Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Iconic Design and Prestige**

The RSV Mille is one of Aprilia s most legendary sport-touring bikes, known for its aggressive, angular styling and racing heritage. Owning one carries a sense of prestige and is a favorite among enthusiasts who appreciate its unique aesthetic.

2. **Rotax V990 Engine**

The Rotax V990 is a high-performance, air-cooled, 999cc V-twin engine that produces around 110 horsepower and 75 lb-ft of torque. It is a reliable powerplant when properly maintained, offering a thrilling mix of power and mid-range torque. The engine s simplicity compared to modern liquid-cooled units can also make it easier to work on for those with mechanical skills.

3. **Sport-Touring Capabilities**

The RSV Mille was designed as a sport-tourer, blending sportbike agility with long-distance comfort. It features a comfortable riding position, decent wind protection, and a sturdy frame that can handle both track days and highway cruising.

4. **Track Potential**

The bike s lightweight frame, aggressive handling, and powerful engine make it a capable track bike. Many owners modify it for racing, and its reputation in motorsport (including wins in the Supersport World Championship) adds to its appeal for performance-oriented riders.

5. **Classic Appeal**

For collectors and riders who appreciate vintage or classic bikes, the RSV Mille holds a nostalgic value. Its design is timeless, and owning one can be a passion project for those who enjoy restoring or maintaining older machinery.

6. **Potential for Modifications**

The Rotax V990 is highly tunable, with aftermarket support for upgrades like exhausts, camshafts, and fuel systems. This allows owners to tailor the bike to their preferences, whether for more power, better throttle response, or improved reliability.

7. **Resale Value (for Well-Maintained Examples)**

While not as high as modern sport-tourers, a well-documented, restored, or race-prepped RSV Mille can still hold value among enthusiasts. Some rare or modified versions may even appreciate over time.

### **Cons**

1. **Age and Wear**

The 2000 model is over two decades old, meaning the bike has likely accumulated significant mileage. Common issues include worn suspension, aging tires, and general wear on the frame, fairings, and electrical components. Rust can also be a concern, especially in regions with harsh weather.

2. **Maintenance and Reliability**

While the Rotax V990 is robust, it is not immune to wear. Older engines may suffer from carbon buildup, valve issues, or oil leaks. The lack of modern electronics (like modern fuel injection or traction control) means more manual intervention is required for tuning and troubleshooting. Owners often report that the bike requires more frequent maintenance than modern counterparts.

3. **Parts Availability and Cost**

Finding original or high-quality aftermarket parts can be challenging. While some components are still available, others may require sourcing from specialty suppliers or eBay, which can drive up costs. The thermostat housing you mentioned is a small but critical part if it s failing, replacements may not be readily available or could be expensive.

4. **Fuel and Emissions Compliance**

The RSV Mille was built for pre-EU emissions standards, and while it may not require a catalytic converter, modern fuel can sometimes cause issues with older engines. Some riders report that using higher-quality fuel or additives helps mitigate problems like carbon buildup.

5. **Safety and Modern Standards**

The bike lacks modern safety features such as ABS, traction control, or advanced rider aids. While experienced riders may not mind, this can be a concern for newer riders or those prioritizing safety. The lack of stability control can also make it more challenging to handle in slippery conditions.

6. **Comfort and Ergonomics**

While the RSV Mille is more comfortable than a pure sportbike, its riding position is still aggressive. Long rides may cause fatigue in the wrists, back, or legs, especially compared to modern sport-tourers like the Aprilia Tuono V4 or BMW S 1000 RR.

7. **Resale Market Limitations**

The market for used RSV Millies is niche. While there is a dedicated following, the pool of potential buyers is smaller than for more modern or mass-produced bikes. This can make it harder to sell if you decide to upgrade later.

8. **Noise and Vibration**

The Rotax V990 is loud, especially at higher RPMs, and the bike s frame transmits more vibration to the rider than modern, more refined engines. This can be tiring on long rides.

9. **Legal and Insurance Considerations**

Older bikes may face higher insurance premiums due to perceived higher risk or lower safety standards. Additionally, some regions have restrictions on older or modified bikes, so it s important to check local regulations.

10. **Skill and Experience Required**

The RSV Mille is not a beginner-friendly bike. Its power delivery, handling, and lack of modern aids demand a higher level of skill. Newer riders may find it intimidating or difficult to control, especially in traffic or on slippery surfaces.

### **Conclusion**

Buying a 2000 Aprilia RSV Mille with a Rotax V990 engine and thermostat housing is a decision that appeals to those who prioritize heritage, performance, and the challenge of maintaining an older machine. The bike offers a unique blend of sportbike agility and touring comfort, along with a powerful engine that remains a favorite among enthusiasts. However, the cons particularly the age-related wear, part availability, and maintenance demands cannot be overlooked.

If you are an experienced rider with mechanical skills, a passion for classic bikes, and the resources to properly maintain and restore the bike, the RSV Mille can be an incredibly rewarding project. It s ideal for those who enjoy track days, modifications, and the thrill of riding a piece of motorcycle history. On the other hand, if you prioritize modern safety features, ease of maintenance, or a broader resale market, a newer sport-tourer or a more modern sportbike might be a better fit.

### **Recommendation**

- You are an experienced rider comfortable with high-performance bikes and older machinery.

- You have access to mechanical skills or a trusted mechanic to handle maintenance and potential issues.

- You are drawn to the bike s heritage, design, and track potential, and are willing to invest time and money into restoring or modifying it.

- You plan to use it primarily for track days, short rides, or as a passion project rather than daily commuting or long-distance touring.

- You can source parts reliably and are prepared for potential costs associated with older components.

- You are a newer rider or prioritize safety and modern rider aids like ABS or traction control.

- You lack the time, budget, or mechanical knowledge to properly maintain the bike.

- You are looking for a bike with a broad resale market or low long-term ownership costs.

- You prefer modern comforts, such as ergonomics, fuel efficiency, or electronic rider assistance.

- The bike has significant unknown history (e.g., no service records, signs of neglect, or obvious wear).

If you love the RSV Mille s design but want something more modern, consider newer sport-tourers like the Aprilia Tuono V4, BMW S 1000 RR, or Ducati Multistrada V4. If you re specifically drawn to the Rotax engine, look for a newer model with a Rotax V-twin, such as the Aprilia RSV4 or the BMW S 650 GS (which uses a Rotax-based engine). For a more budget-friendly classic, a well-maintained Aprilia RSV 1000 or a Yamaha FZR 1000 could be worth exploring.

Ultimately, the RSV Mille is a fantastic bike for the right owner but it demands respect, dedication, and a willingness to embrace its quirks. If you re prepared for that, it can be an unforgettable ride. If not, there are plenty of other options that offer modern conveniences without sacrificing performance.
