Some maintenance items need more frequent service if you are riding in unusually wet, dusty, sandy or
muddy areas, or at full-throttle.

Every two years replace the internal components of the brake master cylinders and calipers, and
change the brake fluid.
Replace the brake hoses every four years and if cracked or damaged.
