I'm interested to see what people think...Redmist on here has a set of the ones that come through the fairing. He drilled holes in his track fairings but not in his standard red fairings.
I had a look at his 749 the other day and thought that this was a pretty good idea. Without the mushrooms the bike looks pretty but you have the piece of mind.
The fitment under the fairing is so big without the plastic mushroom it looked like it will protect the frame and engine if you had a road crash...when he put on his track fairings he screwed on the extension mushroom, therefore protecting the track fairing as well as the frame and engine.
