Mood: Is 112 dB loud enough?? What??
In direct answer to your question, you can get down to 155kg without fuel. As already said, it would cost you a fortune and just about every component would be different. You'd be far better off buying an RS bike. You could always swap engines and sell the RS engine. Probably not what you wanted to hear, tough.
