I had similar experiences. I bought the five stars crashbows and mounted them
according to the mounting instructions. Afterwards I decided to mount better
horns to my @, so I bought some small electric Fiamm fanfares and mounted it
with the provided small tin pieces (Blechwinkel) to the crashbow. After a few
kilometers one of the mounting pieces broke right around the hole for the
mounting screw due to vibrations, luckily the horn remained hanging at the bike
because the cable plug did not get loose.

A friend of mine made new mounting pieces of 3mm steel and we re-installed both
horns. A few days later this thing broke again.

I decided to mount a big piece of metal (4mm Bandstahl), which goes from the
left side to the right side of the crashbow and which supports the horns
better, is more stable and does not vibrate so much. After two days of riding
the bolt, which is mounted on the horn housing, tore off the housing and the
horn once more was damaged (Die eingenietete Schraube ist mitsamt einigen cm
Blech aus dem Dom des Hupengehäuses 'rausgerissen. Unglaublich, sowas muß man
gesehen haben!). 

Now I was tired of mounting horns to my @ and mounted back the poor original
one (which seems to widthstand the vibrations).

Now, a few months later, I recognize, that one of the metal straps
(Befestigungslaschen), which holds the crashbow, is broken in the middle. I
have to ask a friend of mine, to weld (schweißen) it tight again.

IMHO the vibrations are the biggest disadvantage of the @, right after the
missing 30HP of the engine. ;-)

take care - Marcello.
