Hi - I see that, like me, you have been seduced by the good looks of the QJ150. I searched in vain for some useful info or ride reports both here and elsewhere, but in the end took the plunge based on intuition and a couple of test rides from different sellers. I only got it a couple of weeks ago, and still running-in so sadly I can't tell you a great deal, other than it is still going strong. Despite those Italian good looks, it is more of a nongmin che than a thoroughbred underneath, which suits me perfectly, but not the fastest thing on two wheels, and I have already destroyed the pretty lines by putting on the biggest top-box money will buy. I will post a full report of my buying, plating and riding experience once I have had a bit more time on it, but so far (and for the money) it has been a good choice. Like you, I had my heart set on the green one until the moment came to hand over the money, when for some inexplicable reason, I went for the orange one... Will you do the same??
Either way, have fun and ride safe.
