I’ve seen the "350cc segment" evolve from a niche playground to a high-stakes battlefield. For years, Royal Enfield held this fort with an iron grip. But now, a strategic shift from the Hinckley-Chakan alliance (Triumph and Bajaj) is about to rewrite the rulebook.
The Tax-Induced Evolution
Experience and expertise in the Indian market tell us that pricing is the ultimate performance spec. While the Triumph Speed 400 took the market by storm with its 40 PS power, it also hit a wall: India's GST structure.
Currently, motorcycles above 350cc are hit with a 40% GST (28% base + 12% cess), whereas those 350cc and below enjoy a significantly lighter 18% tax bracket. By downsizing the 398cc TR-series engine to a sub-350cc configuration, Triumph isn’t just making a "smaller bike"—they are reclaiming nearly 22% of the price tag from the taxman to give back to the consumer.
Projected Specifications: Triumph 350cc Series
| Feature | Speed 350 (Roadster) | Scrambler 350 XC (Off-Road) |
| Engine Type | Single-cylinder, 4-stroke, Liquid-cooled, DOHC | Single-cylinder, 4-stroke, Liquid-cooled, DOHC |
| Displacement | 349 cc | 349 cc |
| Max Power (Est.) | ~28–32 bhp | ~30–32 bhp |
| Max Torque (Est.) | ~27–30 Nm | ~27–30 Nm |
| Gearbox | 6-speed manual with slipper clutch | 6-speed manual with slipper clutch |
| Kerb Weight | ~175 kg | ~190 kg |
| Seat Height | 805 mm | 835 mm |
| Wheel Setup | 17-inch alloys (Front & Rear) | 19-inch Front / 17-inch Rear |
| Fuel Capacity | 13–14 Liters | 13 Liters |
| Est. Mileage | ~35 kmpl | ~28–30 kmpl |
Precision Over Power
The upcoming Triumph 350cc range, confirmed by Bajaj Auto’s leadership for an April 2026 launch, represents a shift from "out-performing" the competition to "out-valuing" them.
The Engine Blueprint: Rather than a clean-sheet design, the 350cc mill is a derivative of the existing 398cc unit. By reducing the bore while retaining the stroke, Triumph aims to preserve the "thump" and low-end torque that Indian riders crave in the city, while sacrificing only a marginal amount of top-end horsepower (likely settling around 30-32 PS).
Price Wars 2.0
Why this matters: At this price, a Triumph becomes a viable alternative for someone looking at a top-end Pulsar or a mid-range RE. It democratizes the "Premium British" badge in a way we haven't seen before.
| Feature | Current 400 Series (Approx.) | Upcoming 350 Series (Projected) |
| GST Rate | 40% | 18% |
| Est. Price (Ex-sh) | ₹1.95L - ₹2.40L | ₹1.70L - ₹1.90L |
| Target Audience | Performance Enthusiasts | Daily Commuters & Brand Aspirants |
| Key Rival | RE Guerrilla 450, KTM 390 | RE Classic 350, Honda CB350 |
The 350cc launch isn't just about one bike. It’s about a platform. Expect a Speed 350, a Scrambler 350, and potentially a Thruxton-style Café Racer to follow.
As a journalist, I see this as the final stage of the Bajaj-Triumph marriage. They’ve proven they can build world-class machines; now they are proving they can dominate the volume game. For the Indian rider, this means more choice, better technology (liquid cooling and DOHC in a segment dominated by air-cooled SOHC engines), and a badge that carries global weight.
Gemini saiLaunch Phases & Model Timeline
The rollout is expected to happen in phases, starting with the primary roadster and followed by specialized variants:
April 2026: Core models, including the Triumph Speed 350, Speed T4 350, and Scrambler 350 XC, are slated for their market debut.
Mid-2026 (Expected June/August): The more classic-oriented Triumph Bonneville 350 is anticipated to follow as a direct rival to the Royal Enfield Classic 350.
Strategic Reason for the Date
The April 2026 launch aligns with two major industrial shifts in India:
GST Realignment: The launch allows Triumph to pivot away from the high 40% GST slab currently applied to the 400cc range (above 350cc) and move into the more competitive 18% slab for sub-350cc bikes.
Regulatory Compliance: The timeline coincides with the mandatory transition to E20 petrol and updated energy mandates in India, ensuring the new engine platform is future-proofed for the 2026-27 fiscal year.
