Are There Benefits to Using Aftermarket Motorcycle Parts Over OEM Parts?

Choosing between aftermarket and OEM motorcycle parts is a decision that requires careful consideration. While aftermarket parts can sometimes offer certain advantages, they also come with potential drawbacks. This article explores the pros and cons of using aftermarket parts and provides real-world examples to illustrate the points.

Understanding the Difference: OEM vs. Aftermarket

Before delving into the benefits and downsides, it's important to understand the difference between OEM (Original Equipment Manufacturer) parts and aftermarket parts. OEM parts are designed and manufactured by the motorcycle manufacturer to fit their specific models, while aftermarket parts are produced by third-party companies and designed to meet specific needs or offer enhanced performance.

Possible Pros with Aftermarket Motorcycle Parts

Higher Quality: Aftermarket parts can sometimes offer superior materials and construction methods, resulting in higher quality and durability. Lower Price: Many aftermarket parts are priced lower than their OEM counterparts, making them a more cost-effective choice. Better Performance: Aftermarket parts can provide enhanced performance and handling, such as improved exhaust systems or upgraded suspension. Longer Lasting: Some aftermarket parts are designed to be more durable and resistant to wear and tear, potentially lasting longer than OEM parts.

Possible Cons with Aftermarket Motorcycle Parts

Lower Quality: Some aftermarket parts may be lower quality and less reliable than OEM parts, leading to potential issues with performance or durability. Higher Price: While some aftermarket parts are cheaper, others can be more expensive, making them a less attractive option for cost-conscious buyers. Lower Performance: In some cases, aftermarket parts may not perform as well as OEM parts, especially in terms of reliability and longevity. Shorter Lasting: Some aftermarket parts may have a shorter lifespan compared to OEM parts, requiring more frequent replacement.

Real-Life Examples and Insights

Let's explore some real-life examples to illustrate the benefits and downsides of aftermarket motorcycle parts.

Exhaust Systems: A Case Study

Exhaust systems can be a prime example where aftermarket parts outperform OEM parts. OEM exhaust systems are often heavier, less efficient, and more expensive than their aftermarket counterparts. For instance, on a 1st generation Suzuki Hayabusa, the OEM exhaust system was a 4-2-1 design, which was:

Heavier: Every component was more substantial, with one can weighing more than the entire aftermarket system. Less Efficient: The header pipes were small and heavy, compromising performance. More Expensive: Replacing the OEM exhaust system would have been significantly more costly.

On the other hand, the aftermarket system chosen by the author, the legendary Brock Davidson Engineering Gen III, offered:

3-step thin-wall stainless steel header pipes 4-2-1 design Titanium can (for reduced weight and enhanced performance)

The total cost for the exhaust system, along with additional kits and improvements, amounted to around $1000. This compares favorably to the significant cost of the OEM exhaust system, making the aftermarket option a clear winner in terms of quality, price, performance, and longevity.

Fasteners: A Different Perspective

Fasteners are another area where OEM parts often outperform aftermarket parts. Fasteners like bolts, nuts, and screws are critical components that can affect the overall performance and reliability of a motorcycle. For Japanese brands, the quality of OEM fasteners is generally superior, and they are rarely surpassed by aftermarket alternatives. The author provides a real-life example where an aftermarket fastener was inferior to the OEM part, highlighting the importance of using the original equipment:

Triple the Best Quality: OEM fasteners are often more durable, have better corrosion resistance, and last longer than their aftermarket counterparts. Availability and Durability: OEM fasteners are specifically designed for their intended use, ensuring longevity and reliability.

For the author, using OEM fasteners was the preferred choice, especially when they lost a couple of fasteners. The solution? Directly purchasing OEM parts through an authorized dealer or online retailer ensures the best fit and performance.

Conclusion

There is no easy answer to the question of which parts to use, be they OEM or aftermarket. Every case is unique, and it’s essential to do thorough research and make informed decisions based on specific needs and desired outcomes.

In summary:

Consider the quality, price, performance, and durability of each option. Understand the specific needs of your motorcycle. Do your homework and compare different options.

Ultimately, whether you choose OEM or aftermarket parts depends on your budget, performance goals, and specific requirements. By understanding the nuances, you can make a well-informed decision that benefits your motorcycle and riding experience.
