Replacing my 996s as my designated track bike and WOW, am I having fun on this thing. Such a sweet machine. Really performs better than my skill level.
I'm sure your mods help, but they really are light years apart.The 996 has motor work and lots of track goodies. But it doesn't have the electronics or 20 years of innovations.
They weigh almost the same, but the 959 handles like it's on rails in comparison. It "feels" lighter.
