Large-displacement motorcycles require periodic brake fluid replacement to ensure safety

1. How often should brake fluid be replaced?

Compared to motorcycle clutch lubricant, brake fluid replacement for large-displacement motorcycles is often less noticed. However, over time, brake fluid also degrades, accumulates deposits, and causes brake system blockages. If delayed, disc brake performance will decrease and wear gradually.
