Rotopax mounts for KTM racks

[ktmkevinm]

My friend and I came up with what I think is a good idea but I don't know how to post the pics. How are you guys doing it?

The idea is RotoPax mounted to this and then some Wolfman bags (more RipWrap!).

Impressions? Suggestions?



BTW, new owner. Picked up my new old stock 2010 White last week. Love it. It's like a Tuono got a F650GS Dakar pregnant and they had a wild kid. Been reading this board for awhile now and y'all's opinions factored a lot in my decision.

Any chance of getting an electronic copy of this drawing? I wouldn't mind running this through a CNC here at work.

What size tank is that?

I really like this setup, thanks for sharing!

I need to take pictures of the mounting plates I fabbed out of the big ATV one. They hang on the back side of the rack system. Bent to bring the roto lock moounting surface close to even with the rack and notched to lock in with the top rack brace. Once you put a two gallon pack or tool case on and twist the handle compression holds in place. So no tools needed to install or remove quick and easy. Once installed if you don't have a passanger through a true mule pack saddle over the back for a easy soft pack with plenty of volume. With any of these I definitely recommend decatting or going to after market exhaust before you strap 4 gallons on the back. As on of the more senior riders here said one day. Who's riding the bike with a bomb strapped to their ass?

But the clamp i found are 3/4... too big, they are loose, wich is not good
Alternative could be to put the sheet on the other side of the rack, then the rotopax clamp will hold everything tight when locked

1/2" conduit clamps are the right size. See: Post 12 of this thread

Thanks !
I also baught 1/2 clamps... too tight !
The tube are 18mm and 1/2" is 12.7
I use the stainless touratech panier holder.
I guess I'll use some tape a thin vinyl tube... But I'll check again the 1/2, thanks

Aluminum is still the plan; just haven't had any problems with the plastic yet...

Got the happy trails pannier mounts to make that whole thing quick release, haven't gotten to that yet, either.

I thought about the sandwich, but I have seen a couple of reports (come to think of it, one may be in this very thread...) of the bolt breaking on the rotopax mount; if you do the "sandwich" thing that leaves more bolt unsupported as the thickness of the case/can plus the rack is greater.

My memory may be faulty, the 1/2" metal conduit is an id measurement, so the outside diameter is very similar to the od size of the 18mm tubes. Also, the conduit clamps enclose only a little more than 180 deg. of the tube, so the fit is a perfect snap on fit. I use those clamps only on the bottom of the plates.

You must have got the last set Happy Trails had, ordered mine 4 weeks ago and still waiting. They said they ran out and are waiting on their supplier.

It happens, but would like to finish the build.

[Alleycatdad]

Actually I waited about 4 weeks as well...

This is what the 1/2 looks like on m y bike

To me, it's too wide open to be trustable (I could use some spacer)

And I found some 5/8 wich look better


Less rubber, but still some vynil protection

4 of them and the sandwich plan may be the solution I go with (but working on another idea)

1/2" is generally the ID of the conduit, so the OD varies depending on whether it is e.m.t. or rigid pipe (which, as far as straps are concerned, is the same size as PVC conduit). They are frequently labelled TW for thin wall and HW for heavy wall and the difference between them is basically one standard conduit size. In simpler language a 1/2" HW is a similar size to a 3/4" TW and a 3/4" HW the same as a 1" TW, and so on. The HW straps are usually made of heavier material. Sorry users of the metric system, this info is from the dark side only.

Now that you know more than you ever wanted to about conduit straps, let me say that I personally wouldn't use one-hole straps to mount anything that heavy. They don't hold conduit onto buildings very well, and most people don't take their homes on washboard two-track at triple digit speeds (although that sounds like fun).
The steel wrap around style with vinyl insulation are actually stronger than they deserve to be, and won't let go, just maybe get loose, but don't use the aluminum ones. Remember that these are designed more for holding wire looms, as the packaging photo suggests.

I agree. That is why I used thru bolts with 1/8" aluminum strap on the top mounting points.
