"the only slight issue I had is that the latch mechanism sometimes pulls off the front tang, hence the tie wraps"
You can add some rubber or vinyl strips between the frame and the clamps to prevent the mech from sliding and unlatching.
Also, whoever installed mine obviously didn't measure twice, so only one of the hooks actually engage properly at the back. Good news is, one is all that's needed, or has been all mine has needed at least, as it has never caused an issue for me.
Your pillion will be encouraged to stay close with this seat as filmcamera states, so be ready for more frequent knee squeezes and a warmer lower back... :riding:
