Triumph Scrambler subframe build

Hey all. This is my first effort into cobbling together a sidecar rig. I have a Velorex 562 that I've mostly restored after plucking it out from behind a barn in Southern PA. Yes, yes I know. The Velorex is far from perfect. But, for now it's what I'm going with. Perhaps I will transition to another car at some point.

The bike is a 2013 Triumph Scrambler. Clearly the mounting point options on this bike are slim. So, a subframe is in order.

Inspired by this thread:
http://www.advrider.com/forums/showthread.php?t=647434

A lot of it is quite similar, but my setup has a couple different items and is a bit bigger.

Using rectangle tubing works better for me because I don't have a tubing bender handy, and the profile works great for snaking behind the exhaust.

I'll update pics as I can. Feel free to hate on stuff. Here goes.

Tubing bored for threaded inserts.


Inserts were actually weld-on rod ends that I turned down on my crappy lathe and clearanced on the sides.


Tacked in place in case changes need to be made.

5/8" set screw, using the straps from the stock clamp mounts.


Jam nuts to lock the set screws.


Lower section in place


Snaking the rear upright between the exhaust and passenger pegs



Hard to make out, but I have about 3/8" of comfortable clearance all around.


Fitting the upright section, pie sliced and bent on the back to make the bend, will be plated from the back.



Trial and error, grind a bit here and there, no room for mistakes. The Lower section is very long, will be trimmed afterwards.


Hard joint to profile



Welded nicely, wish I had a TIG at my house but the MIG does the job.


More to follow!

The other thread looks totally empty to me. Forum hiccup?

Looks like it's coming along nicely!

One thing I wish my setup did better was the upper front mount. I used a standard Velorex clamp for it. I think it would be better and stronger if a piece was clamped to both sides of the frame, just in front of the engine. No rotation, better strength. This was probably the source of a lot of my alignment woes. That and the sub-par lower mounts on the sidecar that both got rebuilt in a sturdier fashion.

The Dauntless kit uses the frame bolts in the front. Looks to work fine, too!

Another possible improvement: Tie both sides of the frame together for the lower front mount. Probably overkill but hey why not?

I had thought of sandwiching the frame rails with a small section of metal on top and on bottom, clamped on both frame rails. Tying that in to the strap clamp pictured here might help:



Done right it should only reduce ground clearance by perhaps 1/2" and make sure you can still get a socket on the drain plug.

New pics

Well, further progress necessitated figuring out the linkage points, so I had to make progress there.


Lining up main frame for my best informed idea of placement






Tube clamps fabbed, these turned out nice.













Tabs for the subframe stacked and smoothed. Slight dish profile to match the square tube shape




Yes the rail on the subframe is very long, I'm cutting it when I've finalized everything.






Lousy pic, couldn't help it.




Next step is fabbing the front upper frame mount, which is coming along well. Pics soon, stay tuned.

Updates.

Scratch built front mount. This turned out nice.

This support triangulates the subframe from the center stand tabs, blatantly copied from Motoblags build, but mine is a seperate piece.

My first ride with it. I have plenty of detail work left on the car, but so far, it rides great, and I'm thrilled with the results.

Nice work. Would the same mount work on an 02 Bonneville and a Velorex 562?

I'm sure it would, but this one is specifically set up to clear the scrambler side exhaust. I'd make the rear upper mount a bit higher if I didn't have the side exhaust to deal with.
