I bought a set for my 07 WR and noticed a big difference on it. This 04 was a little more of a challenge to get them on since it had triple trees for 45MM forks, but I can only imagine what the difference over the stockers will be. There were a few AOSS boingers out there for reasonable also, but everything I've seen says to stick with the SSS years.Let me know when you mount those. I can get some same year off a 250f. I am going to buy them anyway but won't try them until the spring
