#### **Cons**

1. **High Cost of Ownership**

- **Maintenance & Repairs:** High-performance components (Ohlins suspension, carbon fiber parts, advanced electronics) can be **expensive to repair or replace**.

- **Fuel Consumption:** The **high-revving engine and aggressive riding style** lead to **poor fuel efficiency** ( 10-12 L/100km or 24-28 mpg).

2. **Aggressive Riding Required**

3. **Comfort and Practicality Issues**

- **Aftermarket exhausts can alter the bike s behavior** some riders report **increased exhaust backpressure** if not properly matched.

5. **Track Focus Limits Street Use**

While the RSV4 is **capable on the street**, its **lack of wind protection, aggressive ergonomics, and high power-to-weight ratio** make it **less practical for daily commuting or long-distance rides** compared to bikes like the **Ducati Panigale V4** or **Kawasaki Ninja ZX-10RR**.

6. **Potential Reliability Concerns**

- Aprilia s **V4 engines are known for high stress** on components due to their **high RPM and power output**.

- **Ohlins suspension and advanced electronics** can be **fragile** if not maintained properly.

- **Resale depreciation** may be faster than on more mass-market sport bikes.

7. **Noise and Legal Restrictions**

- Some regions **limit high-performance bikes** in certain zones (e.g., urban areas).
