Agreed and I want to add somthng too. There is no standard term " Heavy Bike " is any category of bikes there such as Sports Bike, Touring Bike, Choppers etc. In pakistan Heavy bike is the name given to every sports utility and Naked bikes ( sports bike without ferrings ) same as every chopper looking bike is called harley davidson, without knowing that if it might be a TRIUMPH. So in my opinion heavy bike is a term used to define any bike which has looks and sound other than the local bike in Pakistan.
