FI gets a slightly higher compression ratio of 9.6:1 compared to 9.5:1 on the FZ FI. However, in real-world riding, there is no noticeable difference in performance between the two. Both bikes feel peppy and reach a top speed of around 110 kmph.

Mileage
Owner-reported mileage figures suggest the FZ FI has a small advantage in terms of fuel efficiency. Most FZ FI owners report an average of 45-48 kmpl, while the FZ S FI delivers around 42-45 kmpl. The FZ FI's tighter combustion chamber helps it return marginally better fuel efficiency.

Design and Features
Styling-wise, both Yamaha bikes have an aggressive streetfighter stance. The FZ S FI gets a few cosmetic upgrades like angular split headlamps and fly screen-mounted rearview mirrors. It also offers an optional aluminum grab rail. In terms of features, it gets a fully digital instrument console and single-channel ABS. Storage space is the same at 21 liters under the seat.

 
Variants and Pricing
The FZ S FI is available in two variants—Standard and Deluxe. The Standard variant costs Rs. 1.22 lakh, while the Deluxe costs Rs. 1.24 lakh (both prices, ex-showroom). The FZ FI price, on the other hand, has just a single variant priced at Rs. 1.16 lakh (ex-showroom). So, in terms of value, the FZ FI has a clear advantage of being more affordable.

Ride and Handling
When it comes to dynamics, the Yamaha FZ S FI is slightly better balanced thanks to its steeper steering angle and rear-set footpegs. This makes it more agile in city traffic. However, the difference is marginal, and both bikes handle well at high speeds on the highway, too. The braking performance from the front disc and rear drum brakes is similar.

Verdict

In summary, while the FZ S FI offers minor upgrades over the FZ FI, it is also more expensive. The FZ FI presents better value for most buyers thanks to its attractive price point and enjoyable performance. It remains one of India's top-selling 150cc commuter motorcycles for good reason. However, those seeking an even sharper ride can consider the FZ S FI. Ultimately, both are great options in the 150cc segment. So, compare bikes in India before buying any of the two to gauge the best one for you.
