Review HONDA Oem Rear Subframe Sub Frame Mounting Bolts fits CR125R CR250R CR500R 1987–1988

The **Honda 90108-KA3-830** is a meticulously engineered set of **rear frame mounting bolts** specifically designed for the **1987 and 1988 model years** of Honda s iconic **CR125R, CR250R, and CR500R** off-road motorcycles. These high-performance components are crafted from **heat-treated, high-strength alloy steel**, ensuring exceptional durability and resistance to fatigue under the demanding conditions of trail riding, racing, and heavy-duty use. Each bolt is precision-machined to Honda s original specifications, maintaining the tight tolerances required for proper frame alignment and secure mounting of the rear subframe, swingarm, and other critical components. The **zinc-plated finish** provides corrosion resistance, making them ideal for both on-road and off-road environments where exposure to moisture, dirt, and abrasive elements is common. Whether restoring a classic CR series bike, upgrading a vintage rig, or ensuring peak performance in a competition setting, these bolts deliver the reliability and precision needed to keep your motorcycle s rear assembly firmly in place. Their **threaded design** matches Honda s original fitment, allowing for easy installation with standard tools, while their **torque specifications** align with manufacturer recommendations to prevent overtightening or loosening under vibration. Perfect for both DIY enthusiasts and professional mechanics, these bolts are a must-have for maintaining the structural integrity and handling balance of these legendary Honda off-roaders.

### Pros and Cons of buying a Honda 90108-KA3-830 (1988 88 CR125R/CR250R/CR500R Rear Frame Mounting Bolts)

1. **Authentic Fit and Function** These bolts are designed specifically for the 1987 88 Honda CR125R, CR250R, and CR500R models, ensuring a precise fit without modification. They are manufactured to match the original specifications, reducing the risk of misalignment or improper seating.

2. **Durability and Reliability** Honda parts, even aftermarket reproduction bolts, are generally built to withstand the stresses of off-road use. The material and threading are likely to be robust, provided they are new and unused.

3. **Ease of Installation** Since these bolts are direct replacements, they should install without requiring additional tools or adjustments beyond standard procedures. This makes them a straightforward upgrade or replacement option.

4. **Compatibility Across Models** The part number (90108-KA3-830) covers multiple CR-series models (125cc, 250cc, and 500cc) from the same year range, offering flexibility if you own or plan to own multiple bikes in this category.

5. **Prevents Rust and Wear** Over time, original bolts can corrode or wear out, leading to loose frame connections. Replacing them with new bolts can restore structural integrity and prevent potential safety hazards.

6. **Cost-Effective Solution** Compared to purchasing a full frame or custom bolts, these are a relatively inexpensive part. They provide a simple way to maintain or restore the bike without a major investment.

7. **Availability and Ease of Purchase** As a common Honda part, these bolts are likely available through online marketplaces (eBay, Amazon, specialty motorcycle parts stores), Honda dealerships, or used parts lots. This makes sourcing them convenient.

---

1. **Potential Counterfeit or Low-Quality Replicas** Buying from unverified sellers (especially online) carries a risk of receiving counterfeit or substandard bolts. These may not meet Honda s original tolerances, leading to premature failure or improper fit.

2. **Age of the Part Number** This part is over 30 years old, meaning the manufacturing standards or materials may differ from modern equivalents. While Honda parts are generally durable, older designs might not have the same corrosion resistance or precision as newer components.

3. **Limited Availability of Original Packaging** If purchasing used or from a third party, the bolts may lack original packaging, increasing the risk of damage during shipping or handling. Without packaging, you cannot verify the condition before purchase.

4. **Mismatch with Modified Bikes** If your bike has been heavily modified (e.g., aftermarket frames, suspension, or engine mounts), these bolts may not align perfectly with the new components. Always check compatibility with any modifications.

5. **No Warranty or Return Policy** Buying from private sellers or unbranded online shops often means no warranty or return options. If the bolts fail or don t fit, you may be out of luck.

6. **Thread Stripping Risk** If the original bolt holes are damaged (e.g., from rust, over-tightening, or corrosion), new bolts may strip the threads upon installation. This requires pre-cleaning or tapping the holes before use.

7. **No Upgrade in Performance** These are replacement parts, not upgrades. They will not improve the bike s performance, handling, or durability beyond restoring original functionality.

The **Honda 90108-KA3-830 rear frame mounting bolts** are a practical and cost-effective choice for restoring or maintaining a 1987 88 CR125R, CR250R, or CR500R. They offer authenticity, ease of installation, and compatibility across multiple models. However, the risk of counterfeit parts, potential age-related issues, and lack of warranty or return options are significant drawbacks, particularly when purchasing from unverified sources.

If you prioritize **reliability and authenticity**, buying from a **reputable Honda dealer, authorized parts distributor, or a trusted seller with positive reviews** is essential. If you re on a tight budget and willing to take a calculated risk, purchasing from a well-known online marketplace (with seller ratings) may be acceptable, provided you inspect the bolts for quality upon receipt.

For **long-term durability**, consider pairing these bolts with a **thread locker (e.g., Loctite 271)** to prevent loosening. Additionally, ensure the bolt holes are clean and undamaged before installation to avoid stripping.

---

1. **Best Option:** Purchase from an **official Honda dealer or a trusted motorcycle parts supplier** (e.g., Cycle World, Iron Horse, or a local shop specializing in classic Hondas). This guarantees authenticity and often includes a warranty.

2. **Budget-Friendly Alternative:** If buying online, choose a **verified seller with high ratings** (e.g., eBay Top-Rated Store, Amazon Marketplace with 4 stars) and inspect the bolts for quality before finalizing the purchase. Look for clear photos showing the packaging and condition.

- Clean the bolt holes thoroughly with a wire brush or wire wheel to remove rust or debris.

- Apply **thread locker** to prevent loosening.

- Tighten bolts to the **specified torque** (check your service manual for the correct value, typically around **20 25 ft-lbs** for these models).

4. **Avoid:** Buying from unknown sellers without reviews or return policies. If the bolts are used, ensure they are in pristine condition with no signs of wear or damage.

5. **Long-Term Maintenance Tip:** Regularly inspect the bolts and frame connections during rides or maintenance checks. Replace them if you notice any signs of corrosion, stretching, or looseness.

**Final Verdict:** These bolts are a **solid choice for restoration or maintenance**, but **prioritize sourcing from trusted vendors** to avoid counterfeit or low-quality parts. For maximum peace of mind, opt for the official route if budget allows.
