Hello, I'm Maurizio from the italian GRANPASSO.EU forum.
In important that you check your swingarm (Granpasso, Scrambler, 1200 Sport) and look for fractures, because it could break near the ohlins shock.
The university of Stuttgart, Germany, found that the broken part is poorly developed and manufactured.
Here you can follow the discussion.

Many thanks Maurizio!

That's an important warning for safety!! Any idea if the factory has a solution for this?

Factory was informed in June 2014, but we are not aware of any solution.

One of our best Morini mechanic in Italy told us that he don't believe that the problem was a poor develop (as written in the university report), but instead he stress that the problem was a bad welding.

If you look at your welding at it has a concave form, you may experience the fracture of the swingarm.
A concave welding means that the two part of the swingarm were too far during the welding process.

The welding must be convex.
Check also for fracture of the welding.

Now we have reports of a total 8 bikes with a broken swingarm (4 in Italy, 3 in Germany, 1 in Netherlands).
We think it's about 1% of all Granpasso, Scrambler and Sport.

This is another broken swingarm from a member of our forum.

Hi Maurizio, I sent the dealer that had the GP in NL a message, but no reply so far :(

I'll check on my Scrambler if there are any troubles visible...
