It seems to me the reason for a leading link front end is to reduce trail. And, the reason the shocks are behind the axle is to keep them in a straight line for maximum damping and travel.

Seems to me if the axle ends up in a "straight line" with the original triple trees it's the same as running telescopic forks. You've got to move the axle forward to reduce trail, while keeping the shock on a straight plane.

So, it seems to me you should place the axle where you feel it would sufficiently reduce (or eliminate) trail for the best or most comfortable steering, and that you would place the shock mounts so the shocks do stay in a straight line with the triple trees. Where ever those 2 mounts end up being would yield the best functional result......regardless to how it would look...

Hi Dave,

It looks like the shocks are at the same angle of the triple trees (close anyway), only the plane of the shocks has been moved ahead an inch or two by the upper shock mounts. That plane is from the upper shock mounts to the axle.

So if you drew a line through the steering stem to the ground and then dropped a plumb line through the axle the trail has been reduced the amount that the plane of shocks to axle has been made proud of the plane of the triple trees. The two planes are parallel. (Does that make any sense?)

Doesn't that do what you're talking about?

In short, yes!!!!

As long as the axle is sufficiently moved forward to reach the desired amount of trail reduction, and the shocks can achieve maximum travel (damping) - that should be perfect.

That's a solid approach to the issue.

Nice bike by the way.

That's not my bike, that Nitro's friend's bike. It is way cool though.

I've been researching LLs for awhile now. there's some pretty ingenius stuff on the road.
I might try my own build if I can improve my welding enough.

That's me too.

I can weld and would like a set for my bike, but I have no faith in my welding abilities....

Some day.....

I found these guys on the net. Probably there are many more companies like this.

http://www.scrprecision.com/Default.aspx

I'm going to start some measuring and draw something up (in my spare time-ha!) and get some quotes on components, just for the helluvit.
If all the pieces/parts are bent, drilled, cut, and ready to go, even if I had to pay a welder for half a day I bet I could assemble a set for less than half what a Unit set would cost.

Yes, probably doesn't show well in the pics but he's got just over 2 inches of trail.

Thanks for your thoughts anyway, always appriciated !

Hi Nitro,

Do you think your friend would let you post photos of his build?

He told me he didn't mind me posting his pics. I told him about advrider.com but he said he didn't want to register on another forum, to protect himself from spending even more time on his laptop

Don't know whether you can see the pics through this link:

http://www.motor-forum.nl/forum/list...idebike-1.html

or whether you can only see them after registering there ?

I could upload all his pics in one of my albums but then I'd have to start a topic on someone elses bikebuild including translating everything

If you have a good think about these thoughts, you'll realise that this is not so. Just look at the placement of most rear shocks both mono and twin. You will see that they are in any number of positions from verticle to horizontal. Therefore you can be equaly versatile on the front.

The shock position is determined by design. Traditionaly the shocks are placed in line with the stantion one either side of the wheel. This is simply because it is the easiest and cheepest place, both from a design and function point of view.

There are many other configurations that could be used if the designer has free range with both manufacture time and purchasers wallet. The only fixed perameters are the position of the head stock and where the front axel needs to be. Everything else is down to imagination.

if you go to the Mobec international website

http://www.mobec-international.com/t...51a9ff410cbc37

you'll see that they have LL setups using on or two shocks, including one that uses a single shock centrally located behind the wheel. I don't know if these only work on BMW telelevers, but as val.h says, it seems you have lots of choices on how to build the LL

Thanks for that link, I emailed them for info, I'll post the reply.

No Joy!

Here is the reply form Mobec:

Hello Bob,

we are glad that you found our website.

We are sorry but we only can adapt our leading link systems
here in our workshop in Uhingen.
We cannot ship this leading link fork, because it is all
individual for each sidecar.

Best regards
Elisabeth Beck

Mobec GmbH

Sounds like a great reason to ship your rig to germany, get the mods done, ride around for a few days to make sure everything works right, and then ship everything back home.

Maybe you can schedule it during Octoberfest.

It's only time and money.

A leading link for a V Strom we did. Floating calipers work very nice especially on a dual sport and/or loose surfaces.

Ok I want's it. Now how much to post code 6151. Yep 4 digit code down under. Oh and with some flash looking certification papers to impress the powers that be. Sigh!
Cheers, Bruce
