### **Pros and Cons of buying a Celox CL1302SC122ST Starter Clutch Bearing (Sprag) for Yamaha YFZ450 LE/SE/BBE (2004-2009)**
#### **Pros:**1. **Direct Fitment** The Celox CL1302SC122ST is specifically designed for the Yamaha YFZ450 starter clutch bearing (sprag) application, ensuring compatibility with the 2004-2009 models (LE, SE, BBE). This reduces the risk of sizing issues or installation problems.
2. **High-Quality Construction** Celox is a reputable brand known for manufacturing durable starter clutch bearings made from high-grade materials. The sprag design ensures smooth engagement and disengagement of the starter pinion, reducing wear on both the starter and flywheel.
3. **Extended Longevity** A properly functioning starter clutch bearing reduces excessive friction and wear on the starter motor and flywheel teeth. This can prolong the life of the starter and prevent premature failure of related components.
4. **Easy Installation** The bearing is designed for straightforward replacement, typically requiring only basic tools. Most users can install it without specialized equipment, saving time and labor costs.
5. **Cost-Effective Solution** While not the cheapest option, it is often more affordable than replacing the entire starter motor. It provides a targeted fix for a common failure point in older Yamaha YFZ450 models.
6. **Prevents Starter Damage** A failing starter clutch bearing can cause the starter pinion to grind against the flywheel, damaging both components. Replacing the bearing prevents this scenario, saving money on more extensive repairs.
7. **Widely Available** Celox parts are commonly stocked by motorcycle parts suppliers, both online and in physical stores, making it easy to source.

#### **Cons:**1. **Potential for Counterfeit Products** Like many aftermarket parts, Celox bearings may occasionally be counterfeit, especially if purchased from untrusted sellers. Always buy from reputable dealers to ensure authenticity.
2. **Limited Availability in Some Regions** Depending on location, finding this specific part may require ordering from an online retailer, which could introduce shipping delays.
3. **No Warranty on Some Retailers** Some sellers may not offer warranties or return policies, leaving the buyer without recourse if the part fails prematurely. Checking the retailer s return policy beforehand is advisable.
4. **Requires Basic Mechanical Skill** While the installation is relatively simple, it does require some familiarity with motorcycle maintenance. Those without experience may struggle with tasks like removing the starter motor or aligning the bearing properly.
5. **Cost Compared to DIY Alternatives** If the starter motor is already failing, replacing just the bearing may not be the most economical solution in the long run. In some cases, a new starter motor might be a better investment if the bearing fails repeatedly.
6. **Compatibility Confusion** Some buyers may mistake this part for a flywheel sprag or a different starter bearing, leading to incorrect installation. Always verify the part number and application before purchasing.
7. **Environmental Factors** If the motorcycle has been exposed to extreme conditions (e.g., excessive heat, moisture, or corrosion), the bearing may wear out faster than expected, requiring more frequent replacements.

### **Conclusion:**The **Celox CL1302SC122ST starter clutch bearing (sprag)** is a **reliable and cost-effective solution** for Yamaha YFZ450 owners experiencing starter issues between 2004 and 2009. Its direct fitment, durability, and ease of installation make it a strong choice for addressing common starter problems. However, buyers should ensure they purchase from a trusted source to avoid counterfeit parts and verify compatibility before installation.
