They were both introduced in the mid-70s, so almost 40 years!

The stock stabilizers on all Harleys actually move in a slight arc, as does the True-Track and all its cheap copies. However the motion involved is so small that it approximates to a straight line, for all of them. The suspect copies are those that use a very short link, which indicates their 'designers' don't understand what they are messing with!

Yes, the short links arcing more ... and at one corner instead of the middle.

Something I would not mind seeing on a Harley fork is anti-dive tied to the brakes. Honda has played with this off and on, and I've found it to work very nicely on the bigger heavier touring like bikes. Wouldn't do anything for wobble, but would help with control under hard braking.

True-Track confirmed that the rear cage only will fit but not the frame attachments, so the later ones marked '09 might be consider the later development. YMMV.

Shorter bolts, more circumferential pressure being better?

The reduced amount of air available stiffens the front suspension while braking, reducing dive. Better damping achieves a similar affect, bearing in mind the fork damping on most Harleys is mediocre.

Forks are in pieces right now, plan is to put single rate springs and intimidators in them, ditch the air (but keep all the parts, just in case...). That reminds me, gotta make some calls and make sure I can get those parts to fit the old Glide.
