I just bought a Zip Ty racing linkage for my 01 426 and I have to brag. It makes my bike handle so much better. It has made my bike so stable when it used to be so hard to controle. I ride both desert and mx and I can't say enough about it I think Yamaha should have produced there bikes with it. I talked to Ty Davis him self when I called to order it. I thought anyone on a blue bike should be using it.
