    Dpro 140 and 160 swingarm bearings the same?

    Just as the title says, both our swingarm bearings are a bit tight. Have taken mine off (the 160) and will first try soaking them for a bit and cleaning them out, if that fails will be buying some more. May as well pick up both sets at the same time if they are the same size
