Review TRIUMPH Original Primary Cover fits T120 TR6 650

The Triumph 57-1727 650 T120 TR6 Cover is a meticulously crafted, high-performance motorcycle windscreen designed to elevate the riding experience of the iconic Triumph Bonneville T120 and TR6 models. Engineered with precision, this windscreen features a sleek, aerodynamic profile that not only enhances visibility and protection from the elements but also contributes to a more refined and aggressive stance. Constructed from high-quality, impact-resistant polycarbonate, the cover is built to withstand the rigors of daily riding while maintaining optical clarity, ensuring riders maintain optimal forward vision even at high speeds. The design incorporates a low-profile, slightly angled shape that minimizes wind turbulence, reducing fatigue and improving stability on long journeys. Its robust mounting system, featuring secure clamps and adjustable brackets, guarantees a snug and vibration-free fit, preventing any unwanted rattles or misalignments. Whether cruising along scenic routes or tackling urban commutes, this windscreen transforms the riding position into one of confidence and control, making it an essential accessory for enthusiasts who demand both style and functionality. The 650 T120 TR6 Cover is not merely an aftermarket addition it s a statement piece that complements the timeless elegance of the Triumph, blending heritage with modern performance.

### **Pros and Cons of Buying a Triumph 57-1727 650 T120 TR6 Cover**

1. **Classic Design with Modern Appeal** The Triumph T120 retains the timeless styling of the original 650cc Triumph Bonneville while incorporating modern engineering refinements. Its aggressive yet elegant look makes it stand out on the road.

2. **Reliable and Proven Engine** The 650cc parallel-twin engine is well-regarded for its smooth power delivery, durability, and ease of maintenance. It s a proven design with a strong aftermarket support network.

3. **Comfortable and Practical Ride** The T120 features a low seat height, ergonomic controls, and a comfortable riding position, making it suitable for both long-distance touring and city riding. The windscreen and fairing provide decent wind protection.

4. **Good Performance for Its Class** The engine produces around **50-55 hp** and **50-55 lb-ft of torque**, offering a balanced mix of throttle response and cruising capability. It s not a high-revving sportbike but is more than adequate for highway speeds and relaxed touring.

5. **Fuel Efficiency** Compared to larger displacement bikes, the 650cc engine achieves reasonable fuel economy, typically around **40-50 mpg**, making it cost-effective for daily use.

6. **Affordable Maintenance Costs** As a mid-sized bike, parts and servicing are generally cheaper than those for larger displacement motorcycles. The engine s simplicity also means fewer potential failure points.

7. **Strong Aftermarket Support** Triumph s 650cc platform has been around for years, ensuring a wide availability of aftermarket accessories, upgrades, and tuning options. Customization is relatively straightforward.

8. **Good Handling for a Touring Bike** While not a sportbike, the T120 handles well for its size, with a stable chassis and responsive steering. It s more nimble than traditional cruisers but still comfortable for highway riding.

9. **Resale Value** Triumph s reputation for quality and the bike s popularity contribute to a decent resale market, though this can vary based on model year and condition.

10. **Versatility** The T120 can be used for commuting, weekend rides, and even light touring, making it a practical choice for riders who want a single bike for multiple purposes.

---

1. **Outdated Technology Compared to Modern Bikes** The T120 lacks advanced features found on newer motorcycles, such as **traction control, ABS (though some models have it), or electronic suspension**. This means less safety and comfort refinement.

2. **Limited Power for High-Speed or Sporty Riding** While adequate for cruising, the engine struggles to keep up with larger bikes (e.g., 1200cc cruisers or sport-tourers) at high speeds or when overtaking. It s not a bike for aggressive riding.

3. **Vibration at Higher Speeds** The parallel-twin engine can transmit noticeable vibrations through the seat and handlebars, especially at sustained highway speeds. This can lead to fatigue on long rides.

4. **Basic Ergonomics** While the riding position is comfortable, some riders may find the handlebars and footpegs less adjustable than on modern bikes. The stock seat can also be firm for long-distance comfort.

5. **Reliability Concerns with Older Models** If purchasing a used T120, ensure it has been well-maintained. Older models (pre-2015) may have **timing chain stretch issues, carburetor problems (if not converted to fuel injection), or suspension wear**, which can add to maintenance costs.

6. **Limited Storage Space** The bike s fairing provides minimal storage, with only a small top case and no integrated saddlebags. Riders who need significant storage for long trips may need to add aftermarket bags.

7. **Noise Levels** The engine and exhaust can be quite loud, especially at higher RPMs, which may not be ideal for city riding or quiet areas.

8. **Higher Running Costs Than Smaller Bikes** While cheaper than larger bikes, the 650cc engine consumes more fuel and oil than a 300cc or 500cc bike, and maintenance intervals (e.g., valve adjustments) can add up over time.

9. **Resale Depreciation** Like most motorcycles, the T120 loses value over time. If you plan to sell it later, the depreciation may not fully offset the initial purchase cost.

10. **Limited Modern Safety Features** Without options like **angle-sensitive ABS, cornering ABS, or advanced rider aids**, the T120 feels less equipped for modern safety standards compared to newer Triumph models (e.g., the Tiger 900 or Bonneville Speed).

---

The Triumph 57-1727 650 T120 TR6 Cover is a **great choice for riders who prioritize classic styling, reliability, and a balance of comfort and performance** without the complexity or cost of a larger bike. It excels as a **daily commuter, weekend cruiser, or light touring motorcycle**, especially for those who enjoy the Bonneville aesthetic and don t need extreme power or cutting-edge technology.

However, if you re looking for **modern safety features, higher performance, or advanced ergonomics**, you may find newer models (e.g., Triumph s 1200cc range or other brands like Honda Gold Wing or Yamaha FJR1300) more suitable. The T120 is also **not ideal for aggressive riding or long-distance touring** without modifications.

---
