I'm looking at putting a new leading link on the front of my K100. The current one works but isn't "certified" and doesn't actually give me any trail reduction because the axle is still in the same line with the steering head as the original forks. Any suggestions for a maker? Needs to be legal.
The one I have was made by Lee McPeake Engineering in SA. Seems strong enough, but is a bit crudely made.

SRK Engineering in Bathurst or BME(Bob Martin Engineering) in Vic if they are still doing links. In SA you should approach Highway Sidecars in Mt Gambier, I know they do sidecars, not sure about links.
Or think outside the square and buy from OS eg Unit http://www.hedinghamsidecars.com/Unit-Leading-Link-Forks.php

Hi mate,
There doesn't seem to be a lot of people doing this sort of thing these days, sidecars being the unfashionable things they are.
There is Sean Kelly in Bathurst:

http://www.srkengineering.com.au/sidecars.html

I believe he charges like a wounded bull and take years to get stuff done. We are talking thousand of dollars.

I swapped a few emails once with a bloke called Paul Rooney, who lives on the north coast near Ballina. He builds things and was talking about making a double sided swing arm for K bikes but he never got back to me. You could try contacting him on rooney@northern.net.au and see how you go.

I'd be tempted to modify the one you have to give it more wheelbase...maybe an extension piece or something along those lines? Something to mount the axle further forward...

Whatever you do, don't throw the old one away!

Sean.

my thoughts were the same, maybe a 2" extension of the existing swingarm, dependant on if you can find someone willing to provide engineers specs for the RTA.
Unfortunately a lot of the small home based fabricators are giving up the game due to RTA redtape. bit of a shame.

I thought of just extending the lower arm of the set I have, trouble is to find someone who will do it. I might just ask around and see what happens. I know Sean at SRK is expensive, but I've sent him an email enquiry anyway.

Some how I don't think it would pass muster for the relevant authorities.

It shouldn't cost a million dollars to extend your existing front swingarm a couple of inches. Any steel fabrication/engineering business should be able to do that.

Once you experience the difference it makes you'll say its worth it.

This is a set a forks a designer/consultant called Tony Foale made and designed in the late 70's and were used buy Kawasaki and others for their bikes. I want to make my version of these forks using Scaffolding pole tubes for the legs and use a set of USD fork Yokes to connect both scaff pole fork legs together and fabricate the  leading link arms and find a shock absorber to go inside the scaffolding tube leg. The only problem I see is getting the right size shock to go inside the tube but thats part of the fun of a self build project like mine. I think it will go good on my K100 diesel project bike.
