If not, guesses would be appreciated.
That said, I could see an argument for any of the above, being Medium, Large, or 1x2, although the latter obviously has the aforementioned "annoying rules questions."
I mean, does a character on a 1x2 vehicle now threaten 10 squares instead of 8? After all, that doesn't make a lick of sense. (Yes I know how the mounted combat rules work, shush.)
Porkers ride motorcycles that are 1x1.
Yup:
1) regular motorcycles are 1x1
2) Skycycles (double seaters) are 2x1
fwiw: I've rebased these, these and these (both wheels) onto 1" bases and they worked great.
I use these for skycycles (even though they actually have a 2x2 footprint)
also, 2 people can ride on a normal motorcycle. It never clearly defines the size of motorcycles except for the skycycle omega tech card.
honestly i don see why the rules for threat squares would have to change.
I believe because most people are thinking of the regular mounted combat rules.
the motorcycle is taking up the space, its not your body.

Good point: a motorcycle could effectively just be kinda like a piece of furniture that moves with it's rider... no effect on occupied squares. I believe the D&D vehicle rules (rather than the mounted combat rules) actually do work this way.

It's implied for the mounted porkers, since the scenario (FiFG p.124) shows them as occupying only 1 square, and makes no mention of the motorcycles affecting other squares. Mechanically, those motorcyles have no effect outside the porker's occupied space... but I guess the bikes could still be 10' long choppers, and just not have an effect, kinda like a 10' pole being carried by a PC.
The Hog Boss had the OCC Splitback Cycle (and I put a Gamorrean Guard on it). It took up 3x1 squares.
The Porker had an ATV. That was 2x2.
The Canned Hams had a variety of vehicles... a Ducati (2x1), a Canyon Carver (2x1), and a Go Kart (2x1).
fwiw: I've rebased these, these and these (both wheels) onto 1" bases and they worked great.
I couldn't think of any miniatures with cycles, but those are pretty good ideas.
Looking at some stuff on the typical length of motorcycles, 1x1 definitely works for some smaller sport-bikes (like the Ducati), that are just about 5' long. Some bigger bikes, like that OCC Splitback, could be 2x1, though, since they can be upwards of 9 feet long!
I'm tempted to have them be 2x1 standard, though, since you can have two people on a bike. It would make for some interesting "flanking" angles, but that's fine.
If you're going with the idea that motorcycles are larger than 1x1, then you should make them 2x2.
1x2 / 2x1 or any "non-square" configuration for less-than-gigantic creatures/vehicles is pretty much a bad idea in 4e-based games including D&D.
fwiw, Adventurer's Vault p.14 says:
"Space: Unlike creatures, which can move around within a space and squeeze into smaller spaces, vehicles occupy all the space within its dimensions. As a result, vehicles cannot squeeze. For example, a wagon takes up a full 2 squares by 3 squares, meaning it can’t fit through a narrow chasm that is only 1 square wide"
