OEM Honda CBR250 CBR300 Front Sprocket Lock Plate

This is the genuine OEM Honda Front Sprocket Lock Plate (Part #23802-KYJ-900), also referred to by Honda as the "Fixing Plate." This small but essential component secures the front drive sprocket to the output shaft of the transmission, preventing rotational movement and keeping your chain drive system properly aligned and retained under load.

Over time, this plate can become bent, cracked, or worn — especially after sprocket replacements or high-mileage use. Replacing it with the authentic Honda OEM part ensures the sprocket stays locked in place exactly as it was designed from the factory. This is a recommended replacement any time the front sprocket is serviced, and skipping it can lead to sprocket migration, chain misalignment, and accelerated drivetrain wear.
