Paul, I currently have 2-2010s, virtual Black on Black clones, each has close to 10,000 miles on the clocks and they're completely different as to handling and there is no denying it. I've treated them as an Arab treats multiple wives, if one was upgraded, the other got exactly the same. Heck, they're not even that far apart on the VIN #s. All you can do is adjust yourself to what you're riding and really, it's all good.
