Review YAMAHA Rear Wheel Spokes And Spoke Nuts Partial Set fits TTR90 2000–2020

The **Yamaha 21W-25304-00-00 2000 2007 TTR90 Rear Wheel Spoke Nuts (20-Spoke, Partial Set)** is a precision-engineered aftermarket component designed specifically for Yamaha s iconic TTR90 adventure motorcycle, produced between the years 2000 and 2007. This partial set of **20 high-quality spoke nuts** is meticulously crafted to ensure a secure and reliable fitment, maintaining optimal wheel alignment and balance while withstanding the demands of off-road and on-road riding. Crafted from durable **chrome-molybdenum steel**, these nuts are built to resist corrosion, wear, and loosening under vibration, making them an ideal replacement for worn or missing original equipment. The design features a **standard 14mm thread size**, compatible with the TTR90 s 20-spoke wheel system, ensuring a snug and tensioned fit when paired with the corresponding spokes. Whether you re restoring a vintage TTR90, upgrading an existing wheel, or addressing routine maintenance, these spoke nuts provide the necessary grip and stability to keep your wheel true and your ride smooth. Their robust construction and compatibility with Yamaha s original wheel specifications make them a trusted choice for enthusiasts seeking both performance and longevity in their motorcycle s drivetrain.

### **Pros and Cons of buying a Yamaha 21W-25304-00-00 (2000-2007 TTR90 Rear Wheel Spokes 20-Spoke Nut Partial Set)**

1. **Direct Fitment** This part is specifically designed for the **Yamaha TTR90 (2000-2007 models)**, ensuring compatibility without modification. The **20-spoke rear wheel** is a standard component for this bike, reducing the risk of mismatches.

2. **High-Quality Construction** Yamaha parts are generally built to meet or exceed OEM standards, meaning they should provide reliable performance and durability, especially if the wheel is in good condition otherwise.

3. **Partial Set Convenience** Since it s a **partial set of 20-spoke nuts**, it s likely intended for replacement rather than a full wheel rebuild. This makes it a cost-effective solution if only the nuts are worn or missing.

4. **Easy Installation** Spoke nuts are straightforward to replace, requiring only basic tools (Allen wrenches, torque wrench, and possibly a spoke wrench). No complex disassembly is needed unless the wheel is heavily damaged.

5. **Prevents Wheel Damage** Loose or missing spoke nuts can lead to wheel wobble, imbalance, or even spoke breakage. Replacing them proactively can extend the life of the wheel and improve ride quality.

6. **Cost-Effective Alternative** Purchasing OEM nuts is often cheaper than buying a full wheel or aftermarket wheels, making it a practical choice for maintenance rather than a full upgrade.

7. **Authentic Look and Feel** Using OEM parts ensures the wheel retains its original appearance and weight distribution, which may be preferable for riders who prioritize stock aesthetics.

1. **Limited Availability** Yamaha parts, especially older ones, can be harder to find compared to more common aftermarket components. If the part is discontinued, sourcing may require checking used markets or specialty dealers.

2. **Potential for Counterfeit Parts** Since this is an older model, there s a risk of purchasing **fake or low-quality replicas** if buying from untrusted sellers. Always verify the seller s reputation and part authenticity.

3. **Wheel Condition Matters** If the **rim, hub, or spokes are damaged**, replacing just the nuts won t fix underlying issues. A full wheel inspection may be necessary before installation.

4. **Torque Specifications Critical** Over-tightening or under-tightening spoke nuts can lead to **spoke stretch, rim deformation, or hub damage**. Yamaha s recommended torque (typically **10-12 Nm**) must be followed precisely.

5. **No Warranty on Used/Aftermarket Parts** If purchasing from a third party (e.g., eBay, Facebook Marketplace), there s no guarantee of warranty coverage. Yamaha s official dealerships may offer limited warranties on OEM parts.

6. **Partial Set Limitations** Since it s a **partial set**, you may need to source additional nuts if more than a few are missing. This could lead to extra costs if the set doesn t cover all required nuts.

7. **Aftermarket May Offer Better Options** Some aftermarket spoke nuts (e.g., **Quicker, DT Swiss, or Mavic**) are designed with **better corrosion resistance, lighter weight, or easier installation**. If upgrading, these may be worth considering despite a higher cost.

### **Conclusion**

- You need **only the nuts replaced** due to wear or loss.

- You want **OEM compatibility** without modifying the wheel.

- The rest of the wheel (rim, hub, spokes) is in **good condition**.

- You re comfortable with **basic maintenance tasks**.

- The wheel has **significant damage** (bent rim, loose hub, broken spokes), a full inspection or replacement may be needed.

- You re open to **aftermarket upgrades** for better durability or performance, consider higher-quality nuts.

- You can t verify the **authenticity of the part**, especially if buying used.

### **Recommendation**

1. **Verify Wheel Condition First** Before purchasing, check the **rim for cracks, spokes for stretch, and the hub for play**. If any issues exist, address them before replacing just the nuts.

2. **Buy from a Trusted Source** Prefer **Yamaha-authorized dealers, reputable online retailers (like Cycle Parts Direct, Amazon, or eBay with positive feedback), or used parts from verified sellers**.

3. **Check for Alternatives** If the part is hard to find, consider **aftermarket 20-spoke nuts** (e.g., **Quicker 12x1.8mm or DT Swiss**) if they fit the wheel pattern. These often have better corrosion resistance.

4. **Follow Torque Specs Precisely** Use a **torque wrench** to tighten nuts to **10-12 Nm** (Yamaha s recommendation). Over-tightening can damage the wheel.

5. **Consider a Full Wheel Inspection** If the wheel has been in service for a long time, a **professional bike shop** may recommend a full rebuild for optimal safety.

For a **quick, budget-friendly fix** to replace worn-out nuts on an otherwise sound wheel, this Yamaha part is a **solid choice**. However, if you re unsure about the wheel s condition or want long-term reliability, prioritize a **full inspection** and consider **aftermarket upgrades** if available.
