Hey dude i had a cbr600 that i got it from a dear friend in lhr. i have done some long distance on it . i am from lhr had a chance to ride it to multan islo muree and all the way to khanispur. its really a good stable bike.
duty and all that u have to chk with the custom office
one advice i will give u is not to deal with the delears they do rip u off in no time they can sell their mom's for cpl of hundred rupees.
its not that hard to get a bike and ship it .
i always prefer to buy a new bike rather than used fucked up that u dont know abt it and all the delears say its in mint condi and all .
other than that remember always spend more money on protection than any thing safty is very imp.
thank u and hope u find the right ride.
