The **Honda 17372-KCE-670 XR250R Crankcase Crank Engine Vent Breather Hose/Tube (1987 Model)** is a precision-engineered component designed specifically for the iconic Honda XR250R dual-sport motorcycle, ensuring optimal engine performance and longevity. This high-quality rubber and reinforced hose assembly serves as a critical link in the motorcycle s crankcase ventilation system, allowing proper airflow to escape excess pressure generated during engine operation.

The reinforced construction of the hose also enhances its resistance to kinking or cracking over time, making it a reliable long-term solution for maintaining your XR250R s engine health. Whether you re tackling rugged trails or cruising on paved roads, this genuine Honda part guarantees seamless operation, helping to preserve the engine s efficiency and extend its service life. For riders who demand both performance and durability, this breather hose is an essential replacement part that upholds the legendary reliability of the Honda XR250R.

**Pros and Cons of buying a Honda 17372-KCE-670 XR250R Crankcase Crank Engine Vent Breather Hose Tube (1987 Model)**

### **Pros:**

1. **Direct Fitment** This part is specifically designed for the 1987 Honda XR250R, ensuring compatibility without modifications. It will slot in seamlessly, reducing the risk of installation errors.

2. **Authentic Replacement** As an OEM (Original Equipment Manufacturer) or high-quality aftermarket part, it maintains the original performance and functionality of the breather system, which is critical for proper crankcase ventilation and engine longevity.

3. **Prevents Oil Contamination** A faulty or missing breather hose can allow crankcase gases (including oil vapors) to enter the air filter, clogging it and reducing engine efficiency. This part helps maintain clean airflow and prevents oil buildup in the filter.

4. **Easy Installation** The hose is typically a straightforward replacement, requiring minimal tools and time. Most riders can install it themselves with basic mechanical skills.

5. **Cost-Effective** Compared to the potential damage caused by a failing breather system (such as oil leaks, filter clogs, or engine wear), replacing this hose is a small investment that prevents costly repairs down the line.

6. **Availability** While parts for older models like the 1987 XR250R may be harder to find, this specific item is likely available through Honda dealerships, specialty motorcycle parts suppliers, or online marketplaces like eBay, RockAuto, or Partzilla.

7. **Durability** If sourced from a reputable brand (even if aftermarket), the hose should be made from durable materials like rubber or silicone, resistant to heat, oil, and environmental exposure.

### **Cons:**

1. **Age of the Part** Since this is a part for a nearly 40-year-old motorcycle, finding a *brand-new* OEM hose may be difficult. You might end up with a used or refurbished part, which could have wear or unknown service history.

2. **Potential Counterfeit or Low-Quality Replacements** Some aftermarket or third-party sellers may offer knockoff or subpar hoses that crack, harden, or fail prematurely. Always verify the seller s reputation and material quality before purchasing.

3. **Limited Lifespan** Even with proper care, rubber or silicone hoses can degrade over time due to exposure to heat, oil, and UV light. The hose may need replacement every few years or sooner if the motorcycle is ridden frequently.

4. **Compatibility Risks** While the part is designed for the 1987 XR250R, slight variations in later or earlier model years (e.g., 1986 1988) could cause fitment issues. Double-check the part number and year-specific details before buying.

5. **Cost vs. New Motorcycle** For a very old bike, the cost of this part may seem negligible, but if the motorcycle is already in poor condition, investing in a breather hose alone may not justify restoring the entire machine.

6. **DIY Installation Challenges** If the rider lacks mechanical experience, improper installation (e.g., incorrect routing, loose clamps, or misalignment) could lead to leaks or reduced effectiveness. Consulting a mechanic or a detailed guide may be necessary.

7. **Environmental Factors** If the motorcycle is stored in extreme conditions (e.g., freezing temperatures, excessive humidity, or salt exposure), the hose may degrade faster than expected.

### **Conclusion:**

The **Honda 17372-KCE-670 breather hose tube** is a **practical and necessary replacement part** for maintaining the health of a 1987 XR250R s engine. Its primary benefits direct fitment, prevention of oil contamination, and ease of installation outweigh the minor drawbacks, especially for riders who prioritize long-term engine reliability. However, the challenges of sourcing an authentic part, ensuring quality, and verifying compatibility must be addressed before purchase.

For most riders, **this is a worthwhile investment** if the motorcycle is otherwise in good condition and used regularly. Skipping this replacement could lead to more significant (and expensive) issues like filter clogs, reduced power, or even engine damage over time.

---

### **Recommendation:**

1. **Source from a Trusted Supplier** Purchase from a reputable dealer (e.g., Honda dealership, RockAuto, or a well-reviewed online seller) to avoid counterfeit or low-quality parts. If buying used, inspect the hose for cracks, brittleness, or signs of wear.

2. **Verify Part Compatibility** Confirm that the part number (17372-KCE-670) matches your exact model year (1987) and engine variant. Some aftermarket hoses may require slight modifications (e.g., cutting to length).

3. **Inspect the Existing Hose** Before buying, check the current hose for damage. If it s already failing, replace it immediately. If it s in good condition, the new hose may serve as a backup or for future maintenance.

4. **Consider a High-Quality Aftermarket Alternative** If the OEM part is unavailable, brands like **Gasket Maker, Motorex, or Denso** offer reliable aftermarket breather hoses that often come with better warranties or reviews.

5. **Install Properly** Follow the manufacturer s instructions or consult a mechanic if unsure. Ensure the hose is securely clamped and routed correctly to prevent leaks or kinks.

6. **Maintain the System** Regularly inspect the breather system (hose, filter, and crankcase vents) during oil changes or tune-ups. Replace the hose every 3 5 years or sooner if it shows signs of aging.

7. **Evaluate the Bike s Overall Condition** If the XR250R is a project bike with other major issues (e.g., worn bearings, transmission problems, or frame rust), weigh the cost of this part against the bike s potential value. For a daily rider or a well-maintained classic, the breather hose is a smart upgrade.

**Final Verdict:** **Buy the part if you need it and can source it reliably.** It s a small but critical component that protects the engine s longevity. For most riders, the peace of mind and performance benefits justify the cost.
