My experience with the passenger seat tells me that if you insert them fully they will not come back out. Basically, Kawi didn't install them right. I lost BOTH of them on my seat within a week of owning the bike. There was adhesive around them that was clearly meant to secure them as a secondary measure. When the dealer replaced them under warranty I twisted and twisted until cone pieces snapped fully into the holes on the passenger seat. Then, I drove 12,000 miles, using the helmet hooks under the seat up to several times a day and never had a problem since. I didn't even add more adhesive. It was pretty hard to get them all the way in. It even seems like it's impossible to fit them but I assure you that it is. The rubber cone pieces just seem too fat to fit and the stem seems like it compresses too easily to force it. IIRC, I just smashed it down HARD and repeatedly twisted.
I even asked on Kawi forums and many people never realized that there was supposed to be rubber dampers there.
