Ah, those Germans... so much technical expertise, so much of it wasted on scooters...
Some crazy scooter modifications have come out of Germany, and the average "custom" scooter over there puts anything I've seen in the US to shame. All those crazy high performance goodies off the shelf from SIP exist because there is a huge customer base for them.
Then, you see this:

Wow. Dude just decided to machine himself a whole motor with a CNC machine. Neat! Then he built the scooter around the motor, using a wind tunnel to test for correct air flow around the radiators mounted under the left cowl. The cowl itself was custom designed with crazy louvers for maximum air flow. This is some amazing work, and even more impressive is that he got it road legal in Germany, which is very very difficult for anything custom made.
Kudos to Felix, amazing work man. I love it!
