It's exactly my concerns as well. I love the idea of a V4 as the Tuono engine was pretty epic when I borrowed one a little while back but the low weight of the Panigale is what does it for me, especially the R. The RSV4 is 20kg heavier than the Pani R!
didn't realize it was that big a difference ....even if "it looks it" from the side
..R is truly a great bike...except the Oil Leak Meltdown its been having
