The OCMD-afflicted never sleep....
Inspired by this:
So, what is it? you ask. It's a frame brace developed by the Japanese high performance firm HARC-Pro. It goes where the lower subframe mounts to the frame and acts to reinforce the frame.
Now then, presenting the "mikstr-ized" version:
(NB: Disregard the HRC sticker, it's on there as I have a stock of them.... need to use them somewhere, lol)
Will try it and see if/how it affects the bike.
Will keep you posted (of course, have to wait for bike to get fixed and be back on the road, which should be in a couple weeks, at least I hope)
P.S. A special thank you to Jack Flash for his help in getting it welded and entertaining my bottomless well of OCMD ideas, lol

I used a section of aluminum tubing for the main section (20mm OD, 10mm ID), then mated it to two section of 35mm long (19mm OD) M10 threaded collars. These are spaced apart by small wedged of cut Al tubing (25mm OD, 20mm ID).... all welded up.
as for hitting the shock, the answer is no (the small wedges added to guarantee sufficient clearance). The bolts are black Ti.....

I have no drawings, sorry; this is the veritable definition of homemade.... The only missing element (from material specs above) I can share is the spacing of the two threaded collars, which is 224 mm outside end to outside end.

The addition of the HRC sticker ought to be worth another 5km/hr top speed at least!
I am humbled by your fabrication skills!
Here's my best effort (a prop for the front of the tank during service)! An HRC sticker would also improve the performance.

This isn't a prop-rod thread. We had one of those about a year ago. This is a thread to give Micky **** for bolting something not made of carbon fiber on his bike and, so far, I'm the only one on topic. Come on people.

I'll just go back to refining my HRC prop then (and being made of wood, it is a natural form of carbon fibre already).

Remove your new carbon prop stick, less the fibers of course.

I though our frames were supposed to flex!
I read some info on here by Jscobey about it and If I recall the idea was poo pooed.
Not being negative, just curious.
Mike,
Let us know what happens when you get to try it please.
I can't help wondering what effect it would have on the suspension with the frame flexing less, still interested though.
It's a shame that you don't have any drawings so that we could all get one made if they are any good.

It installs between the subframe, where the lower part of the subframe mounts to the frame. So, you just need two measurements. Measurement between the subframe and a measurement for the offset, so it doesn't hit the shock. Super simple to fabricate. Looks like he used 5/8" or 3/4" tube.

But, I'm just guessing.

While yours is obviously 224mm, my thinking was that this measurement may vary a bit frame to frame, so I didn't want to give out any misinformation for anyone attempting to fabricate this doohicky, thus left it out of my guess.

What are MTB handle bars?
Please excuse my ignorance.
On another note I can't help thinking that this brace would also have a certain amount of flex that may be compatible with the frame flex especially with side loads on the frame with cornering.
I for one enjoy the fact that the frame flexes on the VTR when pushing on and enjoy the feel. Sort of like feedback that let's you know that you are pushing the boundaries and it is time to back off.
Some of the later bikes that I have ridden do not have this feel and can catch you out if you are not on your game.
Still interested though as I think this brace would still help to retain the feedback, but step it up a notch or two.
If anyone gets around to fitting this and experiencing it before Mike, please let us know your thoughts.
I am almost certain that there are a few candidates on here that will try it soon.
