Review TRIUMPH T140v fits BONNEVILLE 750

The Triumph Bonneville T140VNP78021 750 is a masterclass in British motorcycle engineering, blending timeless classic styling with cutting-edge performance and modern technology to create a ride that is as refined as it is exhilarating. This iconic machine represents the pinnacle of Triumph s legendary Bonneville lineage, a name synonymous with adventure, freedom, and the open road. At its heart lies a 760cc parallel-twin engine, a powerplant that has been meticulously tuned to deliver a smooth yet spirited performance, with 60 horsepower and 52 lb-ft of torque that propel the bike effortlessly through both city traffic and winding backroads. The engine s air-cooled design, paired with a six-speed transmission and a final drive via a chain, ensures a classic yet robust feel under the saddle, while the electronic fuel injection system guarantees precise throttle response and efficient fuel delivery, even under demanding conditions.

The Bonneville T140VNP78021 is not just a motorcycle; it s a statement of style and heritage, with a design that pays homage to the original Bonneville racers of the 1950s while incorporating sleek, contemporary elements. The bodywork features a classic round headlamp, a signature Triumph element that exudes nostalgia, complemented by a modern fairing that reduces wind noise and enhances aerodynamics. The fuel tank, adorned with the iconic Bonneville script and a polished chrome finish, adds a touch of elegance, while the dual-sport inspired seat and ergonomic riding position cater to both cruising comfort and the thrill of leaning into corners. The bike s overall stance is confident and commanding, with a low-slung frame and a slightly raked-out front end that invites riders to take control of the road.

Underneath the polished exterior, the T140VNP78021 is built with durability and practicality in mind. The frame is constructed from high-strength steel, providing a perfect balance of rigidity and comfort, while the suspension setup consisting of a 41mm inverted front fork and a dual-shock rear suspension absorbs imperfections in the road with ease, ensuring a smooth and engaging ride. The front disc brakes with dual 292mm rotors and four-piston calipers offer impressive stopping power, while the rear single disc brake with a 260mm rotor provides reliable modulation. The bike s tires, a 120/90-17 on the front and 160/80-17 on the rear, are designed to handle a variety of surfaces, from paved highways to gravel-lined backroads, making this Bonneville as versatile as it is versatile in appearance.

For riders who crave both style and substance, the T140VNP78021 comes equipped with a range of thoughtful features that enhance its appeal. The digital instrument cluster, mounted above the round headlamp, displays essential information such as speed, RPM, fuel level, and trip metrics in a clear, easy-to-read format, while the optional Triumph Connect telematics system can be added for advanced tracking, diagnostics, and even navigation. The bike s electrical system is robust, with a reliable battery and a well-designed wiring harness that ensures consistent performance. Additionally, the Bonneville s practicality is further emphasized by its 16-liter fuel capacity, allowing for extended rides without frequent stops, and its under-seat storage compartment, which provides a secure space for essentials like a helmet or a jacket.

Whether you re cruising along a coastal highway, exploring scenic byways, or simply enjoying a leisurely ride through town, the Triumph Bonneville T140VNP78021 750 delivers an experience that is both timeless and modern. It s a motorcycle that respects tradition while embracing innovation, offering a perfect blend of power, comfort, and character. With its classic styling, refined engineering, and the unmistakable growl of its twin-cylinder engine, the Bonneville T140VNP78021 is more than just a bike it s a piece of British motorcycle history that invites you to take the road less traveled and make every mile your own.

### **Pros and Cons of Buying a Triumph Bonneville T140V (T140VNP78021, 750cc)**

#### **Pros**

1. **Classic British Bike Design** The Bonneville retains the iconic, timeless styling of Triumph motorcycles, blending vintage aesthetics with modern engineering. Its sleek, retro-inspired bodywork makes it instantly recognizable and visually appealing.

2. **Reliable and Proven Engine** The 750cc parallel-twin engine is well-regarded for its smooth power delivery, durability, and ease of maintenance. It offers a balanced mix of torque and top-end speed, making it suitable for both cruising and light touring.

3. **Comfortable Riding Position** The T140V features a relaxed, upright seating position with a low seat height (28.7 inches), which is more accommodating for riders of average height compared to some sportier bikes. The ergonomics reduce fatigue on longer rides.

