For 2019+ Honda CRF110 installs you will need to mount next to the throttle housing and rotate the housing to move the throttle limiting screw out of the way of the lever. Then mount the switch assembly next to the perch.
This is a clutch lever not a brake make sure you go to the asv website and check fitment per your machine. The product is very nice but now I am in the process of swapping or returning this item. It says BDC605 but ends in SX the new Honda’s end with PX. I ended up with a clutch lever.
Not a Chinese copy, the real USA made part which made the brakes as good as they can be for drum brakes.
