Renthal Ultralight Rear Sprocket - 55T Red

The primary advantage is reduced rotational mass, which leads to improved acceleration, quicker throttle response, and a more agile feel for the rider.

This specific model (189U-420-55GRRD) uses a 420 chain pitch.

It is recommended to clean and lubricate your chain and sprocket regularly, especially after riding in wet or muddy conditions, or after washing the motorcycle. A good rule of thumb is every 300-500 miles, or more frequently for aggressive riding.

While possible, it is generally recommended to use sprockets and chains from the same manufacturer or a matched set to ensure optimal performance, durability, and compatibility.

'55T' refers to the number of teeth on the sprocket, which is 55. This is a common specification that affects gear ratio and performance characteristics.

Typically, ultralight sprockets are sold individually and may not include new hardware. It is advisable to check the product packaging or consult the retailer. Using new, high-quality hardware is often recommended during sprocket replacement.

Verify that your motorcycle model and year are listed in the compatibility section. Ensure you are using the correct chain pitch (420 for this sprocket).

Check chain alignment and tension. Ensure the chain is properly lubricated and not worn. Inspect sprocket teeth for premature wear.

Ensure proper chain tension and lubrication. Avoid riding with a damaged or worn chain, as this will accelerate sprocket wear. Clean the drivetrain regularly.

Ensure the sprocket hub is clean and free of debris. Consult your motorcycle's service manual for specific installation procedures and torque specifications.
