Steve - I know what you mean, all my other bikes are bigger - from Motoguzzi's to Ducati's, to old shovel heads.... so this little Van Van is a different world. Yet, it's the first bike I've been jumping on lately!
To answer your question, yes I really have to work it to keep it up there. If the wind is blowing against me, it's even worse. But, the bike just hit 500 miles so I've been not beating it too much. I plan on taking it for another run, then changing the oil. Once I do that I'll hit it much harder and see how it does at top speed. I'm curious to know how fast I can get it. If I can hit 69 or 70 I'll be a happy camper.
