Topic: Triple tree help

[briancwynn]

I have a cb750 78 and don't know what to do with the triple tree. Do most clean them up or replace them when converting to a cafe racer? I am.going brat style so it kinda works as is but don't want to miss something I should have done in the beginning.  Any alternative tt that can be used that have.classic styling not billet?

Hi Bryan, how soon will you need it? I've got a full compliment of dashes and brackets coming for Cafe builders. I'll be selling them on KickStarter in about 1 week. I don't want to spoil the surprise right now since my video and promotion is being developed this week.

You can PM me if interested or reach me through my website

This was for my 550 but we just milled down the bar bosses.

I went the route of shaving off the handle bar perches. I'm pretty happy with the turnout. Apparently getting a top triple machined isn't too hard. I could have had that done but shaving the perches was free...

Wonder how much cutting those off weakens that part ?

The triple clamp is CAST. whats wrong with that?

It is actually better. It has a shape that is much nicer than "billet" ( a machined chunk of aluminum)
Cast aluminum has other chemicals included to make it stronger.
The rounded shape makes it stronger by eliminating stress.
For instance silicon (NOT silicone) to make it 22% stronger.

Just use a brass wire brush on a drill to remove the old paint.

Sorry wrong post.

Very smart thinking Ekpent.
And those handlebar mounts could be used for instrument mounts.

Just seeing how many broken 750 K0-K2 uppers there are without the washer leads one to believe the metal in those is not the toughest stuff around.

It does not flex much, that could be why.

I've used cb550 front ends with those upper clamps on a number of vintage race bikes. The first thing I did was mill off the bar mounts. These bikes have been hammered around tracks at over 120mph on a regular basis and nothing has failed. The weak point is indeed where they clamp to the fork tubes so be sure to use the D washers to prevent overtightening.

Personally I think the open spaces that appear when you mill them looks pretty cool. The tabs in front that hold the instrument bracket are great for mounting a front number plate on unfaired racers.

Sounds like a good testimonial-Guess I am done wunderin'

Thanks all for the help. I think I will take apart and paint the original.
