Some aspects of motorcycle maintenance are essential to your safety.A late oil change can cause more wear on your engine.The risk of brake failure gets higher if you don't take care of your system.
The magic ingredient that allows you to reduce speed in demanding situations is the brake fluid.
The main difference between DOT 5 and glycol-based fluids is that glycol attracts and absorbs water from the air, so it has a longer service life.
DOT 5 is more expensive than DOT 4.DOT 5 is harmless to painted surfaces, but glycol-based fluids can cause damage to the paint.
Most Harley- Davidson motorcycles use DOT 4 as DOT 5 compressibility.Always use the recommended grade for your motorcycle.
