My wife and I are getting our XT600e's made up for some serious traveling. Her bike is stock standard and low milage, whereas mine has been used to commute, travel, green lane etc. Mine had an aftermarket silencer on it, but my wifes didnt. My swingarm shaft and bearings showed wear to the right hand side, hers did not. All my bearings are changed now and all linkages greaced. I have a Marvin pipe on it now. Here's the thing though, when my suspension in compressed it kinda goes downwards slightliy diagonally, in a way which could wear the bearings out on the right hand side. My wifes bike doesnt, hers goes straight down and up.
Why? Both bikes have new suspension and all bearings, so why the difference? Is the exhaust on the 4PT part of the subframe bracing? Even a little? I know in older models it was an integral part of it.
