So there was no other damage on the Left side - Scuffed or dirt packed footpeg, scuffed or dirty bar end, Dirt packed into the tire tred? I ask because for a bike to slide it would have to have at least 2 points of contact - it's not going to slid on just the slider only. But it sounds to me the slider did exactly what it was designed to do take the brunt of the impact and destroy itself instead of more expensive parts on your bike.
I've had more than one crash that were very similar to what your describing, minimal damage except to the slider/slider base on the initial impact side, but then something catches, flips the bike and lots of damage occurs on the other side. In fact I the first time it happened I was SURE the slider was the major culprit - until I saw the series of photographs of the crash a couple weeks later. The slider had actually dug in 3 times before the bike flipped, and the only reason it flipped was because bar dug in and pole vaulted it - but there was only a little scuffing and some dirt on the bar... no real indication that that was the real cause.
I've also used built and used my own "under the body" sliders in the past and the results weren't any different - in fact it I had to estimate it they usually did more cosmetic damage to bike than the traditional through the bodywork sliders.
After that I really started to think about it and applied some basic physics & geometry to it. The first thing the really "clicked" for me was when I look at the slider placement - it's very centrally located on the bike, this means it's virtually impossible for the slider, by itself, to flip a bike. A little experiment that illustrates this is take a 5x8 note card or something similar poke a pen or pencil tip so it just barely sticks out. Now run it along something and hit something that will catch it and stop it - what happens. Now poke two more holes through it replicating the locations of the foot peg and bars (because those are the three things that "stick out" from the side of the bike - even the stock folding pegs still stick out when folded) and try each individually - the only one that will actually cause a flip will be the bar - because it is high and close to an edge (making it furthest from the center of gravity of the three) giving it the largest MOI (Moment Of Inertia). Now when you start adding in tires... by far the most common thing to catch and cause a flip - and typically leave little or no evidence...
This brings me back to: If a bike is going to flip - it's going to flip, with or without sliders, doesn't matter if they stick through the body, or hide under it. AND it's going to SUCK when it does flip...
Definitely makes for a good discussion :congrats:
