### **Pros and Cons of Buying a 2020 Can-Am Defender 800 DPS 18" CDI (Model #420666864)**

#### **Pros**

1. **Versatility** The Defender 800 DPS is designed for both on-road and off-road use, making it suitable for commuting, trail riding, and light utility tasks. The 18" tires provide better off-road capability compared to smaller wheels.

2. **Powerful Engine** The 800cc liquid-cooled V-twin engine delivers strong performance, with a torquey nature that makes it capable of handling steep climbs, towing light loads, and maintaining speed on highways.

3. **Comfortable Ride** The ergonomic seating position, adjustable suspension (with optional upgrades), and long-travel shocks contribute to a smoother ride compared to many competitors. The windshield and side panels reduce wind noise at highway speeds.

4. **Utility Features** The Defender comes with a **DPS (Dual Purpose System)**, which includes a **front cargo rack, rear cargo box, and a roof rack**, allowing for practical storage of gear, tools, or camping equipment. The **CDI (Can-Am Drive Interface)** provides a more intuitive control system compared to older models.

- **TrailMaster 3.0** (optional) for advanced off-road navigation.

- **LED lighting** for better visibility.

- **Anti-lock braking system (ABS)** for improved safety.

- **Electronic traction control** to assist in slippery conditions.

- **USB charging port** for convenience.

6. **Resale Value** Can-Am Defenders hold their value relatively well, especially in the utility segment, making this a solid long-term investment.

- **Long-travel suspension kits** for rough terrain.

- **Winches** for off-road recovery.

- **Aftermarket seats** for better comfort.

- **Exhaust upgrades** for improved performance.

8. **Reliability (Compared to Competitors)** While no motorcycle is perfect, the 800cc Can-Am engine is known for durability, especially when maintained properly. The liquid cooling helps prevent overheating in demanding conditions.

9. **Two-Up Comfort** The seating position is more upright than many sport bikes, making it easier for passengers to ride comfortably, which is beneficial for long trips or utility use.

10. **Brand Reputation** Can-Am is a well-established brand in the adventure and utility segment, with a strong focus on innovation and rider experience.

#### **Cons**

1. **Weight** The Defender 800 is **heavy (around 600 650 lbs fully loaded)**, which can make maneuvering in tight spaces or parking in urban areas more difficult. It also requires more effort to lift or transport.

2. **Fuel Efficiency** With an 800cc engine, fuel economy is not exceptional. Expect **around 40 50 mpg** in mixed riding conditions, which is lower than smaller adventure bikes or scooters.

3. **Maintenance Costs** While the engine is reliable, parts and labor for Can-Am models can be **more expensive** than those for Japanese or European competitors. Independent mechanics may not be as familiar with Can-Am systems.

4. **High Initial Cost** The Defender 800 starts at a premium price (often **$12,000 $15,000 ** depending on options), which may be prohibitive for budget-conscious buyers.

5. **Complexity** The **DPS system and CDI** add layers of technology that, while user-friendly, may require some learning curve for new riders. The **automatic transmission** (if equipped) is smooth but not as engaging as a manual for some riders.

6. **Wind Noise at High Speeds** Despite the windshield, highway speeds can still be noisy, especially without optional windscreen upgrades.

7. **Limited Sport Performance** If you're looking for **high-speed agility or track capability**, the Defender is not optimized for that. It s built for **utility and adventure**, not racing.

8. **Tire Wear** The **18" tires** (while great for off-road) may wear faster than smaller wheels, increasing long-term costs.

9. **Storage Space Trade-offs** While the cargo capacity is useful, the **roof rack and side boxes** can make the bike feel top-heavy when fully loaded, affecting handling.

10. **Resale Depreciation** Like most high-end adventure bikes, the Defender may lose a significant portion of its value within the first few years unless well-maintained.
