What is the point of crash pegs / mushrooms?

I have always thought a) they look cool, and make me look like a racer, and b) if I go down, they'll save my plastics.

But I've heard a couple times recently (once from my suspension guy, who used to road race for a living, and I think once here) to take those things off, because if you crash they will grab the pavement / ground and abruptly stop / redirect the bike, most likely causing it to flip over again...so they actually do more harm than good.

???

Thoughts?

Don't see the point in those. It makes no sense to put such a small piece of plastic or whatever, fix it on to bike's frame and expect that nothing will happen in case of an impact. The stress from the impact has to go somewhere. Also, I think those only save in low speed tipovers, maybe. Don't see how that's worth drilling a hole thru your fairing. That's my opinion.

I didn't answer your poll, but will answer your question.

Its a street bike. Most situations where your bike will be on its side occur at a lower speed. At higher speed, nothing is going to help much.

I've never actually known of a situation where a flipover could be blamed on an XX's crash bungs.

There are mushrooms that attach to the upper side fairing mounts. If your bike tips over with these installed, it will bend the mount or rip it off. I've seen bikes totaled for this problem, as its a frame issue. Later models have replaceable upper side fairing mounts, and you can use those to replace a missing mount on an earlier model XX. The mushrooms will help protect your fairings in the event the bike falls over at a stop sign.

There are also frame mounted crash pegs that require drilling the fairings out. These work quite well. Sometimes I think their mounting point tips the bike so the upper cowl takes more of the force. I'd rather replace a side than an upper.

Mind you, nothing is going to save your fairings if you go down. The crash pads can be the difference between a repair and a replacement, however.

Ideally, I'd have both uppers and lowers, but I've been lazy.

I second adeyr3en in that the beetle bags did get a little gravel rash once in a tip over but last slide out taking off from a corner on a new rear tire actually slid on the bar end, foot peg, and touched the rear cowel and mirror slightly. I removed my big shrooms in the upper fairing mount hole the pior winter just in a weight savings binge. I will say in hind sight there was a phase where i got enjoyment out of them feeling like they were the "in" thing to do. I've since done so many things that are NOT the "in thing" that it doesn't matter any more. HA

I bought some from Jaws, polished em up and slapped em on. Read similar responses and I'm too damn lazy to pull em off.

Thing is, I'm banking on them saving fairings on a parking lot drop at the expense of a bent frame in a moving transaction. But since my mileage low the odds are higher for a low speed drop which is where I see the non frame mounted/requires cutting the plastics useful.

Use your judgement.
