Hi Val, your MT09 is a 2015 yes? Have you had the bike from new? What sort of mileage has it done? And has it allways run wild at the back under reasonably heavy front braking? Or is it a new thing that's just started? If it is a new thing what have you done differently or what has changed (fallen off it hit a kerb hard) Lots of questions I know but a bit of background history is always good.
I bought an Ambasador 250cc (Villiers two-stroke twin) years ago that had really weird handling characteristics, it was like riding a ruptured camel (not that I have any evindence that a ruptured camel handles poorly) but it transpired that it had been in a front end shunt and although had been repaired well, the steering head tube on the frame was bent out of alinement, slightly to one side and the handling was awful. Looking at the bike from the front when on the centre stand you could actually see that this single frame downtube did not run centrally between the fork legs.
Back wheel bearings maybe? Under power the chain pull will keep the wheel in alinement, slam the throttle shut and maybe the wheel can slap about, it would not take much to upset the dynamics.
