Lowering kit is no good?

My friend is going to do this to his CBR600RR. He's around 5'5" or so. The 600RR is real tall. Taller than even my Superbikes, which although not flatfooted I don't feel uncomfortable on even though I'm a veritically challenged 5'7".

When my friend asked his friends at the local Honda dealership about what's called I think a "T-bone" the only effects they mentioned were ground clearance if you were taking it to the track. But since he's gonna use it for street riding it won't be an issue.

When I was looking to get a new bike to upgrade from my CBR600F2 back in late 2003 I was looking real hard at a 600RR. I could get one at the time from a local dealer for like $7200 plus taxes,etc. The main reason I didn't get it is because it was too tall for me. The other reason was that I realized for a bit more I could get a freakin Ducati. Woohoo!!

Not to sound stereotypical and hopefully not offend others but I can understand a Ducati being somewhat low and made for smaller riders. I mean I think Italians are generally shorter than for instance Americans. Now when you go to Japanese bikes you would think the same thing. I mean, once again excuse my ignorance if I'm wrong and sounding stereotypical, aren't Japanese people generally smaller than American people? If so then maybe the Japanese manufacturers tailor their bikes more to Americans?
