I installed a YZ426 clarke tank and an SDG tall seat on my WR400. I can't believe how much lower this seat is over my old WR400 tall seat with WR tank. The old seat was flat, you can obviously see the slop on this seat. The seat is so low now it's completely uncomfortable. So much for having a longer seat. Has anyone else noticed a huge seat reduction when switching over to the YZ426 seat and tank?
