Really nice on my 2014 honda shadow spirit. No pre drilled holes. You will have to pre drill holes for the kill switch clamp and head light switch clamp. Paint was thick for my throttle grips and wouldn't throttle smoothly. I had to sand down about 1 1/2 from the throttle grip almost to bare metal to have the throttle grips roll smoothly. But overall, feels and ride good with the 10' rise bars.
