Assuming it's a V7 744 not 850 seat.. though I suspect it might be the latter, in which case ignore the following.
------------------------
More than likely it will fit and is easier than trying to fit an earlier seat to a later bike, where fuses and mudguard type can foul the seat pan.
At worst, you may need to shave a little off the pan in select places for clearance but probably not required.
I have four (now five) seats from various models than fit on a V7III and though I haven't tried, I'm confident they will also fit the newly arrived V7(I). In fact, I intend trying out a Low Comfort Gel seat on the V7 Classic.
I don't have a V7II but find it doubtful there will be issues.
------------------------
Someone with the poorly named V7 850 may know the answer, if applicable.
