Brake Fluids

Motorcycle Brake Fluid – Choose the Right Hydraulic Fluid for Maximum Stopping Power

Brake fluid is one of the most critical safety components on your motorcycle. Here you’ll find premium DOT 4, DOT 5.1 and racing brake fluids engineered for stable braking, fast ABS response and reliable performance under extreme heat.

Which brake fluid should you choose?

The easiest way is to check the reservoir cap or your owner’s manual. Most modern motorcycles use glycol-based fluids – typically DOT 4 or DOT 5.1.

DOT classes for motorcycles

DOT 4 – Standard choice for road, touring and offroad.
DOT 5.1 – Higher boiling point and lower viscosity. Ideal for ABS.
Racing / Super DOT 4 – Extreme boiling points for track use.
DOT 5 (Silicone) – Never mix with DOT 4/5.1. Used only in vintage bikes and some Harley models.
