I have a 2003 yz450f...A couple years ago had the suspension revalved and resprung for my weight. Due to life circumstances..I have been to the Little Sahara dunes two weekends, and went to ride the desert outside New Mexico two weekends, and have been to the local mx track two seperate days. I am not a big jumper at the dunes and I am not a fast guy on the track. My fork seals were leaking and I took it into the local shop to be fixed and they told me my fork bushings were worn and needed replaced. My question is: Is the sand that hard on forks? Is there something else going on to wear the bushings out so fast? Thanks for the info!
