How many rings have you got showing on the front forks and have you done any adjustments to the suspension. Wanted to lower mine but have'nt had the balls in case I mess up the suspension.I'm 5'6" with a 28 inch inseam, I have cranked the rear ride height down almost all the way and run the tubes in the triple clamps up the same amount. Both my feet touch the ground, not quite flat footed. Never measured the overall seat height when I was finished, but it still handles solidly with more than enough travel on either end.
I am about the same height . learning to feel comfortable without being able to touch both feet takes practice and a lots of confidence.I'm 5'3" with a 27" inseam. Learn to ride it as is, no need to put both feet down, any lowering compromises the handling.
There isn'tif the bike sits too tall for your comfort, consider having the seat redone so that it is thinner. take the seat to an upholstery shop or someplace that does custom seats and have them thin it out and maybe use a gel.
a lot easier and much less expensive than lowering the bike.
i admit i have not looked at the seat close enough to see if there is enough seat to make it thinner, its just a thought.
I, too, am inseam challenged. The first two things I changed with my Brutale were (1) more comfy seats and (2) lowering the ride height.
The item I purchased helped with the seat height (perhaps 3/4 - 1 inch lower) is Sato Racing Adjustable Suspension Link Rod. I happened to purchase it thru ebay from a fellow MV owner for about $50, but I think you can purchase it new for $85 at their site. The part is just the double-threaded link with the hex portion in the middle.
Basically, the link works because the hex drive portion in the middle is thinner (areas without the thread), allowing the top link and bottom link to get closer than stock. The total top+bottom link is shortened by about 1/4 - 1/2 inch, which relates to a bit more at the seat.
As a fellow inseam-challenged, I highly recommend it.
I think there is a fancier titanium version of the same thing by anther manufacturer, but functionally, it does the same thing. (but costs about $250 ea. Jeeze!)
I did something similar on a cbr f4i and it lowered it about an inch.Made a huge difference and I cannot tell about the handling ,but seems okay.
Did you also raise the the forks about the same?
I am not sure the 910r has the link.
I have a thin tush and the seat is thin. What help on the last trip i put on Canali bicycle shorts with gel padding I could go 6-7 hours before MOnkey butt raised its ugly head versus 3 4 max withoutit. The gel is about 1/4 inch only on part of the shorts. Very effective.
I wear my 1.5 inch boots and I can touch both feet,but I must wear the boots. I would give the link mod a try if I can. Thanks I was not aware they existed.
