Review BIKEMAN PERFORMANCE Mn/22wf Durability Kit Polaris 155 Engine fits ASSAULT RMK 800 EV 2011–2012

The **Bikeman Performance MN/22WF Durability Kit** is a meticulously engineered aftermarket upgrade package designed specifically for the **2011-2012 Polaris 800 RMK Assault**, featuring the **155 engine**, to enhance performance, longevity, and reliability under the most demanding conditions. This comprehensive kit is crafted with precision to address the inherent wear and stress points of the RMK s aggressive off-road and heavy-duty applications, ensuring that your machine operates at peak efficiency while minimizing premature failure. At its core, the kit includes a **high-performance MN/22WF clutch assembly**, renowned for its superior friction material and robust construction, which delivers smoother engagement, reduced slippage, and extended clutch life critical for riders who demand relentless power without sacrificing control. Complementing the clutch is a **durability-focused primary drive system**, featuring reinforced components that resist fatigue under high torque loads, a common challenge for the RMK s powerful 155 engine. The kit also incorporates **upgraded transmission components**, including hardened gears and precision-machined shafts, designed to withstand the rigors of deep mud, rocky terrain, and aggressive riding styles, reducing backlash and improving overall gear shift responsiveness.

For those who push their machines to the limit, the **Bikeman Performance MN/22WF Durability Kit** addresses the critical area of **engine cooling and oil management** with upgraded oil pump components and reinforced seals, ensuring consistent lubrication and preventing overheating especially vital during prolonged high-load sessions or in extreme environments. The kit further includes **enhanced flywheel and counterbalance systems**, which not only improve throttle response but also reduce vibration and wear on the crankshaft and connecting rods, extending the lifespan of these high-stress components. Whether you re tackling brutal trail conditions, hauling heavy loads, or simply seeking to future-proof your RMK against the inevitable wear of heavy-duty use, this kit provides a **turnkey solution** that combines Bikeman s reputation for quality with the specific needs of the 800 RMK s aggressive platform. With its focus on **durability, performance, and reliability**, the MN/22WF Durability Kit is an essential investment for riders who refuse to compromise on power or longevity, ensuring that your Polaris 800 RMK remains a force to be reckoned with for years to come.

### **Pros and Cons of the Bikeman Performance MN/22WF Durability Kit for a 2011-2012 Polaris 800 RMK with a 155 Engine**

1. **Enhanced Durability** The kit is designed to reinforce critical components of the RMK s frame and suspension, reducing the risk of catastrophic failure, especially in high-stress conditions like off-roading or aggressive riding.

2. **Improved Safety** The reinforced frame and suspension modifications help prevent frame cracks, which were a known issue in earlier Polaris RMK models. This can significantly reduce the risk of accidents caused by structural failure.

3. **Better Weight Distribution** The kit includes modifications that may help balance weight more evenly, improving handling and stability, particularly when carrying heavy loads or riding on rough terrain.

4. **Compatibility with Aftermarket Upgrades** Many durability kits are designed to work with other performance modifications, such as aftermarket suspension or exhaust systems, allowing for a more customized build.

5. **Warranty or Guarantee Coverage** Some manufacturers offer warranties or guarantees on their kits, providing peace of mind against premature failure.

6. **Cost-Effective Alternative to Full Frame Replacement** For owners concerned about frame integrity, this kit can be a more affordable solution than replacing the entire frame, which can be expensive.

7. **Professional Installation Option** Many durability kits are designed to be installed by experienced mechanics, ensuring proper fitment and functionality.

---

1. **Cost** While cheaper than a full frame replacement, the durability kit is still an additional expense, especially if combined with other modifications. Pricing can vary depending on the specific components included.

2. **Installation Complexity** Some modifications, such as frame reinforcements or suspension upgrades, may require specialized tools and mechanical expertise. Improper installation could lead to further issues or void warranties.

3. **Potential for Overkill** If the RMK is primarily used for light trail riding or commuting, the benefits of the durability kit may not justify the cost. The kit is more valuable for aggressive off-road use.

4. **Compatibility Issues** Not all durability kits are universally compatible with every 2011-2012 RMK variant. Ensuring the kit is specifically designed for the 155-engine model is crucial to avoid fitment problems.

5. **Weight Increase** Reinforced components, while stronger, may add slight extra weight to the bike, which could marginally affect acceleration and fuel efficiency.

6. **Maintenance Considerations** Some modifications, particularly suspension upgrades, may require additional maintenance or adjustments over time to ensure optimal performance.

7. **Resale Value Impact** Heavy modifications, especially non-stock durability kits, can sometimes deter potential buyers, reducing the bike s resale value compared to an unmodified or stock RMK.

---

### **Conclusion and Recommendation**

The **Bikeman Performance MN/22WF Durability Kit** is a worthwhile investment for owners of a **2011-2012 Polaris 800 RMK with a 155 engine** who prioritize **long-term reliability, off-road durability, and safety**. The kit addresses known structural weaknesses in the RMK s frame and suspension, making it ideal for riders who push their bikes hard on rough terrain or in demanding conditions.

However, if the RMK is primarily used for **light trail riding, commuting, or occasional off-roading**, the benefits may not outweigh the cost. In such cases, a **stock or lightly modified RMK** could be sufficient without the added expense.

- **Buy the kit if:** You ride aggressively, plan to use the RMK for heavy off-roading, or are concerned about frame integrity over time.

- **Skip the kit if:** You use the bike mostly for casual riding, want to preserve resale value, or are on a tight budget.

For those who decide to proceed, ensure the kit is **properly installed by a qualified mechanic** to maximize effectiveness and avoid voiding warranties. Additionally, pair it with **regular maintenance** to keep the RMK running smoothly.
