The RE Thunderbird has long been synonymous with laid-back cruiser vibes and classic Royal Enfield charm. Although the Thunderbird 350 is officially discontinued as of 2020, it continues to enjoy a loyal fan base in 2025, especially on the used-bike market. In this deep dive, we’ll explore everything a potential rider or enthusiast needs to know about the RE Thunderbird 350, from current on-road prices and real-world mileage to its top speed and curb weight. Along the way, we’ll weave in comparisons with the Thunderbird 500 and Thunderbird 650, as well as its spiritual successor, the Meteor 350.
By the end of this guide, you’ll have a comprehensive understanding of why many riders still chase the nostalgic thump of the Thunderbird 350, and whether it makes sense for you in 2025.
Discontinuation of the RE Thunderbird 350
The Royal Enfield Thunderbird 350, first introduced in 2000, quickly became a favorite among cruiser enthusiasts in India. Its 346cc, air-cooled, single-cylinder engine delivered 19.8 bhp at 5,250 rpm and 28 Nm of torque at 4,000 rpm, paired with a 5-speed gearbox. The bike’s classic design, featuring a teardrop fuel tank, chrome accents, and a low-slung stance, made it a standout in the market. Over the years, it received updates, including a 2012 facelift that introduced a projector headlamp, digital instruments, and an LED taillight, enhancing its appeal.
Despite its popularity, Royal Enfield discontinued the RE Thunderbird in 2020. This decision was driven by several factors, including stricter BS6 emission norms that required significant engine updates, as well as a shift in consumer preferences toward motorcycles with modern features such as LED lighting, advanced instrumentation, and improved fuel efficiency. The Thunderbird 350, while iconic, was starting to feel dated compared to newer models in Royal Enfield’s lineup. To meet these demands, Royal Enfield introduced the Meteor 350, a cruiser that retains the spirit of the Thunderbird while offering a more refined and contemporary riding experience.
Used Market and Last Ex-Showroom
Why There Is No New “2025 Model”
Since Royal Enfield ceased production of the Thunderbird 350 in November 2020, there are no “brand-new” 2025 units rolling off the showroom floor. Instead, the “2025 price” refers to:
- Last known ex-showroom (new) prices (FY 2020): ₹1.49–1.56 lakh.
- Current (2025) going rates on the used-bike market, which can vary significantly based on condition, year of purchase, and region.
Last Ex-Showroom Price (2020 Figures)
- Base RE Thunderbird 350 (Standard): ₹1,49,701 (ex-showroom) to ₹1,56,496 in major cities like Delhi and Mumbai.
- RE Thunderbird 350X (Sportier Variant): ₹1,56,913–₹1,63,842 (ex-showroom).
Keep in mind that these ex-showroom figures from 2020 serve as a reference point. After accounting for GST, RTO, and insurance, the on-road price likely ranged around ₹1.60 lakh to ₹1.70 lakh.
2025 Used-Bike Price Range
As of mid-2025, well-maintained Thunderbird 350s (model years 2018–2020) typically sell for ₹1.00 lakh to ₹1.60 lakh, depending on:
- Kilometers on the odometer: Lower mileage (under 15,000 km) fetches a premium.
- Maintenance history: Servicing at authorized dealerships or trusted mechanics increases resale value.
- Condition (cosmetic & mechanical): Original paint, working accessories (like panniers or crash guards), and minimal mechanical issues command higher prices.
A 2019 Thunderbird 350 with 10,000 kilometers and a spotless service record, for instance, might fetch ₹1.40 lakh in Delhi, whereas a comparable vehicle in a smaller town might fetch ₹1.20 lakh.
Engine & Performance
Engine Specifications
- Engine Type: 346 cc, single-cylinder, 4-stroke, twin-spark, air-cooled UCE.
- Max Power: 19.8 bhp @ 5250 rpm.
- Max Torque: 28 Nm @ 4000 rpm.
- Gearbox: 5-speed constant-mesh, spring-loaded wet multiplate clutch.
- Fuel Tank Capacity: 20 litres.
Real-World Mileage
- ARAI-Claimed (New): 30-35 km/kg.
- Owner-Reported (Mileage Range): 35 kmpl to 53.4 kmpl, depending on riding style and maintenance.
In practice, expect around 35 kmpl in mixed riding (city and highway). Riders who maintain their carburettor/EFI setup, keep tyre pressures in check, and avoid aggressive throttle inputs can push this closer to 40-45 kmpl, even with a heavy load.
