Have had time to look at the thingy, and here are my comments:
--------------
Xenonian83rd
any SP sidearm up to Common availability
The Stub Revolver is the only weapon that actually qualifies for this.
Instead, maybe change "Lasgun OR Combat Shotgun" to 'Combat Shotgun or (laspistol and sword)' or 'Combat Shotgun or (auto pistol and truncheon)'?
1 Tauros AV per player character, [...]
Special: two player characters may exchange their individual vehicles for a single Tauros Advector (including an NPC driver)
Is the 'Tauros AV' supposed to be a Xenonian Combat Bike instead? and two characters can switch to a Tauros Advector instead? Or is the 'Tauros AV' some other vehicle?
And why wouldn't two people want to pool up into something with much more resilience and a free pintle mount weapon?

Xenonian 88th
any SP sidearm up to Common availability
Same deal.
Would assume it takes one hand to use the bike, so maybe replace sidearm with spear, so you can be motorcycle cavalry? Would assume there are rules for spear/lance charges in the cavalry section.
Is each comrade supposed to get their own bike as well? If so, may be worth a clarifying sentence.
------------------
Xenonian Combat Bike
The Sentinel and Hellhound both have +10 manoeuvrability. Is your intention to make a bike with a side car less manoeuvrable than them?
Maybe give bikes +15 and have sidecar reduce by 5? So a bike is more manoeuvrable, and bike with sidecar is as manoeuvrable.

Xenonian Primer
Where does the fuel come from?
Is the world supposed to be rich in Promethium, so you can just pump it our of the ground and run your bikes?
Do the vehicles mostly run on alcohol, and there is some common sugar heavy plant that people distil fuel from?
Are the vehicles mostly electrically driven, so you can run them on lasgun powercells, which you can recharge easily with whatever (wind, water, people) powered thing you can scrape together?
Or something even more esoteric:
Example: there is a webway portal on the world that the dark eldar use. Most of the bike engines literally run on pain and suffering. And the shadowy dark eldar mostly view the world as a very large reality TV show, where they make sure no side gets a lasting advantage over the others so that the screams can just keep going forever, or, at least, until the get bored. This gets you the bonus of raiders bleeding captives out into the fuel tanks of their bikes...
