i agree with biker_isb...the power of a SAKI is great...but their parts arent easily available in pak...is this going to be ur first bike... ???
if yes...then i'd suggest you start with a 250cc class...say a fzr or a cbr 250cc...but if ur used to riding sports bike...
a decent zx-6r should cost you around 250k...but do get it checked with a good mechanic like said before...parts of kawasaki arent easy to find :)...good luck (Y)
