NakeDJ, I would ask the dealer how he plans on lowering the bike. I would find out if it is easily reversible. I am sure when she get used to the bike and wants better performance she, would want you to lift it back to its original form. A female friend of mine had the same problem; I wondered why she wanted it lowered because she was only 2 inches shorter than me. But when my fat ass sat on the bike it dropped, and when she sat on it it didn’t. She rides a Busa now but that’s getting off the subject.
As for the 109R man that is a beautiful bike. I got to sit on one at Rizzon a Suzuki dealer close to me in Jersey, and yes it is a monster. I liked the sitting position and the bike was definitely well balance (it felt deceitfully light). Did you get a test ride??
