I find myself agreeing with a member of Chaos for once... what is this world coming to? However I think there should also be a catch like a skill to ride bikes of your faction and yet riding another factions bike should have a huge penalty. Any ork or Mon'Keigh that would be foolish enough to jump on a jetbike should be far too slow to react to the reactions it takes an Eldar to control such a bike and the same should be for the others as well orks should have issues with chaos and mon'keigh bikes and eldar should as well as they are so heavy and clunky. You get the idea.
I'm wary of using bikes from other Factions. A LSM would be wary of being corrupted by a chaos or Xenos bike (maybe rightly so with Chaos ones). Just about anyone can use their bikes. Eldar wouldn't want to touch a Chaos Bike. Mon-keigh tech, they usually find abhorrent. I would easily believe that they would have some remote to psychically recall their bikes. Of course between something like this and any attached Soulstones it may be hard for SM or Orks to ride one, and damn near impossible for a CSM. Chaos will happily ride anything (especially if they've been on the Warp Dust), and for some the faster the better. There always a chance that their bikes could be Daemonically possessed, which means they could also be recalled to the rider and have a corrupting influence on a rider from another Faction, maybe even just throw off such a rider. Orks too will ride anything, they do like steal and re-use items. As for their bikes, I think all other Factions could ride them but only at risk to their own lives. The thing is about Ork technology is that they can build just about anything out of just about anything and make it work. So they could build a bike that if anyone but an Ork got on would most likely either fall apart or explode. But when an Ork gets on it will either work, work spectacularly, or explodes spectacularly (sometimes a combination of all three).
Yeah this may be one of those things like weaponry where the lore does not support the action, OR at the very least complicates it to the point that it's excessive work for the Game Design and Animation staff. You sort of end up with a spreadsheet like this, and even then there is a couple of Sub-Factions who would neeeeever indulge xenos gear (Ultrabros riding Orky bikes ? What Magos said about Ork tech reliability ?): CSM: Eldar, Orks, SM Eldar: CSM, Orks, SM Orks: CSM, Eldar, SM SM: CSM, Eldar, Orks Unpossible Unlikely Heresy I know this isn't the place to discuss the whole Ork 'reuse, reduce, recycle' mantra (who knew they were ...green ) but I'd rather Boyz could earn RP from taking out vehicles rather than thieving other player's tools directly. If you kill/cap an enemy's bike then you recover X amount of RP representing the parts, frame, fuel etc recovered from the heist. The more effective the Git the more Flash'ee and frequent his ride. It would probably be a good mechanic for F2Waaagh! players who MAY have XP/RP restrictions but I would also see no harm in letting payed players access the scheme, it is very Orky to salvage.
