Bar clamps

Post by Hubie » Tue Jul 07, 2020 2:57 am

Question from a newbie with a 2012 retro model (has the old school steering damper knob).

Someone fited some ugly risers on my hack and I want to return it to original. Will any standard set of clamps do the job or will they potentially foul the steering damper?

Cheers,
Hubie.

Cannot answer your specific question. But I can provide a couple photos of my 2000 650 which I believe is the same as the later models. As you can see, the height and style of the riser(s) you chose may or may not interfere.

Although you did not ask, I will make a suggestion. I would suggest that you remove the mechanical damper and install a VW hydraulic camper. Sean offers them in the Gray Market and several members have installed them. I made my own mounts based upon Sean's design and bought a VW damper. Major improvement in the rig. Slow speed maneuvers required less effort and bumps and jolts from the road coming up thru the bars was significantly reduced.

I made an aluminum cap/plug to cover the hole in the stem where the damper rod was. Here is what it looks like now. The clock was a later addition, as was the black headlight shroud (dash).

Rather than start a new thread, I decided to piggyback on this one.
Today I was wiggling the handlebars trying to figure out an unrelated electrical issue and this happed...

They were loose on the trail on the Turkey ride and figured they just needed some tightening, but they were apparently cracked as evident by the rust.

So anyone have any suggestions for good bar clamps? I have the knock-off Rox Risers so just want a strong simple bar clamp, it doesn't need to have any rise.

I checked the bolts and they are 12mm and the handle bars are 7/8".
It's a shame as these clamps are heavy as F, I don't think I will find any as solid as these, unless I can get a reasonable priced stock pair.

Well, that will teach you not to wiggle your handlebars. Bet you won't do that again. :roll:

Are those studs cast in or are they threaded in? The risers appear to be aluminum. I would try to remove the studs and install new ones if I liked the risers that much. Can you drill them out, clean out the threads and install new grade 8 studs?

It also looks like there is enough meat in the bottom half of the riser to drill thru that bottom piece, counterbore it and and use socket head bolts instead of studs. This would allow you to simply drill out the broken studs without concern for damaging the the threads. I've had risers on other bikes that used socket head bolts in that fashion and worked fine.

OK after some Amazon and Ebay research I went with these.
There are not a lot of options for 7/8 bars with a 12MM bolt.
If you are willing to go with 1-1/8", your options increase, but I want to stick with the handle bars I have now.

Cast or pressed, not sure, but they ain't coming out easily.

Nope, very heavy steel. If I bothered to cut the bolts flush, then drilled and tapped them they would be the world's heaviest duty handle bar accessory mounts.

I don't like them that much, all of those options sound like way more work than I want to do.

The mount is offset from the bolt holes, so I don't think that would work.

Note that these handle bar mounts have taken two impacts that were hard enough to bend two different sets handle bars. Both times, it was reversing in the woods, and the handle bar end caught a tree and put a goodly bend in the handle bars. After the second time I left the handlebars bent. So I think this is a case of hard use (abuse?), not a defect in the mounts themselves.

I just cancelled my order for these.
I just noticed that the bolts on the old one are only about 30mm.
The bolt length on the new ones is 58mm.
I neither want to space them up higher with a stack of washers or spacer, nor do I want to do the same beneath the triple tree to make the longer bolt length work.
Back to searching. :x

Rich, I found these on ebay and, if I remember correctly, I threaded the appropriate length bolt from the bottom of the upper triple-clamp into the handlebar riser.

I looked through my ebay purchase history to share a hyperlink with you, but I guess I bought them so long ago that the purchase dropped off of my history.

Rob, the only way you could talk me into using those old single-bolt risers is to clamp them onto some Rox risers (or a similar product) to make handlebar removal significantly easier. Having to remove both risers and all switchgear from the handlebar so you can slide off a broken riser is a real pain.

Naw, I was just going for a faux Cyrillic joke label, though I'm told that it could loosely be translated as "I grew". :oops:

I'm struggling to find one that works.
Here is the issue...

Most have 10mm holes for mounting the riser to the triple tree...the stock ones use a 12mm hole.

If they have a 12mm bolt it's pressed in and too long for the Ural application.

Many that have 12mm mounting holes are for 1 1/8", I'd have to change out the bars or use shims to fit my 7/8" bars. I'm leery of using shims.

If anyone knows of a bolt-on solution, let me know.

Metal bushes? Reduce 12mm to 10mm? Cut off of piece of tube?

I did some more measuring...

The shoulder portion on the mount that fits into the hole measures 12mm exactly.
I assumed it was an M12 bolt.
However, I checked the snapped off threaded portion in the thread gauge and it's M10-1.5.

If I go with a riser that uses an M10 bolt do you think it would work?
I would use Grade 8/Class 10.9 bolts and torque it down to what I thought the mount could take, as the mount would be acting as the "nut."

So with clearance for an M10 bolt inside and an OD of 12mm the bushing would have to have a little less than 1mm wall thickness.
12mm copper pipe comes to mind, as that has about 1mm wall thickness.
I'm not sure how thick the triple tree is, I'm guessing at least 10mm, I haven't taken the headlight shroud/tree cover off yet.
