If I remember correctly that clamp reduces the trail about 4". Like I said, it must be a good change 'cuz its still on the bike. Its been on for a long time now, and, that monster handles like a crotch rocket to me. I don't scrape the pegs like I used to, but, the youngster in me still surfaces every now and again.
I'm a real big Ducati fan but figured one would kill me today, so, I'm sticking with some comfortable performance.
So the Valk is now less "cruisy" and more turny? Less trail to me means less rake to the forks and a more nimble bike which may or may not be as steady as it was in a striaght line...depends on the bike and damping. The OP is looking at more rake. I did not realise there were TTs that decreased rake.
