Buyer’s Guide – Factors to Consider Before Purchasing a Final Drive Belt

You should take into account the following things when buying a final drive belt for your Harley:


Make sure the drive belt you buy is compatible with the model of your bike. Take precise dimensions of your current drive belt and contrast them with the one you intend to purchase. Don’t forget to verify the necessary tooth count.

Consult the user manual if you’re unsure of the dimensions.


Always verify the drive belts’ manufacture material. Drive belts made of neoprene rubber and carbon fibre are some of the best available right now.

These days, carbon fibre, a very resilient material with great tensile strength, is frequently used to make drive belts. Earlier belts were often constructed of aramid. However, because to its lower tensile strength, this material has lost favour with certain riders.

Drive belts made of cotton or rubber are less likely to abrade. This indicates that they don’t deteriorate as rapidly. These driving belts run quietly and efficiently. Neoprene rubber also keeps its moisture for a very long period. Drive belts manufactured of this material won’t require regular lubrication as a consequence.

When it comes time to replace your drive belts, choose items made of these cutting-edge materials. Although the initial cost may hurt your wallet, the long-term benefits will be for both you and your bike.


Is your current drive belt requiring frequent cleaning and adjustments? Consider upgrading to a low-maintenance model for better performance. Neoprene rubber and carbon fiber belts are the ideal choice, as they offer excellent resistance against abrasion, rust, and chemicals. With such durable materials, you can expect your drive belt to last until you reach the impressive milestone of 100,000 miles before needing a replacement.

Optimizing Cost and Efficiency

Finding the right balance between cost and quality is crucial. While sticking to a budget is important, investing in high-quality motorcycle parts from reputable brands is a wise decision. This not only ensures optimal performance for your bike but also enhances your safety on the road. If you have budget constraints, aim to purchase an affordable drive belt with OEM quality to meet your needs.

Beware of the Pitfalls of Cheap Belts

Although cheap and flimsy belts may seem like a money-saving option initially, they fail to withstand the demands of your Harley in the long run. In fact, these inferior belts can potentially snap while you’re riding, leading to accidents and unexpected disruptions. By investing in a top-notch belt, you can enjoy years of reliable service and ultimately save more money over time.

The Importance of Replacing the Final Drive Belt on Your Harley Davidson

Replacing your drive belt becomes evident when it suddenly snaps, forcing you to halt your journey. However, there are additional conditions under which you should consider changing your rear-drive belt:


The drive belt on a Harley generally needs less care and upkeep than other bike components. Even so, it is still susceptible to normal wear and tear. A high-quality drive belt rarely has to be cleaned and lubricated. However, you should check the state and tension of your belt after a few thousand kilometres.


Are you fond of adventurous journeys along bumpy roads or gravel paths? Perhaps you’ve recently encountered a deep pothole that could potentially harm your bike. Even a small pebble can puncture your drive belt, resulting in the need for a replacement.

It’s essential to ensure that the tension in your belt is not excessive, as this can accelerate its wear and potentially cause it to ratchet.


Certain Harley drive belts tend to produce excessive noise during operation, often due to the accumulation of dust and dirt. Other potential causes include:

– Belt misalignment
– Natural wear and tear
– Air pockets between the belt and pulleys

In most cases, this noise can be eliminated through regular cleaning and basic maintenance. However, if the issue persists even after a thorough tune-up and cleaning, it may be necessary to replace the drive belt.

Understanding the Distinction Between Chain Drives and Drive Belts

You’ve likely encountered the terms “chain drives” and “drive belts” before, both of which serve the primary purpose of propelling or moving a bike. What sets them apart is their structural differences.


In theory, chain drives offer greater strength and durability compared to drive belts, which is why they are often favored in automobiles, military tanks, and mining equipment.

However, chain drives require more frequent lubrication and maintenance. Additionally, they are notorious for getting entangled or jammed while the bike is in motion.


