Thanks for the tip, I'm not sure if the 1200RT has the same coil but I know all the 1150 2 spark engines are the same as the 1100S 2 spark model, so I will defiantly ask the question, and your probably right about the extra suppresion for radio, but as long as it fits and makes a spark I'll be smiling. And as for the battery, well I'll just have to ride it every day!
