Maybe it's just me, but what happens when it rains? Looks like that area witll hold water. That can't be good for the seat...
something I hadn't thought of. I'll keep an eye on this.
there does appear to be a doubling up of upholstery material, and i am sure the seat is waterproof. but i definitely won't let water sit in there if it DOES get rained on.
should have a nice ball-cooling effect during hot summer rain

hopefully it doesn't fill up with sweat.
now that you mention it, should be a nice overflow area for all those times i shit myself from almost crashing.
