Honda Brake Lever ( for Spline)
So you've put on your rearset but don't know how you will actuate your rear brake drum lever? This part has a spline and slips over the spline shaft sticking out. So connect your rearset lever to this guy and your good to go.
***77-78 CB750K model arm does not have provision for stock brake light switch. A new location will need to be found.***
