Got these Crash mushrooms, hopefully I will never try them out .quality is is very good. Not like the R&G 2nd skin . & look Well on the bike. Instructions are very poor,threw them in the bin .
Very well manufactured, reasonably stylish (as much as bolting chunks of plastic to the side of a motorcycle can be!) and a great fit. I needed a thin walled socket and a good torque wrench to fit. Fitting is easy but you need the correct tools.
If you have a very vivid immagination you could also say they almost look like MotoGP style 'wings'.
