I say get the 848. It is an insanely easy bike to ride in almost every way. Smooth on the TQ and HP when it kicks in, not sudden like a Jap bike, VERY easy to control. I think it would make a great 1st street bike, IF you have the control.
...and I don't mean being in control, I mean self control.
Buy the 848 and you will NEVER even for a second regret it!!!!!!!!!!!!
This is all presuming you have prior experience on other motorcycles or have at least had an MST course. Don't forget, ALL THE GEAR ALL THE TIME!
