We had our Honda Aero cleaned at a charity event a year ago and the dealer used this on it. It came up sparkly and it took off most the coffee stain that was cooked onto the hot muffler but not quite. Then I bought a bottle and cleaned it again when the muffler was cold. It took the rest of the muck off easily. How about that! The bike looks great and I'm impressed with how well it cleaned every material; chrome, metal, tires, seat, etc. Gave my roommate some and he did his Ninja with it and commented how good it looks. This will be my go-to cleaner for bikes.
