A forged radial master cylinder equipped with a proprietary variable ratio lever. The fulcrum and action point of the lever can be adjusted in increments of 0.25mm up to 2mm, and the brake touch, which was influenced by the combination with the caliper, can be brought closer to the best condition.
In addition, three types of clamp types (four types of brakes) and two types of lever sizes are set so that they can be matched to the preference of the mounted vehicle and individual rider. All combination patterns are standard equipment, reducing the hassle of purchasing options.
