We looked at a GT+ & MG Mandello last year, as a means of downsizing the stable.
In the end we went with an immaculate low mileage R1250RS Exclusive which seems to tick all the boxes. OK, the 2 year BMW warranty on a premium selection bike helped swing it & I suspect the pricepoint was made more attractive as RS sales had become a tad slow in expectation of a revised 1300.
Otherwise, the Yamaha - a nice ride, but struggles to hide the fact that it's derived from a much cheaper base model in some areas.
Then the Mandello - I saw far too many demo bikes with paint quality issues - mainly engine & gearbox. Flaking, bubbling with corrosion, colour mismatch - Hopefully it has been addressed on later bikes. We all know even the mothership has issues after all.
