For your interest my standard seat at widest rider position before seam was 3-3/4" top curve of seat to seat bottom and the new 4" more spares company seat was 4-1/2" .In deference to Angelas comfort and my short legs I have taken it to my upholsterer who will reduce the rider position to 3-3/4 but maintain the pillions height I suppose it will be a bit velocette touring like. when complete I will post photos.
PS. I wonder if that constitutes "substantial modification" to the DVLA?
