Awe... Wazzamatter Arne, Here's a pic of a very rough draft. Thought about extrusion in the perpendicular direction to cut down on waste, but there may be a trade off on mill set up for the large holes and then changing set-up for mount bolts. One piece design, you'll have to remove the forks from the T-Clamp to install, perhaps a three piece is more appealing but less strength. The drawing has fictitious dimensions but that particular form weights 3# out of aluminum. We can lighten it by changing form of the bridge and perhaps make the bridge perforated. All of the stress will be in an X through the bridge. Extrude holes where strength doesn't factor and it can be lighter. Oh well. It's public domain now. LaterZ Dash

OK OK I have to chirp in here......having had experiences with Telefix fork braces ($80, not $200) I can tell you right now that unless the distance between hole centers is slightly adjustable then the most likely effect of the brace is that it will ruin the smooth action of the fork sliders moving up and down the fork tubes.....Fork tubes are designed with very loose tolerances so they slide...for optimum action with the least stiction they need to slide parallel to each other...the best way to accomplish this is to roll them on a flat surface like a heavy glass table and determined which way the tubes are arced, if the tubes are arced..then they need to be assembled that way and the fork brace, if used, needs to be installed in a manner that allows the sliders to slide without stiction....unlikely with the design shown. Just my experience with braces...I have taken them off and sold them a couple of times, and the handling has improved. Love them wheels, though...and the frame paint job is pretty nice too! __________________________________________________ Do You Yahoo!? Yahoo!

A few years ago Beez toyed with the idea of getting his brother to make us a titanium brace for the KLR. Maybe it will still come to fruition. In the meantime Tim has produced a work of art for us... the 'K9' KLR fork brace. Traveling around Utah for two weeks left no time to install it or evaluate it's effectiveness, but after Gino's initial report, I'll bet that it'll cure most of the fork flexing found in sand washes and mud bogs. Hopefully Gino will have time to do a full report for Dual Sport News. Tim has a shot of the prototype on the bike, www.happy-trails.com Attached are shots of the production model. Redondo Ron

That dry heat in Moab must have dehydrated you Ron. The correct URL is http://www.happy-trail.com - not trail"s". BTW, the K9 weighs in at 1.6 lbs. John T. Oldepus - batting cleanup...again

Redondo Ron  Looks beautiful, but like Bill was mentioning... How does it account for the slight variances in the distances between the fork tubes?  The attachment points look "fixed" as opposed to adjustable.  I realize this distance variable will be minute - and maybe not enough to make a difference - but in theory, any side-ways pressure would cause stiction would it not?   Having said that... it is a work of art and if it works as designed that's awesome.   Arne

Tim's money back guarantee and Gino's initial input is enough to make it worth a try. But I love to fan the theory volleys. Here it is on the klr after a week's worth of Moab trails. Redondo Ron

Thanks Mr. Goat, I don't have any experience with fork Braces so I didn't know. That is very good to know though, and perhaps I'll think about that some more. Again this was rough and I was just getting thoughts out there for some feedback. I'll never take something like this to production, too much capital - not enough return. But I might throw up something on my mill and have something for myself. No not that design, that's an awfully large billet. How do you go about mounting the, say Telefix brace? My guess was that it was made so that you didn't have to remove the fork tubes. Do you compress the forks and measure then release and measure along the travel? At what point in the travel do you tighten up those cap bolts? Thanks. LaterZ Dash At 04:35 PM 6/14/2000 -0700, bill e goat wrote:

I installed a Telefix on my EX 500 a few years back, Major improvement, Well worth the 60.00 bucks, But not worth 200.00 I would like to put a set of KX 500 forks and triples on, Mike In a message dated 6/15/00 8:30:29 AM EST, dweeks@... writes: << How do you go about mounting the, say Telefix brace? >>

The Telefix, which seems popular for whatever reason, has elongated holes where the shank of the screws allow some adjustment when mounting.  The instructions that come with the Telefix brace specify that just clamping the brace on without checking the action of the forks will cause the forks to stick, they recommend that you do a gradual tightening of the clamps as you work the forks up and down to align the two pieces (there is a front and a rea piece).   In experience, I have found that the most important motorcycle part to contribute to fork strength and rigidity on the road is the axle and pinch bolt arrangement at the bottom of the slider.  A large axle helps, as does a double set of pinch bolts, neither or which the KLR has.  If you look at a modern sport bike you'll see what I mean....a large, maybe 25 mm axle, with big strong pinch bolts, two to a side.   Bill Goat, at home, cleaning up the weeds.