Drive belts are essential components in many vehicles, including motorcycles like Harley Davidson models. In this article, we will explore the advantages of drive belts made from rubber and carbon fiber, their superior durability, low-maintenance requirements, and how to properly inspect them for wear and tear.

Benefits of Rubber and Carbon Fiber Drive Belts: Rubber and carbon fiber have revolutionized the drive belt industry, offering exceptional durability and reduced maintenance needs. Unlike their predecessors, these modern materials eliminate the need for frequent adjustments and lubrication. Additionally, drive belts made from rubber and carbon fiber are cleaner and quieter, providing a more enjoyable riding experience. However, it’s important to note that they are still susceptible to slipping or snapping.

Distinguishing Drive Belts from Chain Drives: It is crucial not to confuse drive belts with chain drives. While chain drives were once popular, Harley Davidson has embraced the use of drive belts in their models since 1980. Today, most Harleys utilize drive belts due to their numerous advantages.

Frequently Asked Questions:

  1. How often should I inspect my drive belt?

After installing a new drive belt, it’s recommended to inspect it once your bike has covered the first 1,000 miles. This inspection can be done personally or by a qualified mechanic. During the inspection, ensure that the drive belt’s tension is correct and check for any visible tears or holes that could potentially cause the belt to snap. After the initial inspection, subsequent checks should be performed after each oil change or when the bike completes 5,000 miles. These regular inspections are vital to maintain the optimal performance of your drive belts.

     2. How can I check my drive belt for wear and tear?

To inspect your drive belt, simply rotate the back wheel and carefully examine both the inner and outer surfaces. Look for signs of wear such as tears, holes, broken teeth, chipping, or cracks. Minor scratches and nicks are generally not a cause for concern. However, if you notice significant damage such as holes or gashes, it is advisable to replace the drive belt promptly. Additionally, pay attention to the condition of the pulleys. For chromed pulleys, ensure that the surface materials do not flake off, as drive belts rely on the durability and longevity of materials like rubber and carbon fiber.

How Can I Make My Drive Belt Last Longer?

To ensure your drive belt enjoys a prolonged life span, follow these practical steps: ● Gently store the new drive belt, avoiding backward bending or forming a circle smaller than 5 inches. ● Refer to the user manual before lubrication to determine if it is necessary for your specific belt. ● Regularly inspect your bike if you frequently navigate debris-filled roads. ● During reinstallation, ensure old belts rotate in their original direction.

What Causes a Drive Belt to Slip?

Drive belt slippage can occur due to various reasons, including: ● Excessive lubrication ● Misalignment ● Insufficient or excessive tension ● Incorrect belt size for the bike model

When Should I Lubricate the Drive Belt?

Modern drive belts often come pre-lubricated, eliminating the need for additional lubrication. These belts retain natural moisture for an extended period, reducing the likelihood of slippage. Instead of adding unnecessary lubrication, focus on realigning or adjusting the belt’s tension if required.

How Do I Know if the Drive Belt Is Too Tight?

Use a belt tension gauge to ascertain the proper tension for your Harley’s drive belt. Avoid loose drive belts, as they are prone to snapping, especially when your engine boasts high horsepower. In such cases, tightening the drive belt appropriately becomes crucial for optimal performance.

By adhering to these suggestions, you can significantly improve the performance and lifespan of your drive belt, contributing to a smoother and more enjoyable riding experience.

How Much Does It Cost to Replace a Drive Belt?
Depending on the bike model and your source, this may be. Some motorcyclists claim that although dealers sometimes charge extra, they may give you a discount if you’re a regular client. Online, you may discover incredible discounts on drive belts.
You must pay the mechanic’s fees if you bring your Harley to a shop for repairs. To avoid paying fees, change the drive belt in your garage at home.ConclusionDo your homework before making a drive belt purchase. Examining reviews on motorcycle forums and independent websites is a great approach to find accurate information.

Drive belts are a crucial component of your motorbike even if they may not require frequent inspection or replacement.
