Review YAMAHA Oem Rear Wheel Spacers Collars Good fits YZ250 YZ 250 1989–1990

The **Yamaha 90387-2000B-00 (89-90 YZ 250 YZ250 Rear Wheel Spacers/Collars)** is a precision-engineered aftermarket component designed exclusively for Yamaha s 1989 and 1990 YZ250 motocross and enduro models, offering riders the ability to fine-tune their rear wheel alignment with ease. These spacers and collars are crafted from high-quality, durable materials to ensure long-lasting performance under the demanding conditions of off-road riding, where heat, vibration, and impact are constant challenges. The set includes two robust spacers and two matching collars, all meticulously machined to fit snugly between the rear axle and the swingarm, allowing for incremental adjustments to the wheelbase. This customization is invaluable for optimizing handling, suspension geometry, and tire clearance, enabling riders to dial in their bike s behavior for improved traction, stability, and responsiveness whether tackling tight technical trails or aggressive jumps. Whether you re a competitive racer looking to shave milliseconds off lap times or an enthusiast seeking a more tailored riding experience, these spacers provide a straightforward yet effective solution to refine your YZ250 s performance without compromising structural integrity. Built to Yamaha s exacting standards, they integrate seamlessly with the original hardware, ensuring a secure and reliable fit while offering the flexibility to experiment with different spacings to achieve the perfect balance between aggression and control. Ideal for both stock and modified setups, these components are a must-have for any rider serious about maximizing their bike s potential on the track or in the backcountry.

### **Pros and Cons of Buying Yamaha 90387-2000B-00 (YZ250 Rear Wheel Spacers/Collars)**

1. **Compatibility** These spacers and collars are designed specifically for the **Yamaha YZ250 (1989-1990 models)**, ensuring a proper fit without modification. This reduces the risk of misalignment or damage to the wheel or suspension.

2. **Improved Wheel Alignment** If the stock wheel spacing is causing issues (such as rubbing on the swingarm or frame), these spacers can adjust the wheel position, reducing friction and potential damage.

3. **Durability** Yamaha parts are generally built to last, especially if they are OEM or high-quality aftermarket replacements. The materials used in these spacers and collars are likely to withstand the stresses of off-road riding.

4. **Easy Installation** Since these are direct replacements for the stock components, installation should be straightforward for someone with basic mechanical skills. No major modifications to the bike are required.

5. **Cost-Effective Fix** If the issue is purely wheel spacing-related (e.g., rubbing, misalignment), these spacers may be a cheaper alternative to replacing the entire wheel or swingarm.

6. **Potential Performance Benefit** Proper wheel spacing can improve handling by reducing lateral play or binding, which may lead to better stability, especially at high speeds or during aggressive riding.

7. **Availability of Parts** As a common Yamaha part, these spacers/collars are likely available from multiple sources (Yamaha dealers, online marketplaces, or specialty bike shops), making them easier to source than rare or discontinued components.

---

1. **Limited Use Case** These spacers are **only for the 1989-1990 YZ250 models**. If you have a different year or model, they will not fit, and purchasing them would be a waste of money.

2. **Potential Overcorrection** If the wheel was not the original issue (e.g., bent swingarm, worn bearings, or frame misalignment), adding spacers may not solve the problem and could even worsen it by forcing the wheel into an improper position.

3. **No Adjustability** Unlike some aftermarket solutions, these are fixed-size spacers. If your wheel spacing issue requires a different thickness, you may need multiple sets or a custom solution.

4. **Possible Suspension Impact** Adjusting wheel spacing can affect suspension geometry, particularly the rear travel and geometry angles. If not done carefully, it may lead to poor handling, uneven tire wear, or premature suspension wear.

5. **Quality Variability** While Yamaha parts are generally reliable, aftermarket replicas (if purchased from non-OEM sources) may vary in quality. Cheaper alternatives might wear out faster or fail prematurely.

6. **Labor Dependency** If you lack mechanical experience, installing these spacers may require professional help, adding to the overall cost.

7. **Not a Permanent Solution** If the underlying issue (e.g., frame damage, worn components) is not addressed, spacers alone will not provide a long-term fix.

The **Yamaha 90387-2000B-00 rear wheel spacers/collars** are a **practical and cost-effective solution** for **1989-1990 YZ250 owners** experiencing wheel rubbing, misalignment, or spacing issues. They offer a **direct, compatible fix** with minimal installation complexity, assuming the problem is purely related to wheel positioning.

However, they are **not a universal fix** if the issue stems from other mechanical failures (e.g., bent swingarm, worn bearings, or frame damage), these spacers may not resolve the problem and could even exacerbate it. Additionally, improper installation or over-adjustment could negatively impact handling and suspension performance.

- You have confirmed that the **wheel spacing is the root cause** of your issue (e.g., rubbing against the swingarm or frame).

- You are certain the **1989-1990 YZ250 model** matches the part number.

- You are comfortable with basic bike maintenance or have access to a mechanic for installation.

- Your bike is **not a 1989-1990 YZ250**, as these parts are **model-specific**.

- The problem persists after installation, suggesting a **deeper mechanical issue** (e.g., frame damage, suspension misalignment).

- You are unsure about the **correct spacing measurement** consult a Yamaha manual or expert before purchasing.

- If the wheel is **worn or damaged**, replacing it may be more cost-effective than relying on spacers.

- For **custom spacing adjustments**, consider **aftermarket solutions** (e.g., adjustable spacers or wheel adapters) if the stock parts do not fit your needs.

- Always **check for frame or swingarm damage** before assuming spacers will fix the issue.

**Final Verdict:** These spacers are a **solid choice for their intended purpose**, but they should be used as a **diagnostic tool** if the problem remains after installation, further inspection is necessary. Always prioritize **proper diagnosis** over quick fixes to avoid recurring issues.
