Yamaha seems to be gearing up for a fresh update to its popular streetfighter, the FZ-S FI. The upcoming Yamaha FZ-S FI Version 4.0 has recently been spotted testing on Indian roads, hinting at some exciting changes.
While the test mule looked similar to the current model in many ways, a few key updates have caught the attention of bike enthusiasts and industry watchers.

What’s New on the Horizon?
One of the most noticeable upgrades on the spotted FZ-S FI test unit is the fully digital instrument cluster. While the current version already has a digital unit, the new one appears to be larger and possibly more informative. There is strong speculation that it could support Bluetooth connectivity, similar to what Yamaha offers in its higher-end models. If true, this would allow riders to sync their smartphones for call alerts, SMS notifications, and possibly turn-by-turn navigation.
Another interesting detail is the revised switchgear, which looks more premium and modern. This could be Yamaha’s way of enhancing the overall riding experience without drastically changing the bike’s identity. The test mule also featured new mirrors and slightly updated body panels, though nothing radical was observed in terms of design overhaul.
Engine and Mechanical Setup Expected to Remain the Same
As of now, no major changes are expected in the engine department. The current 149cc air-cooled, single-cylinder engine that powers the FZ-S FI is likely to continue, delivering the same balance of fuel efficiency and urban-friendly performance. Yamaha may, however, tweak the engine slightly to improve emissions or refine performance characteristics, in line with future regulatory changes.
Suspension duties are expected to remain unchanged with telescopic forks at the front and a monoshock at the rear. Disc brakes on both ends with single-channel ABS will likely continue, maintaining the bike’s well-known braking confidence in city traffic.
Aiming to Stay Ahead in the Segment
The 150cc segment in India has seen consistent demand over the years, with new entrants and regular updates from rivals like TVS Apache RTR 160 4V and Honda Unicorn. Yamaha’s move to upgrade the FZ-S FI seems focused on staying competitive in this hot segment, especially as buyers increasingly look for tech-loaded motorcycles.
Interestingly, the test mule did not reveal any major styling shift, suggesting Yamaha may retain the muscular design language that the FZ series is known for. This makes sense, considering how popular the current design remains among urban commuters and college-goers.
When Can We Expect the Launch?
Although Yamaha hasn’t made any official announcements, test sightings typically hint at a launch window within the next few months. The FZ-S FI Version 4.0 might be unveiled around mid-2025, possibly with a slight premium in pricing owing to the added tech.
What Does This Mean for Yamaha Fans?
The Yamaha FZ series has long been considered a reliable and stylish choice for Indian bikers. The introduction of a new digital cluster, possible Bluetooth features, and refined aesthetics shows Yamaha is listening to what the market wants — modern tech without compromising on everyday practicality.
While it remains to be seen how many of these upgrades make it to the production model, one thing is clear: Yamaha isn’t resting on its laurels. The upcoming FZ-S FI 4.0 aims to blend familiarity with freshness, and that might just be what keeps it relevant in a fast-evolving market.
