Review ATHENA Big Bore Cylinder Only 435cc 4.00mm Oversize To 94.00mm fits 2006–2009

The **Athena 1301-A179180 ATV Big Cylinder Kit** is a high-performance upgrade designed specifically for Honda ATV models from 2006 to 2009, including the popular TRX250X, TRX350X, and TRX450X series. This meticulously engineered kit features a **435cc big bore cylinder**, engineered to enhance displacement and torque output while maintaining reliability and durability.

Crafted from premium materials, the cylinder is precision-machined to exacting standards, ensuring a tight seal and optimal compression for maximum efficiency. This kit is compatible with stock Honda engines, requiring minimal modifications to the existing components, making it a straightforward yet impactful upgrade for riders looking to push their ATV s performance boundaries. Whether tackling rugged trails, hauling heavy loads, or simply craving more power, the Athena Big Cylinder Kit delivers a measurable performance enhancement that stands out in the aftermarket tuning community. Built to withstand the demands of aggressive riding, this upgrade is a testament to Athena s reputation for quality and innovation in ATV modifications.

### **Pros and Cons of buying a Athena 1301-A179180 ATV Big Cylinder Kit (435cc, 4.00mm, 94.00mm) for 2006 2009 Models**

1. **Increased Power and Performance** The larger cylinder (435cc) and upgraded components (4.00mm piston, 94.00mm bore) significantly boost horsepower and torque, making the ATV more responsive and capable of handling heavier loads or rough terrain.

2. **Improved Durability** A well-built aftermarket kit like Athena s can enhance engine longevity by reducing wear on internal components, especially if the original engine was worn or underpowered.

3. **Better Fuel Efficiency (Potentially)** A more efficient combustion chamber and optimized piston design may improve fuel economy compared to a stock, worn engine.

4. **Customization and Upgrade Potential** This kit allows for further modifications, such as tuning or upgrading other components (e.g., exhaust, carburetor, or transmission), to fine-tune performance.

5. **Cost-Effective Alternative to Replacement** If the original engine is failing, a rebuild with this kit may be cheaper than buying a used or new ATV.

6. **Compatibility with Stock Frame** Since it s designed for 2006 2009 models, it should fit without major modifications to the frame or drivetrain.

7. **Athena s Reputation** Athena is a well-known brand in ATV and motorcycle performance parts, suggesting reliability and quality in their kits.

1. **Installation Complexity** Rebuilding an engine requires mechanical skill, proper tools, and patience. If not done correctly, it could lead to further damage or poor performance.

2. **Potential for Overbuilding** If the rest of the ATV (transmission, drivetrain, suspension) is not upgraded, the increased power may strain these components, leading to premature wear or failure.

3. **Cost of Additional Modifications** While the kit itself may be affordable, you may need to invest in complementary upgrades (e.g., clutch, exhaust, or transmission) to safely handle the extra power.

4. **Warranty Void** Most aftermarket engine kits void the manufacturer s warranty, meaning you ll be responsible for any future issues.

5. **Learning Curve for Tuning** If you plan to adjust the carburetor or ECU (if applicable), you may need to experiment with settings, which could temporarily affect performance until optimized.

6. **Risk of Poor Quality Parts** While Athena is reputable, counterfeit or low-quality aftermarket parts can sometimes slip into the market. Buying from an authorized dealer reduces this risk.

7. **Time-Consuming Process** A full engine rebuild, including disassembly, machining, and reassembly, can take several hours (or even days) depending on experience.

The **Athena 1301-A179180 big cylinder kit** is a **strong upgrade** for a 2006 2009 ATV, offering **noticeable power gains, improved reliability, and customization options**. However, it requires **mechanical skill, additional planning (for supporting components), and patience** to install correctly.

If you re **comfortable with engine work** and willing to invest in **complementary upgrades** (e.g., clutch, exhaust, or suspension), this kit is a **great value** for boosting performance. If you re **not experienced with engine rebuilds** or want a **quick, hassle-free solution**, you may prefer a **pre-built high-performance engine** or a **used ATV with a stronger stock engine**.

- You have **mechanical experience** or are willing to learn.

- You re prepared to **upgrade supporting components** (clutch, transmission, exhaust) to handle the extra power.

- You want a **cost-effective way to revive an older ATV** rather than replacing it entirely.

- You **lack engine rebuild experience** and would rather avoid the risk of mistakes.

- You want **immediate performance** without the hassle of a DIY rebuild (e.g., buying a **used high-performance ATV** or a **pre-built engine swap**).

- You plan to **use the ATV for light duty** and don t need extreme power gains.

**Final Verdict:** For the right buyer with the right preparation, this kit is a **solid upgrade** but it s not a "plug-and-play" solution. If you re serious about maximizing your ATV s performance, it s worth the effort. Otherwise, weigh the trade-offs carefully.
