The **integrated suspension system** a hallmark of the Switchback s legendary handling relies on this crank arm to maintain consistent torque delivery while absorbing the harsh impacts of uneven surfaces, reducing fatigue on both the rider and the machine.

Built to the exact specifications of the **2019, 2020, and 2021 model years**, this aftermarket or replacement part is a direct-fit solution for riders seeking to restore or upgrade their Switchback s performance, offering the same level of reliability and precision as the original equipment.

### **Pros and Cons of Buying a Polaris 1543872-067 850 Switchback XCR AXYS 600/800 (2019 2021) Suspension Crank Arm**

#### **Pros**

1. **Reliability and Durability** Polaris is known for building robust, long-lasting ATVs, especially in the Switchback XCR lineup. The 850cc engine provides strong torque and performance, making it suitable for off-road adventures, trail riding, and light utility work.

2. **Versatility** The AXYS 600/800 suspension system offers adjustable damping, allowing riders to fine-tune the ride for different terrains (rocky trails, sand, mud, or pavement). This adaptability enhances comfort and control in varied conditions.

3. **Comfortable Seating and Ergonomics** The Switchback XCR features a low-slung seat, upright riding position, and wide footpegs, reducing fatigue on long rides. The ergonomic design is particularly beneficial for riders who prioritize comfort over aggressive off-roading.

4. **Rear-Wheel Drive (RWD) Advantages** Unlike four-wheel-drive (4WD) models, the RWD configuration simplifies maintenance (no transfer case) and improves fuel efficiency. It also excels in loose terrain where 4WD might bog down.

5. **Modularity and Upgrade Potential** The AXYS suspension is upgradeable, and the Switchback platform allows for aftermarket modifications (e.g., exhaust, tires, or lighting). This makes it a good choice for riders who want to customize their ATV over time.

6. **Good Fuel Economy for Its Class** Compared to larger 4WD ATVs, the 850cc RWD model consumes less fuel, making it cost-effective for daily use or weekend adventures.

7. **Resale Value** Polaris ATVs generally hold their value well, and the Switchback XCR, being a popular model, retains decent resale worth if maintained properly.

8. **Smooth Power Delivery** The 850cc engine provides a balanced power band, making it suitable for both cruising and light trail riding without being overly aggressive.

9. **Lower Maintenance Costs (vs. 4WD Models)** Without a transfer case or complex drivetrain, maintenance is simpler and less expensive than on 4WD ATVs.

10. **Great for Beginners and Intermediate Riders** The forgiving suspension and manageable power make it accessible for new riders while still offering enough capability for experienced off-road enthusiasts.

#### **Cons**

1. **Limited Off-Road Capability Compared to 4WD Models** While the AXYS suspension helps, the RWD configuration struggles in deep mud, steep climbs, or extreme terrain where 4WD would be more capable. It s better suited for trails and light utility rather than heavy-duty off-roading.

2. **Narrow Tire Options** The stock tires may not be optimal for all conditions (e.g., aggressive knobs for rock crawling or smooth treads for pavement). Aftermarket tires can improve performance but add cost.

3. **Suspension Tuning Can Be Tricky** The AXYS system is adjustable, but improper settings can lead to a harsh ride or poor handling. Riders need to experiment to find the right balance.

4. **Weight Considerations** At around **700 750 lbs**, the Switchback is heavier than some sportier ATVs, which can affect maneuverability in tight spaces or on technical trails.

5. **Resale Depreciation** Like most ATVs, the Switchback loses value quickly after purchase. If you plan to upgrade soon, the depreciation may offset initial savings.

6. **Limited Aftermarket Support (vs. Sport ATVs)** While the Switchback is modular, it doesn t have the extensive aftermarket parts ecosystem of sport ATVs like the Polaris RZR or Can-Am Maverick.

7. **Fuel and Oil Consumption** The 850cc engine drinks more fuel than smaller ATVs, and oil changes are necessary every **50 hours** (or as recommended), adding to maintenance costs.

8. **Not Ideal for Heavy Hauling** Unlike utility ATVs (e.g., Polaris Ranger), the Switchback is not designed for carrying heavy loads or pulling trailers. Its focus is on comfort and trail riding.

9. **Potential for Suspension Wear Over Time** The AXYS system, while durable, can wear out with heavy use, especially if not properly maintained. Replacing shocks or bushings may be required after **5,000 10,000 miles**.

10. **Noise and Vibration** Some riders report that the 850cc engine can be louder and vibrate more than smaller ATVs, which may be a drawback for those seeking a quieter ride.

### **Conclusion**

The **Polaris 1543872-067 850 Switchback XCR AXYS 600/800 (2019 2021)** is an excellent choice for riders who prioritize **comfort, versatility, and reliability** over extreme off-road performance. It excels in **trail riding, daily commuting, and light utility tasks**, thanks to its adjustable suspension, smooth power delivery, and ergonomic design. However, it is **not ideal for deep mud, steep climbs, or heavy-duty work**, where a 4WD ATV would be more suitable.

If you plan to use the ATV primarily for **recreational trail riding, backcountry exploration, or as a comfortable all-day ride**, this model is a strong contender. If you need **maximum off-road capability, heavy hauling, or aggressive performance**, you may want to consider a **4WD ATV or a sportier RWD model with different suspension tuning**.

---

### **Recommendation**

- You want a **comfortable, low-maintenance ATV** for trails, backroads, or light utility.

- You prefer **adjustable suspension** (AXYS 600/800) for customizable ride quality.

- You prioritize **durability and reliability** over extreme off-road performance.

- You plan to **modularly upgrade** the ATV over time (e.g., exhaust, tires, lighting).

- You ride in **mixed terrain** (pavement, gravel, light trails) rather than extreme conditions.

- You need **deep mud or steep climb capability** Look at a **4WD ATV** (e.g., Polaris Ranger XP 800, Can-Am Outlander).

- You want **aggressive off-road performance** A **sportier RWD ATV** (e.g., Polaris Sportsman 570, Can-Am Defender) may be better.

- You frequently **haul heavy loads or pull trailers** A **utility-focused ATV** (e.g., Polaris Ranger, Kawasaki Mule) is more suitable.

- You prefer **lower maintenance and fuel costs** A **smaller displacement ATV** (e.g., 570cc or 650cc) could be more efficient.

**Final Verdict:** The **Switchback XCR 850 is a well-rounded, comfortable ATV** that delivers great value for riders who want a **versatile, low-stress machine** for trails and daily use. If your needs align with its strengths, it s a solid purchase. Otherwise, evaluate whether a **4WD or sportier ATV** better fits your requirements.
