From memory of my old F2 (Shirley). God rest her soul.
Sit on your bike. Put the key in the ignition. Now, under your hand. You see that flat piece of metal running left to right about 8 inches wide (side to side of the bike)? It should have a little depressed area the size of a stamp with the Honda logo in it? That is the upper triple clamp. Provides upper support for the forks which stick up out of the triple.
Forks are the shafts that go from the wheel to the triple clamp for suspension. You prolly know that but just to prep for the clip on explanation.
Clip-ons. You know the bars that rubber handles are on? The "handle bars"? Well, clip ons replace the metal bars inside the rubber grips and the metal block that is attached to the fork. Clip-ons are actually 2 parts, the bars and the chunk that slips onto the forks. Clip-ons allow you to replace the bar that the controls are attached to. If you wreck, hopefully, only the bar will break/bend and can be replaced quicker and cheaper than a stock bar.
you are correct
