depend what bike you have?
if you have 70 or 125. i would use just about any wax. it doesnt really matter because all the place u put wax on is metal.
if u have a sport bike, where all the parts are plastic, use a little expensive one like Lysol wax or Mother's wax. plastics start to fade and have dull look if u use cheap wax..
im not sure if you can find that good wax in pakistan.
