"you don't turn in you turn the bars the opposite way to the corner"

Funny you should say that.....

My wife had a friend over to stay over once and she was pestering me to take her for a ride, so i thought she must have been on a bike before and ended up taking her for a ride. The first corner we came to is a slow 20 mph left hand corner and she sat bolt upright and i nearly fell straight off the left hand side, the bloody bike dropped like a stone.....

We both survived upright but i gave her a quick education on the side of the road before i went any further with her on the back.....

After a few close calls, when I leaned left and the rider leaned right, I always told the ladies to wrap their arms around my waist, wrists locked together, and keep their boobies pressed against my back, so they could move with me rather than against me.

On these older Honda's the only way to keep the twist out of the front end is to put on a fork brace that goes on the lower legs. It must have an arch to go other the top of the fender. The fork brace will also eliminate that annoying brake caliper from binding as well when you turn the bike, when moving it around the garage. The only thing that keeps the lower legs from twisting is the axel.

Below are links to a couple of different manufactures. I have not used either brand, but I am sure with in the next two months I will be buying one of them. I have talked with Fast from the past and they say they don't have one to fit the 69 to 76 CB750k. They told me it need to have an arch to go over the top of the fender.

If you find something different let us know.

Fabricating a brace for the early bikes is very doable, but quickly becomes much more complicated if it has to accommodate the stock dust boots, as well as the stock fender.

Unless you are married to your fork lowers, nab a pair of later model units off eBay and call it a day. . .

Not that easy. Besides the diameter of the top of the leg being different, and the leg being shorter, the internals on the early forks (CB750) are completely different and the lowerlegs will not interchange. The early ones had upper and lower bushings that fit between the tube and the leg. The later ones, the tube rides directly in the leg with no bushings. Hence the ID of the later ones is smaller than the early ones.

I posted before about the billet fork braces from Tkat.com. After much begging he started making the fork braces for the SOHC CB750. Really nice stuff compared to the cast aluminum ones I have seen/used before.

Was that on adifferent thread? I remember responding to your post. That Tkat.com product is really well thought out. Hope people here give him some business. And the design allows him to make whatever elevation on the bridge is required, as part of his machining process. It accomplishes the same as my brace posted earlier. But my elevation is acconplished with removable spacers which aren't as solid as having it be part of the clamp.

I sent tkat.com an email so hopefully he will respond.

i sent one sunday and got a response on tuesday so you should hear from them soon

That's the beauty of the factory brace that came on our Hondas and damned near every other motorcycle offered to the public over the last few decades. It's almost as if the design engineers knew what they were doing.

The Tkat brace retains the use of factory boots, and clears the fender.

What were they thinking when they mounted the K7 brace in rubber bushings, which rendered it useless??

Roach · « **Reply #242 on:** February 22, 2011, 10:06:09 pm »

so im looking for a brace for my 78 550k. all i see on fast from the past all i see is 500k ones are they the same?

somesuch · « **Reply #243 on:** February 23, 2011, 08:26:56 am »

On tkat.com there is a fork brace measurement sheet with all the dimensions that he needs to make a brace. Since the 550K is very similar to a 750K (if not the same...I had the forks from one, and the lowers were the same) he can probably build you one.

socalenduro · « **Reply #244 on:** February 23, 2011, 08:17:47 pm »

and in my email he said cost would be around 125-150...
seems pretty reasonable for custom made

scottly · « **Reply #245 on:** February 23, 2011, 08:29:50 pm »

I would think that to be very reasonable for custom made. Any pics?

I can't get over how cool that is. Great design, adaptable to anything. $150 is cheap for that.

cobrajunkie · « **Reply #248 on:** February 24, 2011, 07:55:40 am »

Nice brace. The Tarozzi I got from Fast from the Past is 100 bucks and is a gorgeous piece. What years/models do they not carry? I'll email them to let them know that there may be a sizable market here if they decide to make them.

plug1 · « **Reply #249 on:** February 24, 2011, 08:10:53 am »

I have yet to find a brace for a cb400f.
