This IS kinda cool. However for off road it is probably better to have th ecaliper up on top. Just food for thought.Many of the trike folks use the plate as shown on the downtube in lieu of bending the fork tubes. We use double wall tubing for the fork tubes which are bent to whatever angle we feel is best for the application. Lots of ways to make aleading link happen no doubt. Floating calipers are the way to go though.

.......what do you guys use for the joint at end of the fork legs (where the lower swing arm attaches? I have seen some bikes use ball (heim) joints, but was wondering what most are using. Bearings,bushings, or maybe just steel on steel. Any help...pictures would be awesome! Thanks!

Most common used are rubber bushes. The same kind as used in the A-arms of cars.

You don't! You use an interference fit to press them in, just like IMZ has done for decades.

On the front end I built back in 1992/93 I used the Heim joints, 3/4 inch with grease fittings. That front end has over 100,000 miles on it and I did replace them once.

I do like the rubber car bushings idea, have to keep that in mind if I decide to build another front end for the XS400 project

You can buy high performance Polymer bushings instead of the standard rubber ones.They will have less play/flex in them.

Do the polymer bushes also have enough flex in them? The rubber bushes are also the hinge. They must be able to rotate about 15 degrees.

We have used both and I prefer the heim ends. The ones we use are aircraft quality 3/4" x 3/4". No grease fittings. Weldnuts are wleded into the end of the fork tubes To receive these. You can play with camber on the front wheel a little using these by screwing them in and out.

Mine's ready, EHE design ( Netherlands ) built it. I liked the design of the leading link fork on his Hacked Wing so much I asked him to build me one.
It's for my BMW R90/6

Talking Sidecar front end design

Just going back to the basics.
We want to reduce the trail or caster effect of the front wheel don't we ?
First of all what trail are we aiming for ?
1. Well what about remake the triple trees with a different fork angle to bring the wheel further forward ?
2. On the leading link design do we want to get the main bent down tube vertical at the lower section and have the swing arm in the horizontal position ?
3. Brakes. Floating or attached to the swing arm ?
4. Main tube thickness 5 or 6 mm ?
If I can't find the right tube diameter how about sleeving it to suit the triple tree ? ie 46 mm triple tree and using tube of 40 mm by 5 mm wall thickness and turning a sleeve of 6 mm and plug welding.
Does this sound logical and safe ?
Thanks for your input
