Hey guys and gals,

Just in case anyone else is planning this conversion but haven't yet gotten the steerer bearings from All Balls Bearings, they currently don't have a supplier that allows this conversion to happen.  They told me that their supplier just redesigned the bearings and it no longer allows for any sort of modification but they are looking for a new source.  So, at the moment, it appears that the only alternative is to machine down the R6 stem to accept the CB550 top bearing.  Does anyone know if there's enough material for this to be done safely?

Yeah, if they're both 30mm at the base, does that suggest that you can press the stem out of the R6 unit and press the Honda one in, then use a spacer for the top tree?

Haha it's never easy is it?  I wouldn't want to turn the steerer down either.  The Honda's stem is steel and welded in isn't it?

The stock upper bearing OD is 48.5 correct?  Can this be shimmed down to something more common and still maintain the 26mm ID and do it safely?  Looks like another call to the good folks at ABR.

Im having a custom tree with 550 stem and  R6 offset and spacing made . Not a bad price at all , and the guy doing the job will offer this as a item you can order from his webpage later , and he also makes really nice rearsets btw ( and for aprox 120 $ they are a bargain ) .

I'm definitely interested.  Please post the link/pics when you have them!

Anyone want to tell me what the cost would be for a new steerer and pressing it into the R6 triple?

Thanks!

I have had a Honda 750 stem removed and pressed into a GSXR1100 bottom clamp.....  I see no reason that the same can't be done here....

Just picked up 1997 CBR front end tonight. I plan to use stem from my F1 unless I can have one machined for cheap. Press in and out is the plan. If by chance I am done first I will let you know how it goes. Love your build do far.

All i can remember is that it was a very tight fit {was a while ago} Maybe some sort of adhesive.?
Doesn't really matter now as i am having some billet triple clamps made up with a better offset, so it won't be used now....

Well that sucks :/ I finally get to the point where I'm ready to buy the bearings, and now they're not available anymore.

I'm emailing ABR and getting some details now. If I don't get the info I need, then:

Would a bearing place be able to mix'n'match or make the bearings for this, given the dimensions?

From what i understand Honda used standard bearings. Bearing supplier should have no problem cross referencing it for you.  Good luck.

I got a reply from ABR as to why the bearings won't fit this application anymore:

"In a fork swap application the race was needed to be modified to accept the
bearing from the other set up. The race is now thinner and cannot be
modified to accept the other bearing. I do not have a time line as of right
now unfortunately."

I think I may try my luck at a few bearing shops around here. Sucks the supplier redesigned the bearings, as I JUST acquired the last few pieces of the R6 front end and I'm ready to swap it in -.-

Oh, know how many bearings there are in that setup?

Hi,

I've been working with spdygnzlz on his conversion. I machined his hub/brake adapters for him. I have another option. Looks like All Balls 22-1012 is a 30mmx48mm tapered bearing. It's easy enough to machine a sleeve to change the stem's 48.5mm OD down to 48mm. This would be cheap and easy.

Lots of other options too, as mentioned above.

(Sorry to keep this hijack going Jimmy, but you've become the "go to" reference point for this conversion. Thank you, by the way!)

So getting JUST the ABR #22-1012 and machining a sleeve for it.. 30x48 (what's the width supposed to be? 15?)? Isn't the OD supposed to be 48.5?

Sorry for the seemingly simple questions, I'm fairly new to front suspension and I can't quite picture it in my head.

yeah its a .25mm thick sleave that goes inside the upper bearing mount on the frame to accept the 48mm OD outer bearing shell (2 x .25mm = .5mm) bringing the total to 48.5mm OD.

hope that helps

Me too.  I wondered if the vid was admissible in court.  (It will be... someday.)

Way to set a behavioral example.  Rules are for others to obey; ergo: "outlaw bikers".  (Yes, I did that, too...when I was 17-18.)

Looks like a really nice road to motor down, though.  Being in Washington, I wonder how often it is dry?  Did I see just enough wet patches to spell trouble! ;D

Washington is the most climatically diverse state in the lower 48. We've got everything from glaciers to rainforests to deserts.

The Olympics put us in a bit of a rain shadow here in the Puget Sound region.  That said, winter is dark and 8 months of the year are pretty cloudy and damp.

However, what we generally don't tell folks (because we don't want too many more following us here) is that a normal summer is (or used to be) cloudless from the sencond week in July until mid-September. Almost zero humidity, temps in the mid-70's - pretty outstanding compared to the hot, muggy summers of my youth in New England. And, if you miss the heat, you head over the Cascades to the desert.
Take care,
David

...hopefully the local constabulary has better things to do than surf motorcycle forums looking for idiots posting incriminating videos,

Today, yes.  But, as government is allowed to get larger and larger and laws continue to be made into an ever expanding ledger... law enforcement can be done from an office desk and an internet search.
Hope I don't live THAT long.
