I have seen the yfz shocks on the lt250r, also I am pretty positive banshee shocks are damn near the same length eye to eye. my friend has a shee with elka shocks on it and they are the same eye to eye length of my works on my lt. My brother in law has a honda R, he upgraded arms and i brought his over and fitted them on my lt frme. they  didnt look like it would work from what i remember it was the shock angle on the r is different or something. I have seen guys bolting up z400 arms on an lt250. not positive what mods are needed to make that work. i lucked out and found laeger arms and my other bike has lonestar arms. they are both 92s. Metaltech might make arms for the lt still not sure.
