This thread is really old, but someone was reading it. I got curious and looked at it, and have to answer.
First of all, since no-one has explained it, it was probably a play on words. Dyke= an embankment that holds back water. I gather the Netherlands have one or two of them.
Back on topic:
Yamaha Virago, particularly the 535.
The Suzuki Intruder has already been mentioned.
I hardly dare mention the Kawasaki Eliminator series, as I otherwise quite like Kawasaki bikes.
I could go on, but if I did, I wouldn't be able to avoid mentioning a Hardly Driveable model or two, and that might offend someone, so I wont.
