It wasn't easy to find an interesting motorcycle roadbook for West-Vlaanderen with Diksmuide as destination.
Fortunately there was somebody who put together a google map on motorforum.be.
I used this route planner site to manually reconstruct the itinerary so I could save it to .itn format to be able to use it with my tomtom 930. I also saved .tnr file (see attachment) so you can reload it in this site if you want to easily see the result.
I did not reconstruct it completely, just till Diksmuide.
Can recommend the trip, it was definitely worth it.
