Good day, i want to ask the owners of super bikes that which is the most suitable 400 or 600 cc bike tu buy in Pakistan? I live in islamabad.. I like gsxr600 or honda cbr400rr.. i heard that kawasaki and yamaha get heated up.. i want to know who's mileage is better? whose spare parts are cheaper and easily available? which bike is more dureable? how much will it cost for regular mantainance in islamabad? where are some good motor mechanics available in islamabad? what about non custom bikes? i love bikes, but its my first time getting a sports bike.. what about custom bikes that are built from scratch? there are some modifiers who purchase old models, put all new engine, fairings, modify it to new shape and just make it brand new.. what about them? Should i consult them? My options so far are gsxr600,cbr400 rr or kawasaki zx6r..i need all the information that any biker brother got
