Important Notes
– All our drive kits include X-ring sealed chains specifically tailored to fit the designated bike model.
– Proper chain tension for all contemporary sport bikes should allow for a minimum of 2 inches of vertical movement to account for full suspension articulation, thereby averting premature chain elongation and sprocket deterioration.
– Round hole or solid (no holes) designs typically ship within 1-2 weeks.
– Custom designs typically ship within 3-4 weeks.

FAQ About Harley Davidson Sprockets
No, Harley-Davidson rear sprockets do not fit all motorcycle wheels. Sprocket installation depends on the specific model and brand of motorcycle, as well as the type and size of the rear wheel. Harley-Davidson motorcycles have their own unique sprocket design and specifications, specifically for the rear wheel. Therefore, it is important to ensure that you purchase the correct sprocket for your specific Harley-Davidson motorcycle model and rear wheel.
If you are unsure about the compatibility of a sprocket with your motorcycle, it is recommended that you consult MPM’s professional motorcycle engineers who can provide you with the necessary information and guidance to ensure you purchase the correct sprocket for your motorcycle.
The best sprockets for a motorcycle depend on several factors, including the specific model and make of the bike, the type of riding you do, and your personal preferences. Here are some general considerations to help you choose sprockets that are suitable for your motorcycle:
Compatibility: First and foremost, you need to ensure that the sprockets are compatible with your motorcycle’s model and year. Different bikes have different sprocket sizes and patterns, so it’s crucial to get the right fit.
Material: Sprockets are typically made from steel or aluminum. Steel sprockets are generally more durable and longer-lasting, while aluminum sprockets are lighter and may offer some performance advantages. Choose the material based on your needs and riding style.
Gearing: The gearing of your sprockets affects how your motorcycle accelerates and top speeds. A higher number of teeth on the rear sprocket will give you more acceleration but may reduce top speed, while a lower number of teeth will increase top speed but may sacrifice acceleration. Adjusting your gearing can help optimize performance for your riding style and needs.
Durability: Look for sprockets that are known for their durability and reliability. Well-made sprockets will last longer and perform better over time.
Cost: Sprockets range in price depending on quality, material, and brand. While it’s important to consider cost, remember that cheaper sprockets may not offer the same level of performance or durability as more expensive options.
Brand and Reviews: Research different brands and read reviews from other riders to get an idea of which sprockets offer the best performance and value.
It’s also worth noting that some riders may choose to modify their gearing by changing both the front and rear sprockets to achieve a specific performance outcome. This requires careful calculation and may involve additional costs.
The best material for motorcycle sprockets depends on several factors, including durability, weight, and cost. Common materials used for motorcycle sprockets include steel and aluminum.
1. Steel Sprockets
- Durability:
Steel is a strong and durable material that can withstand high torque and loads. Steel sprockets are often able to last longer than other materials, especially in high-performance or heavy-duty applications.
- Cost:
Steel sprockets are generally more affordable than some other materials, making them a popular choice for budget-conscious riders.
2. Aluminum Sprockets
- Weight:
Aluminum is lighter than steel, which can help reduce the overall weight of the motorcycle. Lighter sprockets can potentially improve acceleration and handling.
- Corrosion Resistance:
Aluminum is also resistant to corrosion, which can be beneficial in wet or muddy conditions.
- Cost:
Aluminum sprockets may be more expensive than steel sprockets, but they offer some performance advantages that may justify the higher cost for some riders.
In general, steel sprockets are a good choice for riders who value durability and cost-effectiveness, while aluminum sprockets may be preferred by those who are looking to reduce weight and improve performance. However, it’s important to note that the best material for your sprockets also depends on your specific riding style, the type of motorcycle you have, and your personal preferences.
The rules for motorcycle sprockets usually involve the following aspects:
- Compatibility
The sprocket must be compatible with the make and model of motorcycle. Different motorcycles have different sprocket sizes and specifications, so it is necessary to choose a sprocket suitable for the specific model.
- Number of teeth and ratio
The number of teeth on the sprocket determines the transmission ratio of the motorcycle. The combination of front and rear sprocket teeth affects the acceleration and top speed of the motorcycle. Increasing the number of teeth on the front sprocket or decreasing the number of teeth on the rear sprocket will generally improve acceleration, but may sacrifice some top speed. Conversely, reducing the number of teeth on the front sprocket or increasing the number of teeth on the rear sprocket can increase top speed, but may reduce acceleration. Therefore, sprocket tooth selection needs to be weighed against the rider’s riding style and needs.
- Material
The choice of sprocket material is also critical. Common materials include steel and aluminum. Steel sprockets are generally more durable, while aluminum sprockets are lighter, helping to reduce the overall weight of the motorcycle. The choice of material depends on rider preference and budget.
- Maintenance and Replacement
Sprockets require regular maintenance and inspection. Seriously worn sprockets should be replaced in time to avoid affecting the performance and safety of the motorcycle.
- Installation and Adjustment
Installation and adjustment of sprockets require specialized skills and tools. Improper installation or adjustment can cause the chain to fall off, wear unevenly, or cause other problems. Therefore, it is recommended that professional technicians perform sprocket replacement and adjustment.
In summary, there are several factors to consider when selecting and using a motorcycle sprocket, including compatibility, gear ratio, materials, maintenance, and installation.
