### **Pros and Cons of Buying a Triumph Thunderbird 1600/1700 (T2045691 or T2045692)**

#### **Pros**

1. **Performance and Power**

The Thunderbird 1600/1700 is a high-performance naked bike with a liquid-cooled, inline-triple engine producing **160 170 horsepower**, depending on the model. This makes it one of the fastest naked bikes in its class, offering thrilling acceleration and top-end speed.

2. **Modern Engine and Technology**

The engine features **fuel injection, variable valve timing, and a 6-speed transmission**, ensuring smooth power delivery and efficient performance. The **T2045692 (1700 model)** has a slightly detuned version of the same engine, making it slightly more refined for daily riding.

3. **Lightweight and Agile Handling**

At around **190 200 kg (wet weight)**, the Thunderbird is relatively light for its power, contributing to sharp handling and nimble cornering. The **bottom leg (T2045692)** has a slightly revised frame for better ergonomics and stability.

4. **Comfortable and Sporty Ergonomics**

The riding position is **upright yet sporty**, making it suitable for both long-distance touring and track-day riding. The **T2045692 (bottom leg)** features a slightly more relaxed seat and handlebar position, improving comfort on longer rides.

5. **High-Quality Build and Materials**

Triumph uses **high-grade aluminum frame, carbon fiber components (e.g., seat, fairings), and premium suspension (WP XACT forks and rear shock)**. The build quality is excellent, with attention to detail in fit and finish.

6. **Customization Potential**

The Thunderbird s design is modular, allowing for easy upgrades aftermarket exhausts, suspension, and handling kits are widely available. The **T2045692** also supports optional **windscreen and luggage mounts** for touring setups.

7. **Strong Aftermarket Support**

As a popular bike, parts, mods, and tuning options are readily available. The **T2045691 (1600)** has a slightly more aggressive tuning potential, while the **T2045692 (1700)** is more street-friendly.

8. **Good Fuel Economy (For a Sport Bike)**

Despite its power, the Thunderbird achieves **around 15 18 km/l (10 12 mpg)** in mixed riding, which is decent for a high-performance naked bike.

9. **Resale Value**

Triumph bikes hold their value well, especially well-maintained examples. The Thunderbird is a sought-after model, so a clean one should retain value over time.

10. **Brand Reputation**

Triumph has a strong reputation for **reliability, customer service, and innovation**, making it a trusted choice for enthusiasts.

---

#### **Cons**

1. **High Cost of Ownership**

- **Purchase Price:** New models start around ** 12,000 14,000**, and used examples can still be expensive.

- **Maintenance & Repairs:** As a high-performance bike, servicing (valve adjustments, chain tensioning, etc.) can be costly. Triumph dealerships charge premium rates for official work.

- **Tires & Consumables:** High-performance tires (e.g., Michelin Power 4, Pirelli Diablo Rosso) are expensive.

2. **Fuel Consumption**

While better than most sport bikes, the Thunderbird still drinks fuel expect to fill up **every 200 250 km** in aggressive riding.

3. **Weight (Despite Being Light for a Sport Bike)**

At **190 200 kg**, it s heavier than some competitors (e.g., Yamaha MT-09), which can make it feel sluggish at low speeds and in tight urban maneuvering.

4. **Ride Quality on Rough Roads**

The **WP XACT suspension** is excellent for sport riding but can feel **stiff on bad roads**. Upgrading to aftermarket suspension (e.g., hlins, Showa) improves comfort but adds cost.

5. **Wind Noise at High Speeds**

The Thunderbird is **not a windscreen bike**, so at **120 km/h**, wind noise becomes noticeable. Optional windscreen kits exist but are not factory-installed.

6. **Maintenance Intensity**

The **triple-cylinder engine** requires more frequent **valve adjustments (every 12,000 15,000 km)** compared to single-cylinder bikes. Neglecting this can lead to **knocking and engine damage**.

7. **Limited Comfort for Long Distances**

While better than a sport bike, the Thunderbird is **not a touring machine**. The seat and wind protection are minimal, making long rides less comfortable without modifications.

8. **Resale Depreciation (Compared to Touring Bikes)**

While it holds value better than most sport bikes, it may not appreciate as much as **adventure or touring bikes** over time.

9. **Noise and Vibration**

The **triple-cylinder engine** can be **loud and vibration-prone at idle**, though this smooths out at higher RPMs. Some riders find it intrusive in city traffic.

10. **Limited Aftermarket Fairings**

Unlike some Triumph models (e.g., Bonneville), the Thunderbird has **fewer aftermarket fairing options**, limiting customization for a more streamlined look.
