I dont sit on my dirtbike seat either. I ride all singletrack. The lower the better lol. Your seat looks like it might be built well but its too tall, too open for a rear mount and looks just plain ugly. Thats my opinion of course.
The after seats dont hold up like the stock seat overall. I have a MM on my Apex but it is a brick and doesnt hold up, it turns white after 2 rides and pills like crazy. All they have to do is get rid of the Cordura type matetial and it would be better. Boss is junk as well, zippers break constantly and they dont give a chit, it attaches to the sled with snaps which is pure garbage, although the foam is the best.
They all suck. Friends of mine run the stocker Nytro and it looks new, holds up well, right height, and looks good. Some will disagree but why spend 700 bucks for junk. Weight ?
