Rank the Big Four

[Jared]

Having owned and ridden all but Yamahas (I did ride an fzr a few times)...

It's all 100% subjective... Like Srinath said....what kind of bike -what year range.....

Big Musclebikes......Kawasaki all the way.....for Me.....
I ride a ZX11 (Yeah yeah  Haybusa this Hayabusa that....The ZX11 was the king for 10 years before the Busa showed up..and my ZX11 is still prettier).

My first bike was an 89 Gs500e...  and I'm still tinkering with them...So go figure.
I had a CBR 600 F2.....LOVED that bike...tho the fixed seat with removable tail pieces was a pain...the rest of the bike was a dream...

Never owned a Yamaha....but it's all good.

By the way Suzuki and Kawasaki have an alliance....They are still seperate entities that share parts sourcing ,R&D and  blah blah blah...read:

Yes some models will be the same ( Like many Car companies have done with other companies...yet retained most of their own lineups..).

Do a search if you're bored  (I seem to have insomnia  again lately...so I'm up at 3 am..)....

Anyway

I'd have to say Honda is at the top overall.....
Juggle the other three around anywhich way.... but what does it matter- ride what you like.
