my last bike was an '06 750. in all the track tests, the 750 trounces the 848 in the acceleration/top end department, but the 848 is on par in terms of cornering.
the 848 has the 750 on sex appeal by a longshot IMO. the 848 is just pure sex on wheels.
i would buy the bike depending on how you ride. if you just like to ride, cruise, and pose, then go for the 848 because it will impress everyone at starbucks.
but, if you do trackdays and hard mountain/canyon riding, go with the 750 because it will be alot cheaper to fix when you wreck it. and YOU WILL wreck it.
you can also really slam the throttle coming out of the corners without worrying about the back tire coming loose. ive not ridden the 848, so i don't know if the torque of the bike will make it more squirrely at full lean...
and that top end rush of the 750 is hard to beat...7K..8K..9K..WHAM!!!!
how does the old saying go? if you aren't wrecking every now and then, you aren't trying hard enough. i think that pretty much sums it up. can you afford to wreck the ducati?
jap bikes are appliances. italian bikes are collectors items.
