This Performance linkage Lowers the rear of your 2010 RMZ250/450 7mm.  We have found great results with this linkage mostly noticable in the turns with riders finding it a lot easier to 'rail' long berms and exit faster onto the straights.  Whilst it surely improves high speed stability all test riders found this mod very noticable in the corners.  We tested many different linkage arm lengths, with 7mm being the clear winner over standard length.

Also suitable for riders that like the rear end low feel without having to wind off the shock spring pre load.
