I was not sure if everyone knew about this or not. It will not fall int the category of rocket science ot anything, but... I was working in my garage last night. I noticed my sons YZF 400 had a rather nasty looking seat. The cover was ripped in many places and it looked bad. I searched through my collention. The only cover I had was for a 1996 Yamaha YZ 250. The two stroke . I figured I had nothing to lose, so I tried it. To my surprise it fit like it was made for the bike. I had to trim away more material after it was on, especially at the back, but th ecover looks excellent. The solid color covers are probably a better bet for this as you do end up cutting away a lot of material on the back of the seat. Something with graphics on the back would look very good as you would cut most of the graphic away.
