Motorcycle parking at airports

The free motorcycle/bicycle park at Brussels is close to the bus terminus at Level 0 (P15?). Enter the airport from the ring, bear right after passing the concrete security barriers, which then takes you on a bridge over the road you just came in on, and then turn right at the T-junction, which then takes you into the bus area. You'll see the bikes.
I also found this list, which may be helpful... http://www.flyertalk.com/forum/travelbuzz/1332950-motorcycle-scooter-par...
