( Manufacturer Part Number: 12200-28E00 ), ( Country Of Origin: Japan )

Review SUZUKI Engine Crankshaft Crank Shaft Connecting Rod Assembly fits RM250 1993

The **Suzuki 1993 RM250 Engine Crankshaft (Part No. 12200-28E00)** is a meticulously engineered component designed to deliver the raw, high-performance power that defines Suzuki s legendary two-stroke racing motorcycles. This crankshaft is a critical element of the RM250 s drivetrain, responsible for converting the explosive energy of combustion into smooth, linear motion that propels the bike at breakneck speeds. Crafted from high-grade forged steel, the crankshaft is precision-machined to exacting tolerances, ensuring durability under the extreme stresses of aggressive racing and high-revving operation. Its robust construction features a **two-bolt main bearing design**, a hallmark of Suzuki s engineering, which distributes load evenly across the crankpins to minimize vibration and maximize efficiency. The crankshaft s **connecting rod (part of the assembly)** is similarly built to withstand the immense forces generated by the RM250 s high-revving, two-stroke engine, with reinforced walls and optimized geometry to maintain structural integrity even under the most demanding conditions. This component is a direct replacement for the original equipment, ensuring a perfect fit with the 1993 RM250 s cylinder block, flywheel housing, and other drivetrain elements. Whether restoring a classic race bike to its former glory or upgrading an existing engine for enhanced performance, this crankshaft assembly delivers the reliability and power output that enthusiasts expect from Suzuki s iconic off-road machinery. Its compatibility with aftermarket upgrades, such as high-performance pistons or camshafts, further extends its versatility, making it an essential part for both purists and performance seekers alike.

### Pros and Cons of Buying a 1993 Suzuki RM250 Engine (12200-28E00 Crankshaft/Crankshaft Connecting Rod)

1. **Common and Widely Available** The Suzuki RM250 is a classic dirt bike known for its reliability and durability. Parts, including crankshafts and connecting rods, are readily available from aftermarket suppliers, salvage yards, and online marketplaces. This makes sourcing replacements easier compared to less common engines.

2. **Proven Performance** The RM250 s engine, particularly the 249cc two-stroke design, is well-regarded for its smooth operation and power delivery. A well-maintained crankshaft and connecting rod assembly can provide reliable performance for years, especially if the bike is used for light to moderate off-road riding.

3. **Cost-Effective Replacement** Compared to OEM parts, aftermarket crankshafts and connecting rods for this engine are often significantly cheaper. For example, a used or refurbished set may cost a fraction of the price of a new OEM part, making it a budget-friendly option for repairs.

4. **Repairable and Upgradable** The RM250 s engine is relatively simple compared to modern four-strokes, meaning repairs like replacing a crankshaft or connecting rod are manageable for DIYers with basic mechanical skills. Additionally, there are performance upgrades (e.g., porting, carburetor tweaks) that can extend the engine s lifespan and improve its output.

5. **Community Support** The RM250 has a large and active enthusiast community. Forums, YouTube tutorials, and repair guides are abundant, making it easier to troubleshoot issues, find compatible parts, and get advice on installation or maintenance.

6. **Long-Term Durability** When properly maintained, the RM250 s engine can last well beyond its original lifespan. Many bikes from this era, with regular upkeep, have exceeded 10,000 15,000 miles. A fresh crankshaft and connecting rod can restore performance and prevent catastrophic failure.

7. **Versatility** The RM250 is used in motocross, enduro, and even street applications (e.g., chopper builds). This means parts like crankshafts and rods are cross-compatible with other Suzuki models (e.g., DR250, GT250) or can be adapted for custom builds.

1. **Wear and Tear** A 1993 RM250 engine, especially one with a used crankshaft or connecting rod, may have hidden damage. Signs of wear such as scoring, bending, or cracks in the crankshaft or rod journals can lead to premature failure if not addressed. Always inspect for:

- Bent or warped crankshafts.

- Worn rod bearings or bushings.

- Cracks in the rod or crankshaft material (common in aluminum rods).

- Excessive play in the connecting rod bearings.

2. **Quality Variability** Used or aftermarket parts may not meet OEM specifications. Cheap or poorly machined crankshafts or rods can lead to poor performance, increased wear on other engine components (e.g., pistons, cylinders), or even engine damage. Always verify the source and quality of the parts.

3. **Maintenance Requirements** Two-stroke engines like the RM250 require meticulous maintenance, including regular oil mixing, chain and sprocket checks, and valve adjustments. Neglecting maintenance can exacerbate issues with the crankshaft or rods, leading to costly repairs down the line.

4. **Limited Lifespan with Abuse** While the RM250 is durable, aggressive riding (e.g., heavy braking, sharp cornering, or frequent high-RPM use) can accelerate wear on the crankshaft and connecting rod. If the bike has a history of rough treatment, the parts may not last as long as expected.

5. **Compatibility Issues** Ensure the crankshaft and connecting rod are compatible with your specific RM250 model. Some aftermarket parts may not fit due to differences in crankpin diameter, rod length, or bearing sizes. Always check measurements or consult a mechanic before purchasing.

6. **Potential for Hidden Damage** A crankshaft or connecting rod that appears intact may have internal damage (e.g., fatigue cracks, case hardening issues). Without a thorough inspection (e.g., magnetic particle testing for cracks), you risk buying a part that fails shortly after installation.

7. **Environmental and Legal Factors** In some regions, two-stroke engines are restricted or banned due to emissions regulations. If you plan to use the bike on public trails or roads, check local laws to avoid fines or registration issues.

Buying a used or aftermarket **1993 Suzuki RM250 crankshaft and connecting rod** can be a cost-effective way to restore or maintain your bike, especially if you prioritize performance and reliability. The RM250 s widespread availability and community support make it easier to source parts and find solutions to common issues. However, the risks of purchasing worn or low-quality parts cannot be ignored. Hidden damage, compatibility issues, and the need for meticulous maintenance are significant drawbacks that must be carefully managed.

- **Verify the condition** of the crankshaft and rods through visual inspection, measurement, and ideally, professional testing (e.g., for cracks or wear).

- **Source parts from reputable sellers** (e.g., eBay with positive feedback, specialty motorcycle parts stores, or trusted salvage yards).

- **Budget for additional maintenance** (e.g., new bearings, seals, or a full engine rebuild if other components are worn).

- **Consider a rebuild kit** if the engine shows signs of extensive wear, as replacing just the crankshaft and rods may not be sufficient for long-term reliability.

For a **budget-conscious rider** looking to extend the life of their RM250 with minimal investment, a used or refurbished crankshaft and connecting rod from a trusted source is a viable option **provided you inspect them thoroughly and are prepared for potential follow-up repairs**. However, if the engine shows signs of advanced wear (e.g., blue smoke, excessive oil consumption, or a history of frequent breakdowns), a **full engine rebuild or replacement** may be more cost-effective in the long run.

For **serious riders or racers**, prioritize **OEM or high-quality aftermarket parts** (e.g., from brands like **Suzuki Performance Parts, Dirt Bike Parts Store, or reputable custom shops**) to ensure longevity and performance. Always weigh the cost of the parts against the potential savings of a full rebuild to make an informed decision.
