Rallies – they sure do (have fixed gear with trailing arm). Had to look for a picture.

Cirrus. Negative. The actual legs holding the wheels (fixed gear) are inaffect a piece of spring steel (cart spring). Very simple and light weight.
Sure don’t think any fixed gear with the weight / luxuary of trailing arm.
Rallyes ?
yes,a Ceriani 230 mm, it is in the BMW since 1980 – a while after I had a very hairy moment when coming round along a sweeping bend in hilly country at 160 kph and seeing a crowd of cattle on the road . I was 21 at the incident and in the army 15 months duty . . .
The leading link in the 1965 R 69 S stays level under hard braking, anti dive .
FWIW: if there is some play in the links they may create some toe in or toe out when pushed backwards…
Vic, nice front brake. I’m guessing it’s a Ceriani or Oldani?
BTW, leading link suspension can be to set to rise or fall under braking depending on details of the geometry.
Sure zero toe on aircraft mains. When on the wheels they only go in a straight line at speed – one hopes
That ‘shaft drive’ BMW bike looks superb.
Do nosewheel aircraft have toe-in or toe-out of the main gear? That would affect which direction is easiest to push.
The club I learned to fly with had a Beech Musketeer (trailing link). I don’t recall it being any more difficult to push back than any other similar weight aircraft.
The lightest trailing link main gear aircraft I can think of is the Ercoupe.
While the jacking effect when pushing backwards may be real, I’m not sure it’s a substantial factor. A lot of motorcycles have been built with leading link front wheel suspension.
