Any crash you walk away from is a good crash so that is a win.
The bike is an insurance write off. The rear frame is bent and that will mean it is totaled by the insurance company so accept that and move on. Remove any accessories you want to keep prior to the insurance company seeing the bike as when they do whatever is on the bike when they write it off becomes theirs.

I've owned there Tiger 800's, Gens 1-3.  The Gen 3 XCA is the real deal, it lacks nothing (rather annoying gear whine from the straight cut on the imput shaft after they removed the backlash gears) aside.
Smooth engine which is perfect for motorway cruising, great off road, and bullet proof.  Loads of cool ad ons and good value.  I picked up a brand new one in 2020 for £9999 with panniers.
I tried the 900 but found the vibes really annoying at around 75-80mph, same with the new 1200.
Trouble is, if you have come from the old triple engines the t-plane just misses the spot.  That's because they aren't the Triumph Triple.  They're a hybrid that's not sure what it is. 
The reason why I buy Triumph bikes is because of the engine, simple as that.
I've ridden and owned most of the other makes but found the triple to be just what I wanted.
Now they've decided to get ride of the reason you buy a Triumph to replace it with, er, a bit of this and a bit of that?!
I wanted to upgrade to a bigger bike as I intend to do more touring and although the 800 is great, it's a bit manic over long periods but because it's smooth, it's doable.
Now I'm getting older I want a bit more finesse.
The Gen 3 Explorer is perfect but a bit of a lump.
The new 900 and 1200 would be great with the 180 degree Triple but they don't make them.
You either stick with your 800 or change brand, none of that seems a great move by Triumph.

I've lost count of the number of times I've been heading towards the M40 from Northampton and had some muppet decide to go straight on in the very clearly marked left only lane at the roundabout on the BRackley by pass. The right lane is left or straight on, or if you are a motorcyclist it's the short cut to an early exit.

The AliExpress beaks are completely plastic. I haven’t looked at an OEM one but I think they are the same, although I obviously can’t directly compare the quality of the mouldings. At the price, I was willing to take a chance and I think that I got a bargain! There are lots of other Tiger 800 owners who’ve reported on Facebook that they’ve installed these cheapo versions and I haven’t seen any bad reports. If the beak gets a heavy knock it’s likely to crack but maybe the OEM one would be the same (?).

I have changed the horn since installing the beak and access was easy without needing to remove anything else.

I believe she sold the company a few years ago. Been with them for around 14 years.
Changed to Mackenzie Hodgson.
Seem good so far.
Good luck negotiating this annual minefield.
