The grips are comfortable and fairly easy to put on, though a bit fiddly. My concern at the time is the screws are a very small diameter and fine thread, I thought they wouldn't hold the two halves of the grips together, but I haven't had any problems with them. My only gripe is the throttle boss I ordered with the grips don't fit the heated grips as the diameter of the heated grips are bigger than standard Kuryakin grips. A bigger throttle boss for heated grips is required.
