### **Pros and Cons of buying a Yamaha 22F-15660-00-00 (TTR90/TTR90E Kickstart Shaft Axle, Starter Spindle, Gear, Ratchet, Spring)**
#### **Pros:**1. **Compatibility** This part is specifically designed for the **Yamaha TTR90 and TTR90E**, ensuring a perfect fit without modifications. It s a direct replacement for the kickstart mechanism, reducing the risk of installation issues.
2. **Durability** Yamaha uses high-quality materials in their OEM parts, which are built to withstand regular use, especially in off-road and adventure motorcycles. The ratchet, spring, and shaft are reinforced for longevity.
3. **Reliability** Since this is an original equipment (OEM) part, it maintains the same performance standards as the factory component. It should function smoothly without premature wear, provided it s installed correctly.
4. **Ease of Installation** The part comes as a complete assembly (shaft, axle, starter spindle, gear, ratchet, and spring), simplifying the replacement process. Many users report that it fits in place of the original kickstart mechanism with minimal effort, especially if the bike s kickstart mechanism is worn out.
5. **Cost-Effective Alternative to Full Rebuild** Replacing just the kickstart assembly is far cheaper than buying a used or rebuilt bike. It extends the life of an otherwise functional motorcycle without a full overhaul.
6. **Prevents Further Damage** A failing kickstart mechanism can lead to more serious issues, such as damage to the clutch or transmission if the ratchet or spring fails. Replacing it early can prevent costly repairs down the line.
7. **Aftermarket Support** Yamaha parts are widely available through dealers, online retailers, and motorcycle repair shops. If issues arise, finding replacements or assistance is easier than with aftermarket parts that may not be as standardized.

#### **Cons:**1. **Price** While cheaper than a full bike rebuild, this part is not extremely budget-friendly. For a used TTR90/TTR90E, replacing just the kickstart assembly may still feel like a significant expense, especially if the bike has other wear-and-tear issues.
2. **Installation Skill Required** Though the part is designed for straightforward replacement, it may require some mechanical skill, especially if the bike s kickstart mechanism is corroded or difficult to access. A novice may struggle without proper tools or guidance.
3. **Potential for Counterfeit Parts** Purchasing from untrusted sellers (especially online marketplaces) risks receiving counterfeit or low-quality replicas. Always buy from authorized Yamaha dealers or reputable retailers to ensure authenticity.
4. **Limited Lifespan if Misused** If the bike is frequently ridden in extreme conditions (e.g., heavy off-roading, mud, or water), the kickstart mechanism may still wear out faster than expected. Proper maintenance (e.g., lubrication) is necessary to maximize its lifespan.
5. **No Warranty on Aftermarket Purchases** If buying from a third-party seller rather than a Yamaha dealer, warranty coverage may be nonexistent or limited. OEM parts from dealers typically come with some form of warranty.
6. **May Not Solve Underlying Issues** If the kickstart mechanism fails due to a larger problem (e.g., clutch misalignment, transmission damage), replacing just this part won t fix the root cause. A full inspection may be needed.
7. **Availability Issues** Depending on location, this part might not be readily available at all Yamaha dealers, requiring online orders or shipping delays.

### **Conclusion:**The **Yamaha 22F-15660-00-00 kickstart assembly** is a **highly recommended replacement part** for TTR90/TTR90E owners experiencing kickstart failure. Its **OEM quality, compatibility, and durability** make it a reliable choice for restoring or maintaining the bike s functionality. However, the **cost, installation difficulty, and potential for counterfeit parts** are factors to consider before purchasing.
If the bike is otherwise in good condition and the kickstart mechanism is the primary issue, this part is a **practical and cost-effective solution**. For those without mechanical experience, consulting a motorcycle mechanic for installation is advisable.
### **Recommendation:**- **Buy from an authorized Yamaha dealer** to ensure authenticity and warranty coverage.

- **Consider the bike s overall condition** if other components (clutch, transmission) are worn, address them simultaneously to prevent future issues.
- **Follow installation instructions carefully** to avoid damaging adjacent parts.
- **Lubricate the kickstart mechanism regularly** to extend its lifespan.
For most TTR90/TTR90E owners dealing with a faulty kickstart, this part is **worth the investment** and will save money compared to buying a new or rebuilt bike.
