Anyone used a Marsee Corona Tank Bag
 

Rex Marsee Designs, Inc.

I like the look of them and think it would be ideal, but i have an Aprilia which they dont list, i have been waiting for a response for weeks now. My shiver has a plastic tank, but i like the look of the corona system.
My aprilia fuel tank filler has a 6 bolt 78mm PCD bolt pattern, please could anyone measure their bikes and let me know the fuel tank pitch pattern and PCD

Many thanks

Ian
