I'm looking for comments/info on tall/soft seat foam for the WR450. I rode a 426 with the Factory Effex tall/soft seat and fell in love. Unfortunately, Factory Effex doesn't make a tall/soft for the WR450, only a tall/stock (whatever that is.) Let's face it, the WR450 stocker is like sitting on a brick. So, who makes tall/soft seat foam for the WR450's?
