KTM Adjustable Brake Lever 790/890 Adventure

See that bushing it comes with. You need to remove the bushing from the stock lever and remove part of the lever assembly from the stock lever and then add it to this lever using a press. Good luck doing this at home. I brought it to a machine shop near me to press the old bushing out and move the assembly and the press the new busing into the new lever holding the rest of the lever assembly together. He charged me $10 to do it as it only took him a couple minutes with the press he had.
