This is the vacuum model, and not the electronic? Please confirm.
IMHO, it can be fitted no problem, though I know Mr T doesn't recommend it and so many dealers will not fit. However their explanations have seldom been satisfactory, because I know some post 2016 Tiger riders have fitted and run it no problem.
I suspect that Mr T doesn't really like it (the vacuum model) because if you don't get the adjustment right, you can over-oil the rear chain, and on the Sports Mr T decided to locate the rear disk right next to the chain. So excessive oiling could in theory get onto the brake disk (though of course Mr T would never admit to such a design error). I've never had the problem, even when oiling level set to the point where it splashes everywhere else (ps. my Sport is pre RBW).
I believe that an electronic version is considered OK, which IMHO tends to confirm my suspicions, since it's easier to control the flow on the electronic ones. But on the vacuum one, as long as fitted correctly, you shouldn't really have a problem.
