Well lets see if it will help you to decide

KAWASAKI NINJA ZX6R 2007 -Vs- HONDA REPSOL 2010

1-Engine Displacement= Kawasaki =599cc & Honda =800cc
2-Weight = Kawasaki =180kg & Honda =150kg
3-Horse Power = Kawasaki =101.6hp & Honda =208hp

Well i think if u like speed then go for Honda but if u like safety more then speed then go for Kawasaki.
Good luck..
