Topic: Fork brace options - (CB750K4)

[Yoshimitsuu]

Hey all,

As the title suggests, I am looking for a fork brace for my CB750K4. I know that the fender provides support up there but I’m looking for a bit more while running the fender. All of the options I find are for later CB750s such as the CB750F and the DOHC. I searched the forum and found the ones made by Tkat but I shot him an email and got no response. Tazzori doesn’t make one for the CB750K4. The only one that I found was the Carpy’s one which is just a tweak bar and I have heard that won’t be much help. Any options that I’ve missed for a fork brace that’s available for purchase? Thanks in advance!

I see them all the time on eBay, new and vintage. Shouldn’t be hard to find what you’re looking for.

I don't know of anything available new for the very short lowers on the k6 and earlier.  I recently bought an entire k1 just to get the vintage fork brace.  Keep your eyes open for tubular setups also, as I have used one in the past and it was a good improvement that worked with the stock fender.

I am of the opinion that a good fork brace, some racetech goodies, and brake upgrades, not much reason to mess up your vintage good looks with USD swaps and the like

I have checked on eBay a few times and most of what is there is for the later model CBs or are basically tweak bars. I would use a tweak bar if not for the fact that some have said that it doesn’t really do much. I wouldn’t mind someone proving me wrong as I could order one by the end of the evening if they’re worth it. I reached out to Atlanta few days ago but haven’t heard back. That fork brace looks neat, would accommodate the fender, and many rave about it.

Tweak bars are meant for bikes with extended fork tubes...chopper stuff.  All a tweak bar is gonna do is eliminate at least 1" of valuable suspension travel.

Here is the K1 I bought mainly because I had to have that fork brace.  Sorry it is hard to see in this pic.  I don't know the manufacturer yet, but I am guessing Telefix...I know Telefix made a brace for early 750's at one time, but they are long gone from the website.

Also, here are a couple old threads on how to make one from 754...

Also, the other options are tubular or a bent aluminum plate one like from old dirt bikes...I have both and will try and remember to get you some pics next time I am at my shop.

Not sure what that is but I have a Tarozzi on my K3.

Just get a set of lower legs from 77/78 750k, everything will bolt right on.. and they make braces for them.

a bent aluminum plate one like from old dirt bikes...

One of my buddies had one of those aluminum plate fork braces on his Suzuki 80, but it wasn't drilled for the lugs on the fork lowers on the 80, so he attached it with only one bolt on each side, instead of two. One day, we were "racing" down a dirt road near Mud Lake, with him in the lead, as my Honda C200 struggled to keep up, when he suddenly came to an abrupt stop. As I was right behind him, I had no time to slow down, and I rear-ended him in a glancing blow to my left side. Other than my foot peg getting bent straight back, there wasn't much damage. Turned out the two bolts had worked loose, and the brace rotated forward and sucked into the front tire, locking the wheel.
Yosh, I have a pair of K7 lowers I can part with, if you want to go that route.

Stev o measure your forklegs, might be K 7, the brake is..
 K7 tubes are hard chromed to the top, K 3 are not..

+1 to what 754 says, brake is f0, f1, k7, or k8 as are fork tubes, not sure about the lowers.

And the reason fork braces are scarce for k0-k6 is because the lowers are so short, requiring a long arch to reach over the wheel, let alone fitting some kind of fender

Will do, had not considered that.   The caliper came off my shelf during assembly and not with the bike...
