FAQs
What is the main benefit of buying a chain and sprocket kit instead of individual parts?
The primary benefit is convenience and cost-effectiveness. Kits ensure all components are compatible and designed to work together, and they are typically priced lower than purchasing each item separately. They also simplify the selection process by providing a complete drivetrain solution for your specific motorcycle.
Does this kit come with a specific gearing ratio?
Yes, these kits are supplied with the standard gearing configuration for the motorcycle model they are designed for. This means they will maintain the original performance characteristics of your bike.
What type of maintenance is required for this kit?
Regular cleaning and lubrication are essential. You should clean the chain with a degreaser and apply chain lubricant regularly, typically every 300-500 miles or after riding in wet conditions. Chain tension should also be checked and adjusted periodically.
Can I use this kit for aggressive riding or racing?
While the RK chain and Afam sprockets offer good durability for standard road use, they are designed with standard gearing. For specialized performance needs or racing, you might consider kits with different gearing ratios or higher-spec chains designed for extreme conditions.
What tools are needed to install the chain?
Installing the chain requires cutting it to length and joining it with a master link. This typically requires a chain breaker tool and a chain riveting tool (for press-fit master links). Professional installation is recommended if you do not have these specialized tools.
How long should I expect the chain and sprockets to last?
The lifespan varies greatly depending on maintenance, riding style, and conditions. With proper care, a well-maintained RK upgraded kit can last for tens of thousands of miles on many motorcycles, often outlasting standard OEM components.
What does '428 Pitch' mean for the chain?
Pitch refers to the distance between the pins of a motorcycle chain. A 428 pitch chain is a specific size and width, and it must match the sprocket teeth designed for that pitch. This kit specifies the correct pitch for the intended motorcycle.
Troubleshooting
Chain skips or feels rough
Ensure the chain is properly lubricated and free from dirt or debris. Check for correct chain tension; too tight or too loose can cause roughness. Inspect the chain and sprockets for excessive wear or damage.
New chain is too long or too short
The chain must be cut to the precise length specified for your motorcycle model. If cut incorrectly, a new chain may be required. Ensure you are using the correct procedure and tools for cutting and joining the chain.
Sprockets show premature wear
Verify that the chain is correctly aligned and tensioned. Ensure proper lubrication is being applied regularly. Incompatible chain or sprockets, or riding conditions (e.g., heavy dirt, extreme stress), can accelerate wear.
Difficulty installing the master link
Use the correct chain riveting tool and ensure the master link pins are properly seated and riveted according to the tool manufacturer's instructions. Do not force the link; ensure it is aligned correctly before pressing the pins.

Setup, Compatibility & Care
Compatibility: Always verify that the specific RK Upgraded Chain & Sprocket Kit matches your motorcycle's make, model, and year. The product description and kit details will specify the exact fitment. These kits are designed for specific applications, so ensuring correct fitment is crucial.
Setup: The kit includes bike-specific front and rear sprockets along with an open-ended drive chain. Installation requires proper motorcycle maintenance tools and knowledge. The chain will need to be cut to the correct length and joined using a specialized chain tool and rivet master link (often included or sold separately). It is highly recommended to consult your motorcycle's service manual for detailed installation procedures or seek professional installation if you are not experienced.
Care: Regular cleaning and lubrication are essential for maximizing the lifespan of your chain and sprockets. Clean the chain periodically with a degreaser and a soft brush, then rinse and dry thoroughly. Apply a quality motorcycle chain lubricant evenly to the rollers while rotating the rear wheel. Check chain tension regularly according to your motorcycle manufacturer's specifications and adjust as needed. Inspect sprockets for wear, such as hooked teeth, and replace the chain and sprockets as a set when significant wear is detected.
