Melvin
I've had my 1150GS seats melvinned too, and am very satisfied with the result.
I had the BMW low seat which was too low and cramped my legs. The standard seat was fine when riding, but a bit too high when 'paddling'.
Melvin fitted a 3/8" gel insert into the low seat, to raise it a little and scalloped a small amount of foam from the sides to maintain easier paddling. The front and rear seats have both been recovered in 'basket weave' material.
It's easy to tell that the front seat has the gel insert, by it's 'gel' feel when compared to the pillion seat!
