Put simply (& apologies if this is covered elsewhere) - are there any real mechanical differences between the first and last models of 900s?
I'm more than happy with my 02 but shortly it won't be allowed into London's ULEZ zone without a charge (different topic, don't get me started...) which made me look more closely at a later model.
My old man used to say 'always buy the last of an old model as the faults will be ironed out by then' so apart from known issues such as ECU, camchain tensioner, TPS etc (http://www.tdm-yamah...ex.php?page=ISS) and the addition of a wired-in immobiliser and ABS; are the outgoing models significantly different or better than the early ones?
Even Yamaha's own page: https://www.yamaha-motor.eu/designcafe/en/about-bikes/sport-touring/index.aspx?view=article&id=442659&segment=&archive=false&page=2 is littered with inaccuracies - it shows my 02 as having a 190 rear tyre...it doesn't. On the plus side mine does apparently make 0.6hp more than the outgoing one. Oooh!
