#### **Cons**
1. **Age and Wear** A 2001 model is **23 years old**, meaning it will require significant maintenance if not already well-cared-for. Common wear items include:
- **Tires** (likely needing replacement)
- **Brakes** (disc pads, rotors, and calipers may be worn)
- **Chain & Sprockets** (will need lubrication and possible replacement)
- **Suspension** (shock absorbers and forks may be stiff or leaking)
- **Electrical System** (old wiring, faulty switches, or battery issues)
2. **High Maintenance Costs** Ducati parts, especially for older models, can be expensive. Owners should budget for:- **Regular oil changes** (synthetic oil recommended)
- **Valve adjustments** (every 10,000 km or as needed)
- **Timing belt replacement** (if not already done critical for L-twin engines)
- **Exhaust upgrades** (if stock mufflers are too loud or restrictive)
3. **Comfort Limitations** The Monster S4 is **not designed for long-distance comfort**. The upright riding position, hard seat, and minimal wind protection make it unsuitable for extended tours. Riders with back or wrist issues may find it uncomfortable.
4. **Poor Weather Suitability** Without a full fairing, the bike offers **no protection from wind, rain, or cold**. Riders must wear full gear and accept that long rides in bad weather will be less enjoyable.
5. **Rust and Corrosion Risks** Older Ducatis, especially those exposed to wet conditions, can suffer from **frame rust** (common in the lower swingarm area) and corroded fasteners. A thorough inspection is essential.
6. **Stock Suspension is Basic** The original **WP suspension** is adequate but lacks modern adjustability. Many owners upgrade to aftermarket shocks (e.g., hlins, YSS) for better damping and comfort.
7. **Resale Value is Low** Unlike newer Ducatis, the Monster S4 does not hold its value well. If you plan to sell later, expect a depreciated price unless it s in excellent condition.
8. **Noise and Vibration** The stock exhaust is **loud** (around **95-100 dB**), which may not be ideal for urban riding. The engine also has a **distinctive, rough idle** that some find annoying. Vibration levels are moderate but noticeable at higher RPMs.
9. **Limited Modern Tech** Unlike newer Ducatis, the S4 lacks features such as:- **Traction Control**
- **ABS (unless aftermarket installed)**
- **Digital dash (stock analog gauge is basic)**
- **Modern fuel injection refinements**
10. **Finding a Reliable Example is Difficult** Many Monster S4s have been neglected, leading to **hidden mechanical issues**. Buyers must be prepared for a **thorough inspection** or a **restoration project**.
