250 km per day for extended periods qualifies as "speedy" in my book, but I've done it in a variety of areas and so can you--as long as nothing major goes wrong. Much depends on how you like to travel, i.e., how many side trips, how much lounging or around exploring specific areas in detail, whether you favor pavement or gravel and dirt.
If you're really a novice, a short trial journey to work out the kinks is always a good idea. And when you say "we," that implies either more than one bike or yourself and a pillion. Either way, multiple people involved tends to slow things down, since everyone's comfort and preferences needs to be taken into account. I'd always suggest having shorter, quicker alternatives or other ways to bail out along the way.
You'll want to have another look at your route (at least) in terms of the Armenia/Azerbaijan border. I know less about Iran, but my American passport would make that part difficult, so worth checking into if you're British. Hardly anyone ever regrets adding as much time to their trip as possible, so if you can do four full months by all means do it.
Hope that's helpful.
