Singh, This may be a crazy idea, and I've never heard it used on a Bike before......But, what about using some Cathodic protection to prevent rust?....Installing an Anode on the frame may prevent rust. I would think it would only work while the kick or center stand were down, creating a contact with ground?...They are used on things like Out board motors, Water Heaters, Buried steel pipe, and etc. Might be something interesting to look into?