4. **Decent Fuel Efficiency** For a 750cc bike, the Bonneville offers reasonable fuel economy, averaging around **40-50 mpg** (depending on riding style), making it more practical than heavier, high-performance cruisers.

5. **Good Handling for a Cruiser** While not as nimble as a sportbike, the T140V handles better than traditional cruisers thanks to its lighter weight (around **470 lbs wet**) and slightly more modern suspension setup. It s stable at speed and responsive in corners.

6. **Aftermarket Support** Triumph s Bonneville lineup has a strong aftermarket following, with available upgrades for exhausts, suspension, handlebars, and electronics. This makes customization relatively straightforward.

7. **Comfortable for Long Rides** The bike includes features like a comfortable seat, adjustable windscreen (optional), and a relaxed riding posture, making it suitable for weekend trips or light touring.

8. **Good Sound and Vibe** The engine produces a classic, throaty exhaust note that appeals to enthusiasts who enjoy the sound of a well-tuned British twin. The overall riding experience feels refined and enjoyable.

9. **Decent Tech for the Price** The T140V includes modern features like **Triumph s Traction Control, ABS, and a digital instrument cluster**, which enhance safety and riding confidence without being overly complex.

10. **Resale Value** Triumph motorcycles, especially well-maintained Bonnevilles, hold their value reasonably well compared to some other brands, making them a solid long-term investment.

#### **Cons**

1. **Limited Power for Heavy Riders** At **750cc**, the engine is strong but not overwhelming. While it delivers **60-70 hp**, it may feel underpowered for riders over **200 lbs** or those accustomed to larger bikes (e.g., 1,200cc cruisers). Acceleration is smooth but not aggressive.

2. **Narrow Seat Width** The seat is relatively narrow, which may be uncomfortable for riders with wider hips or those who prefer a more cushioned ride. Some riders opt for aftermarket seats for better comfort.

3. **Basic Suspension** The stock suspension is adequate but not high-end. On rough roads, the ride can feel firm, and the lack of adjustable preload on the rear shock may limit tuning options.

4. **Fuel Tank Capacity** With a **4.9-gallon tank**, range is limited compared to larger bikes (e.g., Harley-Davidsons with 6 gallons). This means more frequent stops for fuel, especially on long trips.

5. **Weight Distribution** As a cruiser, the T140V has a front-heavy feel, which can make it slightly less stable at low speeds or in tight corners compared to more balanced bikes.

6. **Maintenance Costs** While the engine is reliable, Triumph parts and labor can be **more expensive than Japanese brands**. Owners should budget for regular maintenance, including chain, tires, and suspension checks.

7. **Limited Customization Options** Unlike some American cruisers, the Bonneville s bodywork is less modular, making major customizations (e.g., full fairings, custom paint) more challenging and costly.

8. **Noisy in Traffic** The engine s exhaust note is pleasant at highway speeds but can be **loud and intrusive in city traffic**, potentially drawing unwanted attention.

9. **Less Powerful Than Modern Alternatives** Compared to newer 750cc bikes (e.g., Suzuki SV650, Kawasaki Z650), the Bonneville s power delivery feels more traditional and less sporty. Riders seeking higher performance may find it underwhelming.

10. **Resale Depreciation** Like most motorcycles, the Bonneville loses value over time. While not as severe as some brands, buyers should consider this if they plan to upgrade soon.

### **Conclusion**

The **Triumph Bonneville T140V** is an excellent choice for riders who prioritize **classic styling, reliability, and a comfortable cruising experience** without the bulk of a full-fledged American cruiser. It s well-suited for **weekend rides, light touring, and city commuting**, offering a good balance of power, ergonomics, and modern features.

However, it s **not ideal** for riders seeking **high performance, heavy-duty touring, or aggressive customization**. If you re looking for something more powerful, heavier, or better equipped for long-distance travel, alternatives like the **Harley-Davidson Sportster 883, Suzuki SV650, or Yamaha Bolt** might be worth considering.

**Buy the Triumph Bonneville T140V if:**

- You love the **classic British cruiser look** and want a bike that feels timeless.

- You want **heavy-duty touring features** (e.g., wind protection, long-range fuel capacity).
