I have the OEM Crash Bungs aka Roller Protectors.

Is it worthwhile me getting these as well as (or instead of) them?

Additionally: How much do they affect the ground clearance? I'm not into scraping foot-pegs, but will these reduce the angle of lean available?

Additionally additionally: From the Hurt Report: "39. Crash bars are not an effective injury countermeasure; the reduction of injury to the ankle-foot is balanced by increase of injury to the thigh-upper leg, knee, and lower leg."

Hmm...

crash bars provide the best protection for bikes thats why bike schools use them
Im too vain to use them so just have crash bungs

Having done some more reading about them, I'm not sure that they're any better than the crash bungs (and could, in some circumstances, be worse), so I'll stick with the bungs.

My advise is not from reading its from instructing at a bike school

Graham, general consensus is that for a drop at zero speed, the bungs are as good as bars. At any speed, the bungs are just likely to damage the frame, or even cause the bike to pinwheel, causing even more damage. The bars' job is to grind away before the engine does, but because  the force is spread over a larger area, the frame is less likely to be destroyed.

I looked into this a while back and as far as I could see, it depends on the type of bungs.

The OEM Yamaha ones are expensive (£100 a pair) but AIUI they're designed with a weak section that will take the impact, but break before the frame does.

There are others that just bolt directly to the frame which may risk breaking it if the impact is too high.

The bars' job is to grind away before the engine does, but because  the force is spread over a larger area, the frame is less likely to be destroyed.

Yes, but, again from what I've read, that can cause the bike to lever down against the rider's leg, so it might protect the lower leg, but possibly injure the upper leg.

As such, I'm sticking with the bungs (and riding carefully)
