Review KAWASAKI Black Rear Wheel Rim Brake Rotor And Tire fits NINJA EX400 400 2018–2023

The **Kawasaki Ninja EX400 (Part Number: 41073-0938-QT)** is a meticulously engineered, high-performance rear wheel assembly designed exclusively for the 2018 through 2023 model years of Kawasaki s iconic EX400 sport-touring motorcycle. This precision-crafted package includes a **high-performance rim, disc brake rotor, and tire**, all engineered to deliver an optimal balance of braking efficiency, durability, and ride comfort. The **rim** is constructed from lightweight yet ultra-strong aluminum alloy, featuring a sleek, aerodynamic design that not only enhances the bike s aggressive yet refined aesthetic but also minimizes rotational mass for improved handling responsiveness. The **disc brake rotor**, likely a floating or drilled variant depending on the specific model year, is engineered to dissipate heat rapidly while maintaining consistent braking power under aggressive use, ensuring reliable stopping performance even during spirited riding sessions. Paired with this is a **high-quality tire** from Kawasaki s trusted lineup, optimized for the EX400 s sport-touring versatility. This tire combines a durable, long-lasting tread compound with precise grip characteristics, offering exceptional traction on both paved roads and light off-road terrain, making it ideal for riders who seek a blend of urban agility and occasional adventure. Whether cruising through city streets or navigating winding backroads, this rear wheel assembly ensures a seamless, confident riding experience, reinforcing the Ninja EX400 s reputation as a versatile and capable two-wheeled companion.

### **Pros and Cons of Buying a Kawasaki Ninja EX400 (2018 2023) with Rear Wheel Rim Brake, Rotor, and Tire**

1. **Affordability and Value** The Ninja EX400 is one of the most budget-friendly sportbikes available, making it an excellent entry into the world of performance motorcycles. Its low cost of ownership, including maintenance and insurance, is a major advantage for new riders or those on a tight budget.

2. **Lightweight and Maneuverable** Weighing around **200 210 kg (wet)**, the EX400 is easy to handle, especially in urban environments or tight parking spaces. Its compact size makes it ideal for commuting, street riding, and urban exploration.

3. **Rear Rim Brake System** While not as common as disc brakes on the front, the rear rim brake (often paired with a small rotor) provides decent stopping power in a lightweight package. It reduces weight compared to a full disc brake setup, improving agility without sacrificing too much braking performance.

4. **Fuel Efficiency** The 399cc parallel-twin engine delivers **good fuel economy**, typically around **3.5 4.5 L/100 km**, making it cost-effective for daily riding. This is particularly useful for commuters who rely on the bike for regular use.

5. **Simple and Reliable Engine** Kawasaki s parallel-twin engine is known for its **durability and ease of maintenance**. The EX400 s engine is straightforward, with fewer complex components compared to larger sportbikes, reducing long-term repair costs.

6. **Easy to Modify and Upgrade** The bike s simplicity allows for **DIY modifications**, such as exhaust upgrades, suspension tweaks, or throttle response enhancements. Aftermarket parts are widely available, making customization accessible.

7. **Good for Learning** The EX400 s **moderate power delivery (around 37 39 hp)** is suitable for new riders learning to control a sportbike. It s not overwhelming like a 600cc or larger bike, reducing the risk of accidents during the learning phase.

8. **Compact Storage and Portability** Its small size means it can be easily stored in garages, parking lots, or even taken on public transport if needed. Some models may also fold or have removable seats for added convenience.

9. **Minimalist Design** The EX400 has a **clean, no-frills aesthetic** that appeals to riders who prefer functionality over flashy styling. It s also less likely to attract theft compared to more expensive bikes.

10. **Resale Value** Due to its popularity and reliability, the EX400 holds its value reasonably well compared to other budget bikes, making it a smart long-term investment.

1. **Limited Power for Serious Sport Riding** At **37 39 hp**, the EX400 is **underpowered for aggressive sport riding, track use, or carrying passengers**. It struggles with high-speed stability and cornering compared to larger sportbikes.

2. **Weak Rear Rim Brake** While the rear rim brake is lightweight, it **provides minimal stopping power** compared to a disc brake. This can be dangerous in emergency stops, especially at higher speeds. Some riders may need to rely heavily on the front brake, which can lead to uneven tire wear.

3. **Poor High-Speed Stability** The bike s **lightweight and narrow wheelbase** make it **uncomfortable and unstable at high speeds** (above 100 120 km/h). Wind resistance and lack of aerodynamic fairings make long-distance highway riding less enjoyable.

4. **Basic Suspension** The stock suspension is **stiff and not well-tuned for comfort**, leading to a **harsh ride quality** on rough roads. Upgrading forks and shocks is often necessary for a smoother experience.

5. **Limited Comfort for Long Rides** The **small seat, minimal wind protection, and upright riding position** make the EX400 **uncomfortable for extended trips**. It s best suited for short commutes rather than touring.

6. **No ABS (Anti-lock Braking System)** Unlike many modern bikes, the EX400 lacks **ABS**, which can be a safety concern, especially for inexperienced riders. ABS helps prevent wheel lockup during hard braking, reducing skidding risks.

7. **Basic Instrumentation** The stock display is **simple and lacks advanced features** such as a digital speedometer, trip meters, or Bluetooth connectivity. Upgrading requires aftermarket solutions.

8. **Narrow Tire Options** The stock **120/70-17 rear tire** is **not ideal for aggressive riding** and may wear out quickly on rough surfaces. Wider or more aggressive tires would improve grip but may reduce fuel efficiency.

9. **Limited Aftermarket Support** While modifications are possible, the **EX400 has fewer aftermarket parts** compared to larger Kawasaki models (e.g., Ninja 400 or Z400). Some upgrades (e.g., exhausts, handlebars) may require custom fabrication.

10. **Not Ideal for Winter or Wet Conditions** The **lack of traction aids (like slipper clutches or traction control)** and the rim brake make it **less suitable for wet or slippery roads**. Riders in rainy climates may struggle with control.
