    rear shock size on a 2010 Mach4

    Looking at a used 2010.5 mach 4, but it needs a rear shock. Anyone know the Eye to Eye and stroke i need? i know in 2011 they changed the stroke to 1.75".

    thanks

    Pretty sure it's the 7.875 x 2.25 (200x57) sizing, or at least I think I had a 57mm stroke on my '10 Mach 4.

    Haven't had it in a while though, so will have to check and see if I've got my old setup docs for that bike.

    Edit scratch that... Just looked at my old settings, and I've got 15mm for 30% sag, which must mean I had a 50/51mm stroked shock. Not sure on the I2I then now...

    7.5 x 2.0 shock size unless it is XS size frame. You may wish to have the shock tuned if buying aftermarket. Aftermarket Fox shocks come preset and may have too much compression and rebound to work well with the PM4.

    This chart is helpful for determining shock sizes:
