Certainly sounds it to me! Give Tamworth Yamaha a call, I happened to see an ad for the R1M at 18K (after the YRE experience, old stock effectively), popped down from Derby and unfortunately it sold the night before, but to my amazement they had 4 new R1s for sale at 13K+otr fees unregistered, not even mentioned on their website. Got a 5K trade in on my 2008 R6 too. And good service (better than my local dealer I bought new MT07 from). Point being none of the R1s were advertised, its worth a phone call, it was the same thing with my R6 before that (got a great discount on a bike that wasn't advertised by calling around dealers to ask what they had, bought it with 50 miles on clock for 6K they hadn't got round to advertising it). Everyone delivers these days too. But yeah, that sounds like a good deal you got offered, think I paid almost that for my non abs bike in 2015 (the one bike I paid full price for I was that impressed with it!). You do know there's a new model out this year though? If its the new model its an especially good deal, if not its still a very good bike. I hear they firmed up the suspension on this years bike so it may ride a little taller with less squat?
You could easily skim some foam off but might make the ride unpleasant. I added foam then recovered the KTMs seat (like a plank of wood,worst seat EVER!). You would need an air powered staple gun with short staples to reattach the cover, hand spring powered guns wont penetrate the plastic, I tried before buying air powered one. May be possible just to drop the forks through the yokes a bit too, but that may affect handling & make it a little twitchier by shortening wheelbase slightly (add a link in chain to compensate??). The old adage "where there's a will there's a way" is very true, I have broken both my wrists racing bikes, I have scoliosis & spondylitis and tendon problems in my left arm - but I still bought the R1, have had to buy a downblipper to help my problems & cut & shut some controls etc but there are people who overcome far far worse & continue to ride. I was once overtaken by a one armed guy on an Oulton test day, I wasn't very fast there but this guy was nearing BSB pace, I spent a session on the pit wall laughing in admiration at the guy after that. Seen plenty of other amputees (none anywhere near as fast) on track days too. On the last trackday I did I was dicing with Darley newcomer club champion, he had more metal in his back than Connor Cummins, he was seriously impressive I could only just keep him behind me with my R6 backing in to every corner. So forget worrying about it & get on & buy one would be my considered advice! I'm sure you wont regret it. Let us know how you get on!
