I've got an oem seat with no cover on it. The previous owner of the seat shaved it down, taking off of the top about 30-40% of the foam. He did a somewhat good job except the very back part dips down just a tad, but feels comfortable so I'm not worried. I like the thinner seat because it allows me to sit just a tad lower on the machine and at 6'5" that helps.
There are tons of options for seat covers so just looking for some opinions. I want to go with plain black, no writing. Don't want a gripper or hump. I'd like to go with red but I have oem plastic and most the red seats I see don't look like they match oem plastic correctly.
