Definition
T6 indicates a heat-treated condition that helps the alloy achieve useful strength for motorcycle parts.
Knowledge base
7075-T6 aluminium sprocket
7075-T6 aluminium is a high-strength alloy often used for lightweight rear sprockets. It reduces rotating mass, but it usually wears faster than steel in harsh dirt use.
Practical use
Aluminium rear sprockets are a good fit when response and lower rotating mass matter more than maximum wear life.
Material notes
Anodizing, tooth profile, and hub design matter. The sprocket still has to match chain pitch and fitment.
Common mistakes
- Choosing aluminium for an application that needs long wear intervals.
- Comparing weight savings without checking chain pitch and hub geometry.
- Assuming a rear sprocket material choice fixes a fitment problem.
