The ultra-light aluminum sprocket reduces inertia and contributes to a quicker response from the transmission — however, be mindful of the specific wear of aluminum sprockets, and ensure regular checks and appropriate lubrication. Suitable for Honda CR 250 R (ME03) models from 1984 and 1985, as well as other models equipped with a 520 pitch and an adjustable number of links.
