Harley-Davidson motorcycles can be equipped with cast aluminum wheels, forged aluminum wheels, or the traditional wire wheels. Cast wheels are usually thicker and heavier but not stronger than forged wheels, which are made from solid piece of metal. Spoke wheels look great on a Harley but they need maintenance because the spokes loosen with time and need occasional tightening. Spoke wheels are usually used with tire tubes. Remember that the wider the wheel, the harder it is to control your Harley.