Top Speed & Riding Character
- Top Speed: 135 kmph (claimed).
- Acceleration: 0-60 kmph in 6.5 seconds (depending on rider weight and weather).
- Riding Range: With a 20-litre tank and 35 kmpl average, you get 700 km between fill-ups.
The Thunderbird 350’s long-stroke engine churns out torque low down, making it effortless to ride under 80 kmph. However, pushing it to its top speed requires keeping the tachometer above 5000 rpm, where vibration becomes noticeable. For most riders, the “cruise sweet spot” is 80–100 kmph, where you experience minimal vibes and maximize fuel efficiency.
Weight & Ergonomics
Kerb Weight & Dimensions
| Specification | Thunderbird 350 |
|---|---|
| Kerb Weight | 197 kg |
| Seat Height | 775 mm |
| Wheelbase | 1440 mm |
| Ground Clearance | 135 mm |
| Length × Width × Height | 2090 × 735 × 1140 mm |
Handling & Ergonomics
- Riding Posture: Long distances are ideal for the calm, upright riding attitude produced by the wide, upward-swept handlebars and forward-set footpegs.
- Suspension: Twin rear shocks (with adjustable preload) and telescopic front forks are adjusted for comfort on uneven city roads and potholes.
- Brakes: 280 mm front disc with dual-piston caliper; 240 mm rear disc; dual-channel ABS on later models.
Comparison with Thunderbird 500 VS Thunderbird 650
Even if Royal Enfield’s larger cruisers were more expensive to buy and operate, the Thunderbird 350 is still the most economical entry point.
Thunderbird 500
- Engine: 499 cc vertical twin, twin-spark, air/oil-cooled.
- Max Power: 27.2 bhp @ 5250 rpm.
- Max Torque: 41.3 Nm @ 4000 rpm.
- Mileage: 25–30 kmpl (owner-reported).
- Kerb Weight: 225 kg.
- Last Ex-Showroom Price (2020): ₹2.14 lakh.
Although the Thunderbird 500 had superior mid-range power and felt more stable on highways, it was significantly more expensive and had a lower fuel economy than the 350.
Thunderbird 650 (Super Meteor)
Although never officially badged as “Thunderbird 650,” the Super Meteor 650 (released in 2023) is often viewed as a spiritual successor in the larger-cruiser segment:
- Engine: 648 cc parallel-twin, air/oil-cooled, SOHC.
- Max Power: 47 bhp @ 7250 rpm.
- Max Torque: 52 Nm @ 5250 rpm.
- Wet Weight: 216 kg.
- Fuel Capacity: 15 litres.
- On-Road Price (2025): ₹3.15 lakh (Delhi).
Unlike the Thunderbird line, the Super Meteor 650 has high-end parts, including the optional tripper navigation, slipper clutch, and ride-by-wire. Its high cost and weight, however, limit its appeal to serious cruisers or those looking for a luxurious weekend getaway.
Key Insights & Buyer Considerations
Why Choose a Thunderbird 350 in 2025?
- Classic Aesthetics: Nothing beats the timeless teardrop tank, dual-seat cruiser silhouette, and “thumper” exhaust note of the TB350.
- Affordability (Used): Compared to buying a new Meteor 350 ( ₹2.10 lakh on-road), a well-kept 350 can save you ₹40,000–₹60,000.
- Simplicity: Carburettor (or early EFI) simplifies maintenance if you prefer basic mechanical work. Parts are widely available and affordable.
- Community & Aftermarket: Strong owner groups, custom shops, and a vibrant aftermarket exist, making customization both fun and budget-friendly.
Drawbacks to Keep in Mind
- Discontinued Support: Royal Enfield’s official spares are still available, but you can’t buy a “new” Thunderbird 350. Fuel-injection service (if EFI) might be costlier than carburettor tuning.
- Ride Vibes & Refinement: Expect considerable vibration above 80 kmph. The Meteor 350’s engine feels smoother, thanks to its balancer shaft.
- Braking & Safety: While the 350X offered dual-channel ABS, earlier variants had single-channel ABS or no ABS at all. If safety is a prime concern, confirm your chosen bike has dual-channel ABS.
- Fuel Efficiency Variations: The wide mileage range (35–53 kmpl) means you need to analyze a specific bike’s service history to gauge realistic fuel costs.
