"Radial Master Cylinder 12mm Our Radial Master Cylinder was designed with one goal in mind... Performance. Manufactured to the highest quality standards, this all new Moto-Master product will maximize the performance of your complete brake system through a number of features. While compact in design, this master cylinder uses a forged lever, plate, and cylinder to create a strong feel and great durability. The brake lever position is adjustable allowing it to suit any preference, and an optimal leverage ratio built into the design gives you maximum power with just one finger. In addition the direct pressure point provides great feedback which ensures optimal control. A brake light switch is also available if needed, and as a finishing touch we added an orange anodized and laser etched aluminium filler cap to complete the package. Available in 11mm and 12mm diameter, these master cylinders are designed for MX and Supermoto applications. * Brake light switch sold separately "
