I don't think you specifically said it here, but you do have a lower seat right? You did say you dropped the bike down an inch, but didn't say how.
As stated 17mm shorter shock factory that lowers seat 1" when allowing for the angle of the shock. The stock seat has no rubbers under it so it's as low as the Guzzi low seat. The forks are raised to the fourth line and the side stand has been shortened already. It's all together not enough as far as I'm concerned.
The real question is if the TC, ABS and Lean angle on the 2025 will work without codes. The speedo is useless anyway so I would use a GPS. The one extra inch of shorter height the 17 would give could be a perfect fit.
Yes I would find a full stock wheel somewhere then I'm sure Woodys can get a rim to fit. Using a 120/70/17 would be great for tire choices.
