KEY HIGHLIGHTS
- New sub-350cc engine (349.13cc) specifications leaked
- Expected to power Pulsar NS400Z and Dominar 400
- Output rated at 40.6 PS and 33.2 Nm; Slight drop in performance numbers
Bajaj Auto is preparing a significant shift in its performance motorcycle lineup, and it's not about adding more power; it's about smart downsizing. Fresh leaks suggest that the brand is developing a new sub-350cc engine that will soon power models like the Bajaj Pulsar NS400Z and Bajaj Dominar 400. The move is largely strategic, aimed at navigating India's evolving tax structure while keeping performance credentials intact.

Bajaj Pulsar 350cc: Why Bajaj Is Moving To Sub-350cc
The shift towards a smaller engine isn't accidental. Motorcycles exceeding 350cc fall into a higher GST bracket after the GST 2.0, which impacts pricing flexibility. By slightly reducing engine displacement of the Bajaj Pulsar NS400Z and the Dominar while maintaining almost similar output figures, Bajaj can optimise costs without drastically altering the riding experience. Interestingly, despite this mechanical change, the company is expected to continue with existing nameplates like '400', suggesting a focus on brand recall over strict numerical accuracy.
The upcoming engine is reported to displace 349.13cc, placing it just under the crucial 350cc threshold. While the bore remains unchanged at 89 mm, the stroke has been shortened, which is the primary method used to reduce displacement. Power output is expected to stand at 40.6 PS at 9,000 rpm, while peak torque is pegged at 33.2 Nm at 7,500 rpm. These figures indicate a slight dip compared to the current setup, but not enough to dramatically alter real-world performance. The engine continues to follow a familiar formula, a liquid-cooled, single-cylinder unit paired with a 6-speed gearbox. It will also retain features like a slip-and-assist clutch and a conventional lubrication system, ensuring continuity in riding dynamics.

How Different Is It From The Current Engine?
On paper, the changes appear subtle but meaningful. Compared to the existing engine, output drops marginally, by a couple of PS and Nm, while displacement reduces by around 24cc. In practical terms, this suggests that riders are unlikely to notice a drastic difference in everyday riding conditions. The focus seems to be on maintaining a similar character while improving cost efficiency from a regulatory standpoint.
Visually, both motorcycles are expected to remain unchanged. The Pulsar NS400Z and Dominar 400 will likely carry forward their current styling, colour options, and overall road presence. Feature lists are also expected to stay intact, including USD front forks, dual-channel ABS, disc brakes at both ends, riding modes, and Bluetooth-enabled instrument consoles with navigation support. This ensures that while the engine evolves, the overall package remains familiar to buyers.
Pricing & Launch Expectations
Despite the shift in engine capacity, Bajaj may choose to keep pricing close to current levels. The brand has previously absorbed cost fluctuations rather than passing them directly to customers, and a similar strategy could be adopted here. With key specifications already surfacing, an official announcement is likely not far away, and the updated models could make their debut in the coming weeks.
Verdict
Bajaj's approach with this new engine reflects a calculated balance between performance and practicality. Instead of chasing higher numbers, the brand is focusing on smarter engineering to stay competitive in a price-sensitive market. If the real-world riding experience remains close to what the current bikes offer, most buyers are unlikely to be concerned about the slight drop in displacement. With familiar styling, unchanged features and potentially stable pricing, this update could prove to be a clever move rather than a compromise, keeping the costs in check as well as the mass appeal intact, something that the Triumph 400cc bikes are also doing to retain its core essence.
