Review SUZUKI Burgman Oem Crankshaft Balancers Crank Balancer Shafts fits AN650 650 2005–2009

The **Suzuki 12650-10820 Crankshaft Balancer Assembly (AN650/Burgman 650, Model Years 2005 2009)** is a precision-engineered component designed to maintain optimal balance and smooth operation within the high-performance 650cc air-cooled, single-cylinder engine found in the Suzuki Burgman 650 and AN650 models. This critical assembly consists of a pair of **crank balancer shafts**, also known as harmonic balancers or vibration dampeners, which are strategically positioned to counteract the inherent torsional vibrations generated by the engine s rotating crankshaft. Crafted from high-grade steel and meticulously machined to Suzuki s exacting specifications, these balancers feature a robust, counterweighted design that minimizes engine shake, enhances ride stability, and prolongs the lifespan of drivetrain components by reducing stress on the clutch, transmission, and frame. The assembly includes a **rubberized outer cover** that absorbs and dissipates vibrational energy, while the internal components such as the weighted flywheel and torsion bar work in tandem to dampen harmonic oscillations, ensuring a quieter, more refined power delivery. Whether installed during routine maintenance or as part of a performance upgrade, this crankshaft balancer assembly is a vital replacement part for owners seeking to restore factory-level smoothness or address symptoms of worn or damaged balancers, such as excessive vibration, unusual engine noise, or premature wear on the engine mounts. Its compatibility with the 2005 through 2009 Burgman 650/AN650 models makes it an essential component for both DIY mechanics and professional shops aiming to deliver a seamless, high-quality restoration or upgrade.

### Pros and Cons of Buying Suzuki 12650-10820 (05-09 Burgman 650 AN650 Crankshaft Balancers/Crank Balancer Shafts)

1. **Compatibility and Fitment** These balancer shafts are specifically designed for the Suzuki Burgman 650 (AN650) models from 2005 to 2009. They are direct replacements, ensuring a proper fit without modification, which reduces installation complexity.

2. **Improved Engine Balance** Worn or damaged balancer shafts can cause vibrations, rough idle, and uneven power delivery. Replacing them restores proper engine balance, leading to smoother operation, reduced wear on other engine components, and improved fuel efficiency.

3. **Prevents Further Damage** Ignoring worn balancer shafts can lead to more severe engine issues, such as damage to the crankshaft, bearings, or connecting rods. Replacing them proactively can save money on costly repairs down the line.

4. **Performance Benefits** A properly functioning balancer system helps maintain consistent power output and reduces strain on the engine, which can contribute to better throttle response and overall drivability.

5. **Long-Term Reliability** Since these parts are OEM (Original Equipment Manufacturer) or high-quality aftermarket replacements, they are built to last, reducing the likelihood of premature failure.

6. **Ease of Installation** As a direct replacement, these parts are designed to fit standard tools and procedures, making them accessible for DIY mechanics or professional shops.

7. **Cost-Effective Solution** Replacing balancer shafts is generally less expensive than overhauling the entire engine or replacing other damaged components caused by imbalanced operation.

1. **Cost** While not excessively expensive, the parts themselves, along with labor if professionally installed, can add up. For a Suzuki AN650, the cost may range from $100 to $300 depending on whether you purchase OEM or aftermarket parts and whether you install them yourself.

2. **Labor-Intensive Installation** Replacing balancer shafts requires removing the engine cover, disconnecting various components (such as the alternator, air intake, and wiring harness), and carefully aligning the shafts. This process can be time-consuming, especially for inexperienced mechanics.

3. **Potential for Counterfeit Parts** If purchasing aftermarket parts, there is a risk of receiving low-quality or counterfeit replicas. Always buy from reputable suppliers to ensure authenticity and quality.

4. **Additional Wear Check** While replacing the balancer shafts, it s wise to inspect other components like the crankshaft bearings, timing chain, and seals. If these are worn, they may need replacement as well, adding to the cost and complexity.

5. **Skill Dependency** If you lack mechanical experience, the installation process could be challenging. Mistakes during installation, such as improper alignment or torque specifications, could lead to further engine issues.

6. **Time Off the Bike** The process of replacing balancer shafts will require taking your Suzuki Burgman 650 off the road for several hours, depending on your experience level.

Replacing the crankshaft balancers on your Suzuki Burgman 650 (AN650, 2005-2009) is a worthwhile investment if your bike is exhibiting symptoms of worn balancer shafts, such as vibrations, rough idling, or power loss. The benefits smoother operation, improved reliability, and prevention of further damage outweigh the drawbacks, particularly if you address the issue early. However, the process does require careful attention to detail and either mechanical skill or access to a trusted mechanic.

If your bike is running smoothly and there are no signs of balancer shaft wear, there may not be an immediate need for replacement. In such cases, regular maintenance and monitoring for symptoms will help determine whether this repair is necessary.

---

1. **Diagnose First** If your bike is exhibiting symptoms like excessive vibration, rough idle, or uneven power delivery, confirm that the balancer shafts are the issue by consulting a mechanic or performing a visual inspection of the parts. Worn or damaged balancer shafts will often show visible cracks, bent shafts, or excessive play.

2. **Purchase Quality Parts** Opt for OEM Suzuki parts or high-quality aftermarket replacements from trusted brands (e.g., Akebono, Denso, or reputable online retailers). Avoid cheap, unknown brands to prevent premature failure.

3. **Plan for Installation** If you re comfortable with mechanical work, gather the necessary tools (socket set, torque wrench, bearing puller, etc.) and follow a step-by-step guide or video tutorial. If not, consider having a professional perform the repair to ensure proper installation and avoid costly mistakes.

4. **Inspect Related Components** While replacing the balancer shafts, take the opportunity to check other parts of the engine, such as the crankshaft bearings, timing chain, and seals. Replacing these if they are worn will extend the life of your engine.

5. **Budget Accordingly** Factor in both the cost of parts and labor (if applicable) when deciding whether to proceed. While this is not an extremely expensive repair, it s still a significant investment, so weigh it against the potential benefits.

**Final Verdict:** If your Suzuki Burgman 650 is showing signs of balancer shaft wear, replacing them is a smart and cost-effective solution to restore smooth operation and prevent further engine damage. Proceed with caution, prioritize quality parts, and consider professional help if needed. If your bike is running well, there s no urgent need for this repair, but keep an eye out for symptoms in the future.
