I prefer the looks of the low backrest. Yes, you will need to remove the fender bolts. If you have never done it, it can be a *****. Here is what you need to do. Take the front right one out first without touching the others. Put the bolt through the mounting bracket and into the fender and get it started. If it does not start, ie if the fender has shifted, then go ahead and remove ALL the bolts. Now with all the bolts removed, start the front right. You may need to grab the back of the rear fender with your left hand and move it around to lign up the hole. Good Luck!
