ok its kinda hard to measure with the clip on on it, but its rite at 1 1/4'', the clip ons are 1 1/2''.
That's gonna make for some very twitchy handling. Having said that, it *should* still be acceptable. Stock FZ6 rake is 25 degrees; sport bikes typically have 23-ish. Sliding the legs up 1" should equate to roughly 1 degree reduction, so you're now somewhere over 23. In other words very close to what a full on sport bike feels like.
Very twitchy and less stable, but turn initiation should feel quicker.
