Rumbux are well worth the trouble. I totaled my 2013 recently in a deer versus bike accident and the bike flipped and rolled. The Rumbux survived very well and neither side-wing bent enough to touch the plastic side panels. The skid plate hit a culvert and bent upward pretty good but the sump suffered no harm and the oil stayed inside the engine. I was amazed that the bike was still ridable (not by me though-I was beat up badly), however insurance totaled my Tenere. I have a new set on order for my new 2015 Tenere.
Quality stuff. Looks good. Holds up to excessive abuse. Priced right. Easy to change the oil.
BTW - the Caribous did well also. One stayed on, the other broke the lock as designed (which is replaceable) and flew off the bike. The case was reusable, although rashed pretty bad. Racks were a little tweaked but easily fixable.
