If necessary I could kick up the front bend a bit to give a better view to the motoscope..

I have lots of versions in sketches and in ideas, time to get some tubing and make some drafts...

I never was in love with my Tarozzi clip-ons.. i think the clamps look chunky..

[sinister902]

BLAC, what about having two holes in the top triple tree with some attractive hardware hiding mounts underneath the clamp like the hugh's handbuilt XS650 bars? it would give you a similar stance and position to clip-ons but with a more attractive appearance.

[BLAC]

It's been my preference to have the Scope tilted towards the rider some. I've tinkered with a bolt on mounting bracket to the front of the triple, with a 15* tilt for the Scope. That should keep the back of the gauge and its wiring away from the headlight shell.

This all depends upon the length of the headlight ears an how far forward the bucket sits. If the gauge is too flat, it conflicts with the back of the bucket.

As for your bars, if you're going to mount them in that way, why not use custom fork clamps and clip on style of bars? The mid section of the bar is superfluous since it doesn't seem to lend itself for a useful mounting area. Custom clip-on clamps would be the route to take with your approach in my opinion. (See, I'm still after your wallet!)

I have the Cognito retro top triple clamp and Tarozzi clip-ons now.  I want to keep the Cognito clamp, but am fine selling off the clip-ons.  I am with you on the custom clip-on mounts, I just don't know who will manufacture them and at what cost.

I like the continuation of the bars coming to the center because it would contour right over the top of the headlight and would probably be close to the same radius of the motoscope.  I was planning to mill out the center section for the motoscope to be countersunk into the bar so it sits flush (if that makes sense).

That is very cool, I have not seen that before!  I already have the Cognito retro style upper tree so im not sure there is a way to modify it to work like this.. worth thinking about though!

[sinister902]

make a real drawing with real measurements and PM me, maybe I can whip something up for you for a reasonable cost.

All you need todo, drill and tap the triple underneath for 3/8 or 10 mm bolts...hope there is meat back of the edge, so you can blind tap. Then run mounts from under guage so they are hidden.
 Bend your bar as in your drawing..I really like it.
 Then you may have to bend the first few inches of the bar..across the bar, to tilt up the guage to see it better... Nice idea you got there..

[754]

 If you cant get it to bend properly, consider the clubman style construction........
 EXCEPT..... Run the front ends of the bars about 1 1/2 inches past the weld, with a bullet end on them...it would look tits..

There are two holes threaded and ready to go on the underside of the Cognito triple. I don't feel comfortable screwing the whole handlebar unit to the underside of the triple with just blind holes, but I could mount the gauge to those if i had to and mounting the gauge to the handle bar doesn't work out.   Thanks, I think it might look nice if I can figure it out!

Ya I think I see what you mean. I will spend some time this week making some sketches.  I need to get down to my shop and hold the motoscope up there for some sizing reference!

Do you mean for a mounting system to attach it to the cognito triple, the bar bends, or a custom fork tube clamp setup?

[754]

HOw big are holes in the triple and how far apart ?
Making them bigger and 1/2 deep threads or more will hold them.

I saw something just like this at The One Show this last weekend -- as far as the bars go.  The brake/clutch levers were reversed so that the hinges were on the outer edge of the bars. I'm not sure I'd want the gauge to be up against the bars unless you provided adequate cushioning material.  Otherwise the Motoscope will take some rattling against the bars.

I like the idea of the bars Nick shot over.

Someone must have been peeping in my window looking at my sketches!    I like the idea of flipping the controls, but how do you run a master cylinder(less) setup? I would love to get rid of that fugly thing but also would like to prevent myself from dying in a situation where brakes would have been nice.

[754]

You use a Cable to remote master cylinder , under the tank, in the fairing, or on the fork leg are a few places folks put them .Btw Eighties Beemers and Kawi Z1R. Used remote front master cylinders.
 The bike in the pic has the brake cylinder and throttle inside the bars, but that is guite difficult to do.

Great to know, I will look into that!

The One Show bike had a similar set up.  Pretty cool solution for cleaner looking bars.

[GV1390]

Not what you're looking for exactly but, here's how mine was on V1:



Looked clean in my opinion:

I'm in love with this idea! Didn't even know this piece of kit existed. Do it!

I've always liked the looks of those 'reverse-styled' brake and clutch levers.  However, it would seem like it would be a little less natural to grab than the traditional style.  And when I'm grabbing for brakes for an emergency stop, I want it to be as easy to grab a handful of brake as possible.  But that's just me being overly cautious, perhaps.

as 754 stated, drilling holes (not all the way through) on the bottom of the triple and blind-tapping them would be how I'd mount to the top triple....but if you would rather make some type of clamping system that clamps to the fork tubes below the top triple which would hold the bars, the headlight, and the gauge.....make up some drawings and I can see about manually milling it up out of a chunk of aluminum.

its the old BMW system..hide the marster under the tank..and have vire pull to aktivate it...it make it all komplikated and unsafe..bit make the" looks smart" effekt

I think your right about BMW. My buddy's R50/5 has no MC on the bars either.  I'm not sure how it makes the bike unsafe though, just a little more involved to service.

[joeyvans]

I guess it makes a guy wonder..... more linkage, less efficient? Hopefully still  effective?  I've never heard of them, but it would be nice to hear some real life experience with one.

[BLAC]

More complicated, sure.  Unsafe, I dont think so.

Lots of factory bikes have this setup, including the Yamaha Seca 750.  I might actually look for one of these OEM units and give it a go before I spend up for the new unit thats $100+

EDIT: It is very common to have a MC to a single rear disc setup on most bikes... is there a reason that I could not just take a rear MC and use it on the front of my bike?
