XS1 wheel on an xs650

[DogBunny]

With all due respect DB I think you're missing how the bracket installs, it's nearly hidden behind the fork leg.
this would be the view from BEHIND the leg.

It will show less than an axle to fender mount strut would.

Yes, for the longest time, that's exactly what I thought. But one day, I finally figured out what you said.
Perhaps I was harsh, but aesthetically, I still don't like it. The adapter itself is fine. I just don't like the caliper mounts, especially the one that blocks the view of the front of the brake plate.

Did you ever pull this off?

Is it possible to put the XS1 hub on the XS650 17mm axle? Custom bearings?

Unfortunately I did not.
I would have loved to, but a good friend found me a MotoGuzzi that I have wanted since I was a kid, So I sold him my XS650 for what I had into it, and he went a different direction than I was going with the bike.
On a cool note, I still get to see the bike sometimes and he made it wade cooler than I could have.

Actually, I still have the brake and front wheel sitting in storage. It should probably go to someone else who needs it.

You might have to wait a while for a reply on this moribund thread. @Big John has not been sighted for 9 1/2 years.

It actually pinged my email

They are for late 35mm forks, the caliper mounts are behind the fork tube.
Tried for a while, could not find a pic of one installed...
prolly no worse than the torque arm used on other designs?

Me? I have a 71 that's missing the front drum wheel.

You definitely have a point there.

From the side, it would look exactly like this, except the caliper mount holes would not be empty, and maybe the builder would finish of the mounting bolts with acorn nuts.
I honestly think that an axle to fender mount strut would look better.
But not crazy about either one.
I'm not a welder, but wondering if you filled the lower fork leg with oil, and then had a skilled aluminum welder add a stopper tab, would the oil help disperse and dissipate the welding heat enough to maybe reduce the chance of the fork distorting?

Torque arm to the top bracket, cut off the bottom one?

Kudos on a creative solution...

... however, we agree that the Motolana adapter is as good. Thing is, you drilled a hole into the brake plate for the torque arm anchor bolt, thus molesting a rare part, so this one is a hard no.


BTW, stellar Photoshopping. I think I know how you added the strut, and I added another one above yours. But, how the heck did you add the shadow?
I do my Photoshopping using an ancient program called Adobe Fireworks version 11, which was released in 2010. Fireworks was discontinued in 2013. Fireworks 11 is lightweight yet fairly robust and versatile, and pretty easy to use, and I got it for free. I dread the day that I get a computer that won't run it and I have to learn something else.
EDIT: I figured out the shadow, added one in red, and changed my picture.

Thanks, good to know for when the time comes.

Here's a little idea of my own from a few years ago. I forget exactly what these clamps are. Maybe meant to be clamped on motor shafts? There were a lot of different kinds. Purchased probably from AliExpress, or maybe McMaster-Carr. I bought two different sizes, intending to use the one that fit best.

Remove the excess material and you have a nice clamp-on stopper tab.

This is what it would look like from the side. Sketchy? The slot in the brake plate is tall, so maybe gang up two of these clamps?

2M put the kibosh on this idea for me when he suggested that the clamp would rotate in use. I question this. How much could a tight-fitting tab rotate before it got cocked and bound in the slot? A couple degrees?

'fraid I'll have to agree with Steve, I think they're gonna rotate.

Sure, hit me up with some contact info. I even have the SR500 bracket to make it work with the XS650 as well. I just never rebuilt the brake and got buried at work.
I am not on here much obviously, but I will try to remind myself to check back

These pics came up on Facebook yesterday, posted by a U.K. owner. Same idea as @Jim and Jimmy Eckman, seen in posts 29, 30, and 39 in this thread.
This one looks maybe a bit flimsy, while Eckman's seems a bit obtrusive. Maybe something in between?
