### **Pros and Cons of Buying a Polaris RZR 800 EFI (2009 Model, Axle Guard Front Left Part #5436620-070)**
#### **Pros**
1. **Performance and Power** The RZR 800 EFI (2009) is a high-performance side-by-side with a 789cc liquid-cooled V-twin engine producing around 75 80 horsepower, capable of towing moderate loads and handling rough terrain well. Its EFI (Electronic Fuel Injection) system improves throttle response and fuel efficiency compared to carbureted models.
2. **Versatility** The RZR 800 is designed for off-road use, including trails, sand, and light rock crawling. Its articulated suspension and high ground clearance make it adaptable to various terrains.
3. **Comfort and Ergonomics** The 2009 model features a spacious cabin with adjustable seats, a windshield, and optional roof options for better weather protection. The controls are intuitive, and the seating position is ergonomic for long rides.
4. **Aftermarket Support** As a popular model, the RZR 800 has a strong aftermarket presence, offering upgrades for suspension, exhaust, lighting, and storage. Parts like the axle guard (part #5436620-070) are widely available, ensuring easy maintenance and customization.
5. **Reliability (for its age)** While not brand new, the 2009 RZR 800 is a proven design with fewer electronic failures compared to later models. Many owners report it as a durable machine if properly maintained.
6. **Resale Value** Polaris side-by-sides hold their value reasonably well, especially well-maintained examples. The RZR 800 remains a sought-after model among enthusiasts.

#### **Cons**
1. **Age and Wear** The 2009 model is nearly 15 years old, meaning it may require more frequent maintenance, including suspension rebuilds, brake upgrades, and potential engine wear. Older models are more prone to rust, especially in snowy or wet climates.
2. **Electronics and Reliability Issues** Early EFI models (including the 2009) can suffer from electronic glitches, such as throttle response problems, sensor failures, or ECU (Engine Control Unit) issues. Some owners report intermittent starting or rough idling.
3. **Fuel Efficiency** Like most high-performance ATVs, the RZR 800 is not fuel-efficient, averaging around **2 3 miles per gallon** on trails. This can add up to significant fuel costs over time.
4. **Weight** The RZR 800 is heavier than some modern UTVs, which can make it less nimble on tight trails or in tight spaces. The weight also increases fuel consumption and wear on suspension components.
5. **Noise and Vibration** The V-twin engine is loud, and the frame can transmit vibration to the rider, especially over rough terrain. This may lead to discomfort during long rides.
6. **Limited Modern Features** Compared to newer models, the 2009 RZR lacks advanced features such as:- **Touchscreen infotainment**
- **Advanced traction control**
- **Improved suspension systems (e.g., Polaris newer "Power Steering" or "Adaptive Suspension")**
- **Better fuel injection tuning for modern emissions standards**
7. **Parts and Labor Costs** While parts are available, labor costs for maintenance (e.g., suspension rebuilds, engine work) can be high, especially if done professionally. DIY repairs may require specialized tools and knowledge.
8. **Safety Concerns** Older models may lack modern safety features such as:- **Rearview cameras**
- **Advanced rollover protection**
- **Upgraded braking systems (some 2009 models have basic disc brakes)**
9. **Environmental and Legal Restrictions** Some trails or public lands have restrictions on older models due to emissions concerns. A 2009 EFI model may still meet regulations, but it s worth checking local laws.
10. **Depreciation** While it holds value, the RZR 800 has seen newer, more advanced models (e.g., RZR 900, 1000, or newer EFI upgrades) that may offer better long-term value if you plan to keep the vehicle for 10 years.
