Call me old, but the BMW F engine is just not as engaging as an angry 4 cylinder. There is something primal about revving the shite out of a highly strung N/A 4 cylinder.
I did enjoy riding an F800, it sort of sounded like a very refined V2 and made plenty of power, but it didn't fill the hoon gland up like a Z900. Maybe the naked one would do power wheelies easier than the F800 that I rode, it was a bit of an old farts tourer.
The triple is a whole other story, those Triumphs are a peach of an engine, just too damn expensive to repair and service in Australia for my tastes.
