I first just wanted a tall seat for my 05 wr450. SDG
says there 03 to 04 seat will work...I tryed that, had a 1 1/2" gap under the front edge of the seat. The angle of the 05 tank is very different. They also said most likly they would not be making a 05 seat because of cost to sales. I bought a 03-05 Clarke 2.8 gal tank, and ordered another 03-04 SDG
seat. Well the tank fit perfect, the only thing you have to do it turn the rubber gromets around. The thickest part to the outside, and install the alum bushing to the inside (stock). The seat is not perfect, it seams a little short on the front edge, and a very small gap between the tank and the front of the seat. Over all not bad, and can live with. The seat is about 1 1/4" taller than stock. Great for taller riders, and the stock rad. shrouds work. The stock seat will also work, it just bows the front edge up a bit..If anyone would like a pic, send me a pm with email address...
