i would agree on the tail mount superbike tail or not. i think you have to use wellnuts (is that the right term) so that the bodywork isn't the only thing having pressure from the bolt when mounted to the frame. I don't have a superbike tail (have one on the gixxer, still super strong thru 3 crashes, though all lowsides). what i just didn't like is there was a fair amount of surface cracking or a layer of the fiberglass that occurred. but it still withstood a lowside at T1 Infineon. it's just that compared to my sharkskins, the sharkskinz were a little more flexible but the paint prep on the attack was pretty good.
if the 848 clipons are same as 1098, i just realized the stockers are a pita to replace the bars on. I have spare vortex bars that are just uber tight to slide into the stock clipons. even removing the plastic cap, i had to use a rubber mallet to insert it. worse, the inside of the two bolts require a notch on the bar to let it thru. stock bars have that notch in them. so you have to file a notch thru. you'll see what i mean once you remove the bars, not to mention working with the pins to hold the clutch-side switch and the clutch MC.
the above is just some non-racer friendly items on the bike that makes crashed parts replacement process a pita. i just ordered some vortex just to get out of prepping bars with notches on them.
i'd get the front axle sliders (don't get r&g as it's a pita to use the under the fork stand) and the swingarm sliders. my r&g protected the swingarm but there's no replacement parts for the derlin. so i switched to speedymoto swingarm sliders and they look beefier actually.
don't bother with acculign rearsets. the eccentric will not hold on a crash. i know so from my lowside and looking closely at the design why the collet and peg were missing after my crash. they're nice, but just can't hold up in a crash. i;m going back to my trusty vortex.
