Review HONDA Adjuster Rear Showa Shock Suspension Oem fits CRF450R CRF 2022–2024

The **Honda 52400-MKE-AA1 2022 CRF450R Rear Shock Adjustable Suspension** is a precision-engineered component designed to elevate the performance, comfort, and handling of Honda s iconic CRF450R dirt bike across its 2022 through 2024 model years. Crafted by Showa, one of the most respected names in motorcycle suspension technology, this rear shock absorber is a critical element in delivering a balanced, responsive, and durable riding experience. The shock features a **fully adjustable preload system**, allowing riders to fine-tune the spring tension to match their weight, riding style, and terrain preferences whether tackling aggressive off-road trails, carving through technical jumps, or cruising on smoother terrain. This adjustability ensures optimal wheel travel, reducing bottoming out and improving traction, while also minimizing unnecessary stress on the bike s frame and drivetrain.

Under the hood of this suspension system lies **Showa s advanced damping technology**, which combines high-quality materials and meticulous engineering to deliver smooth, consistent performance. The shock incorporates a **compression damping system** that adjusts to rider input with minimal lag, providing a progressive feel that enhances control during aggressive maneuvers while maintaining stability at high speeds. Meanwhile, the **rebound damping** is finely tuned to prevent excessive wheel hop and ensure quick, responsive wheel movement, which is essential for maintaining traction during rapid acceleration and braking. The shock s **gas-charged nitrogen chamber** further enhances stability by minimizing air compression, reducing heat buildup, and maintaining consistent damping performance even under demanding conditions.

Built to withstand the rigors of competitive and recreational riding, the **2022-2024 CRF450R rear shock** is constructed from durable, high-grade steel and reinforced components, ensuring longevity and reliability. The shock s **sealed design** protects internal components from dirt, debris, and moisture, while the **robust mounting hardware** guarantees a secure and vibration-free connection to the bike s swingarm. Honda s integration of this suspension system into the CRF450R s chassis underscores its role in delivering the bike s signature blend of agility, power, and rider confidence. Whether you re a professional motocross racer fine-tuning your setup for a race weekend or an enthusiast seeking to optimize your bike for weekend trail rides, this rear shock offers the precision and adaptability needed to maximize performance. With its combination of adjustability, durability, and Showa s legendary craftsmanship, it stands as a cornerstone of the CRF450R s reputation as a versatile and high-performance off-road machine.

### **Pros and Cons of Buying a 2022 Honda CRF450R with the 52400-MKE-AA1 (2022-2024) Showa Rear Shock Adjustable Suspension**

1. **Performance-Oriented Design**

The CRF450R is Honda s flagship off-road motorcycle, engineered for aggressive trail riding, motocross, and enduro. Its lightweight aluminum frame, high-revving 450cc parallel-twin engine, and precise handling make it a favorite among competitive riders.

2. **Adjustable Rear Shock (Showa BFRC)**

The **52400-MKE-AA1** rear shock is a **BFRC (Burst Valve-Free Ride Control)** unit, allowing riders to fine-tune compression and rebound damping via a **quick-adjust dial** on the right side of the swingarm. This is ideal for riders who need to adapt to different terrains (rocky trails, sand, jumps) without removing the wheel. The BFRC system also provides a **progressive feel**, improving control at high speeds.

3. **Durability and Reliability**

Honda s reputation for long-lasting components is well-earned. The CRF450R s engine, suspension, and drivetrain are built to withstand heavy use, making it a practical choice for serious riders who demand durability.

4. **Aftermarket Support**

The CRF450R has a **thriving aftermarket**, with availability of upgraded parts (exhausts, forks, clutches, etc.) for those looking to push performance further. The adjustable rear shock also integrates well with aftermarket upgrades.

5. **Comfortable for Long Rides**

While primarily a trail/motocross bike, the CRF450R s ergonomics and suspension tuning make it more comfortable for **longer rides** compared to pure motocross bikes. The adjustable rear shock helps in smoothing out rough terrain without sacrificing performance.

6. **Resale Value**

Honda CRF models, especially the 450R, hold their value well due to their reputation for reliability and performance. This makes it a smarter long-term investment compared to some competitors.

7. **Fuel Injection & Electronic Management**

The bike features **PGM-FI (Programmed Fuel Injection)** and an **ECU with traction control (TC)** and launch control, which help optimize power delivery and stability, especially in demanding conditions.

---

1. **Higher Price Point**

The CRF450R is **more expensive** than entry-level trail bikes or motocross machines. The **adjustable rear shock** (BFRC) adds to the cost compared to standard shocks, making it a premium choice.

2. **Weight (Compared to Some Rivals)**

At around **220-230 lbs (wet)**, the CRF450R is **heavier** than some lightweight trail bikes (e.g., KTM 350/450 SX-F) or naked bikes. This can make it slightly less nimble in tight technical sections, though it remains very capable.

3. **Maintenance Costs**

While reliable, Honda s **OEM parts and labor costs** can be higher than some competitors (e.g., KTM, Husqvarna). The adjustable shock, while convenient, may require more frequent tuning than a basic shock.

4. **Not a Pure Motocross Bike**

The CRF450R is **dual-sport**, meaning it s optimized for trails and light motocross rather than **full-on dirt track racing**. If you re racing in a motocross league, a bike like the **Honda CRF450RX** (motocross-specific) or **KTM 450 SX-F** might be better suited.

5. **Suspension Tuning Limitations**

While the **rear shock is adjustable**, the **front forks (USF-200) are not**. This means you re limited to **stock fork settings** unless you upgrade. Some riders prefer full fork adjustability for extreme conditions.

6. **Fuel Economy (Not Ideal for Long Commutes)**

The CRF450R is **not fuel-efficient** expect around **40-50 mpg** in trail riding. If you need a bike for daily commuting, a sport-touring or adventure bike would be more practical.

7. **Learning Curve for Beginners**

The bike s **aggressive geometry and high power delivery** can be intimidating for **new riders**. It requires confidence to handle properly, especially at high speeds or on technical terrain.

---

### **Conclusion**

The **2022-2024 Honda CRF450R with the 52400-MKE-AA1 adjustable rear shock** is an **excellent choice** for riders who prioritize **performance, adjustability, and reliability** in a dual-sport/motocross bike. The **BFRC rear shock** is a **major upgrade** over standard shocks, allowing for on-the-fly tuning to different conditions, which is invaluable for competitive trail riding.

However, if you're looking for **a lighter, more motocross-focused bike**, a **KTM 450 SX-F or Husqvarna TE 450** might be better. If you need **full suspension adjustability**, consider an aftermarket fork upgrade. For **daily commuting or fuel efficiency**, this bike is overkill.

### **Recommendation**

You ride **aggressive trails, motocross, or enduro** and want **adjustable suspension** without removing the wheel.

You value **Honda s reliability and resale value**.

You re comfortable with a **slightly heavier bike** and don t mind its **higher cost**.

You plan to **upgrade other components** (exhaust, clutch, etc.) for better performance.

You need **full fork adjustability** (consider aftermarket forks).

You re a **beginner rider** who wants something more forgiving.

You primarily ride **pavement or commute** (a sport-tourer or adventure bike is better).

You re on a **tight budget** (the CRF450R is expensive, and maintenance can add up).

The **CRF450R with the adjustable rear shock is one of the best dual-sport/motocross bikes** for riders who want **precision, adjustability, and Honda s engineering**. If you can afford it and need a bike that performs well in **competitive trail riding**, this is a **strong recommendation**. For everything else, consider alternatives based on your specific needs.
