### Pros and Cons of Buying a 2019 Kawasaki Ninja 400 EX400 with the Specified Rear Axle (Part Number: 2206890)

#### **Pros**

1. **Reliability and Performance** The Kawasaki Ninja 400 EX400 is a well-regarded sportbike known for its lightweight design, responsive handling, and efficient 399cc parallel-twin engine. The EX400 variant includes additional features like a rear disc brake and a more practical riding position compared to the standard Ninja 400.

2. **Cost-Effective Ownership** As a smaller displacement bike, fuel costs are lower compared to larger engines, and maintenance is generally affordable. The Ninja 400 is also known for its durability, meaning fewer long-term repair expenses.

3. **Versatility** The EX400 s slightly more upright riding position and additional braking make it suitable for both track days and daily commuting, appealing to riders who want a bike that can handle various conditions.

4. **Aftermarket Support** The Ninja 400 has a strong aftermarket presence, with available upgrades for suspension, brakes, exhaust, and performance tuning. This allows owners to customize the bike to their preferences.

5. **Fuel Efficiency** The 400cc engine delivers good fuel economy, typically around 120 150 mpg (depending on riding style), making it ideal for short trips and urban riding.

6. **Lightweight and Maneuverable** Weighing around 350 370 lbs (depending on configuration), the Ninja 400 is easy to handle, making it accessible for riders of varying skill levels, including beginners.

7. **Resale Value** Kawasaki motorcycles generally hold their value well, and the Ninja 400 remains a popular used bike, so resale potential is decent if you decide to upgrade later.

8. **Rear Axle Compatibility** The specified rear axle (2206890) is an OEM part, ensuring a proper fit and alignment. Using genuine parts can improve longevity and reduce the risk of premature wear or failure.

#### **Cons**

1. **Limited Power for Some Riders** At 399cc, the engine produces around 44 hp and 27 lb-ft of torque, which may feel underpowered for aggressive riders or those accustomed to larger bikes. While sufficient for city and light highway riding, it may not satisfy those seeking higher performance.

2. **Basic Suspension** The stock suspension is adequate but not high-end. Riders who frequently hit rough roads or prefer a sportier feel may need to upgrade to aftermarket components for better comfort and control.

3. **Single Disc Front Brake (Standard Models)** While the EX400 includes a rear disc brake, the standard Ninja 400 comes with a single front disc. This can be limiting in high-speed braking scenarios, though the EX400 s upgrade helps mitigate this.

4. **Narrow Tire Options** The stock tires are not as aggressive as those on larger sportbikes, which may affect grip in wet or high-performance riding conditions. Upgrading to sportier tires can improve handling but may reduce comfort.

5. **Noise and Vibration** The parallel-twin engine can be noisy, particularly at higher RPMs, and some riders report noticeable vibration at certain speeds, which may require an exhaust upgrade or vibration dampeners.

6. **Limited Storage** Like many sportbikes, the Ninja 400 lacks significant storage space. Riders who frequently carry gear may need to invest in aftermarket saddlebags or a top case.

7. **Rear Axle Wear Concerns** While the specified axle is OEM, rear axles on sportbikes can wear out over time, especially if the bike is ridden aggressively or if the suspension is poorly maintained. Regular inspections are recommended to avoid unexpected failures.

8. **Depreciation Over Time** Like most motorcycles, the Ninja 400 loses value quickly after purchase. If you plan to keep the bike long-term, depreciation may be a consideration, though it remains a practical and affordable option.

### **Conclusion**

The 2019 Kawasaki Ninja 400 EX400 with the specified rear axle (2206890) is a solid choice for riders seeking a lightweight, fuel-efficient, and versatile sportbike. Its strengths lie in its reliability, ease of handling, and suitability for urban and light highway use. The EX400 s additional features, such as the rear disc brake, enhance its practicality without sacrificing sporty performance.

However, its limitations such as modest power output, basic suspension, and limited braking may not appeal to riders looking for high-performance or long-distance capabilities. If you prioritize affordability, maneuverability, and a bike that can handle daily commuting and light track use, the Ninja 400 EX400 is an excellent option. For riders who demand more power or advanced suspension, a larger sportbike or a more premium model may be preferable.

### **Recommendation**

**Buy the 2019 Kawasaki Ninja 400 EX400 with the specified rear axle if:**

- You are a beginner or intermediate rider looking for an affordable, easy-to-handle sportbike.

- You prioritize fuel efficiency, lightweight maneuverability, and practicality for city riding.

- You plan to invest in aftermarket upgrades (tires, suspension, exhaust) to enhance performance and comfort.

- You value Kawasaki s reliability and the bike s strong resale value.

**Consider alternatives if:**

- You require more power or high-performance handling, in which case a larger sportbike (e.g., Yamaha MT-07, Honda CBR600RR) or a more advanced model may be better.

- You frequently ride on rough roads or in extreme conditions, as the stock suspension may not suffice without upgrades.

- You need significant storage or long-distance comfort, as the Ninja 400 s basic features may fall short.

For most riders seeking a balance of affordability, fun, and practicality, the Ninja 400 EX400 remains a highly recommended purchase. Ensure you inspect the rear axle and overall condition of the bike thoroughly before finalizing the purchase to avoid potential issues.
