Is this something different from a slider or frame saver????Ted Edwards said:Easy,
A 'magis mushroom' is a lump of plastic that looks a bit like a mushroom, it fits to the side of the bike inside the fairing. (Usually bolted to the frame rails).The idea behind it is when you fall off it will save the engine and reduce the damage to the fairing. However, if you have a big one it may also cause damage to the frame as well!
