I just Emailed a couple of Ducati dealers to see what they would charge me for some engine modifications. I was thinking of turning my 620cc Multistrada into a 750 and lo' and behold Ducati makes a "kit" to do just that! It would be legal to race in the 600cc class as a 750 because it's an aircooled V-Twin. I'm really excited thinking about doing this modification. Has anyone else ever done a project like this? Take care and ride safe.
