I've been searching and am having trouble finding an answer to this. If I am looking for frame sliders, fork sliders, etc., would products made for the 821 fit the 939? I'm assuming they would because I don't think they changed the body much but I want to double check before I purchase anything. It seems like I could get better deals by picking up what's marketed for the 821. Ideally I want rear axle sliders (the ones that double as a spool for jacking would be dope), frame sliders, fork sliders, a skid plate or similar engine guard, a radiator guard, and a fender eliminator. My goal is to have these parts ready before I even get the bike so that I can make getting used to it as little tense as possible. Any information will help me narrow down my choices. Thanks all.
