Another clue

Since we had no...responses to the quiz issued the other day, I will offer a clue on..the clue....

IDM is short for Internationale Deutsche Meisterschaft, 
Which is German for International German Championship, it has to do with SuperBikes.

Mister Marcel Niederhausen rode a Ducati 1199 Panigale, but usually rides a Honda CBR1000RR...


Helmet development:
The relationship between Marcel Niederhausen and Schuberth was not merely one between 
customer and manufacturer; with his focused approach to his work and detailed change 

requests he contributed to ongoing enhancement of the helmet. The cooperation ultimately went

 so far that Marcel Niederhausen provided important ideas for further development of the 

Schuberth flip-up helmets. Niederhausen drew "his" ideal flip-up helmet on a napkin during a 

dinner. This was the basis for developing the current C3. The result is the smallest, lightest and 

quietest flip-up helmet in the world. For Niederhausen there is nothing unusual about this: "I 

myself only ride motorcycles when maximum safety is guaranteed. Consequently I also help 

Schuberth in developing motorcycle helmets which are designed to be even safer and better:

 so that every motorcyclist on the road also benefits from them."
