This kit contains everything you need to gain control of the rear brake with a left handed lever while maintaining all the function of your foot pedal and rear caliper. Unlike Thumb-operated rear brake systems, that typically offer about 25% braking force, our system is able to deliver approx. 90% of pedal-operated braking force. This is a true left handed brake master cylinder with enclosed brake resevoir- not one that is turned upside down. And this system does not require any additional brake caliper be welded on or otherwise added. Kit Includes: Left Handed Master Cylinder/Resevoir Rubber Coated Stainless Line Machined from Billet Anodized Fitting All Banjos and Crush Washers (PLEASE SPECIFY YEAR AND MODEL OF BIKE OR MOTARD)
