After spending endless nights thinking of how to mount my rearsets I think i came up with a pretty good solution. It's cheap, looks great, and adjustable too.

It's a different version of Greg's way of mounting them on a 400. He has examples on his site http://www.ohiocaferacers.com/
His look like this:


So the first thing I did was cut the mounts and tubes for the passenger pegs off. That looked much better already.

I liked Greg's idea of using clamps, because you don't have to weld anything to the frame, but I couldn't find any nice looking clamps.
I then measured the frametubes, they're 25.4 mm on a 550. This is exactly the same size as a mountainbike bar (i used to be a mountainbiker ;D). So I went to my mountainbike and took of the stem. It was too short, but it did fit.
Luckily you can get these stems in all kinds of sizes and length. And they are cheap too, I paid $10 for a secondhand pair. You will only need 2 stems, one for the brake and one for the shiftside. They are strong enough on their own, so you don't need two clamps like Greg's solution. A mountainbike shop will have these stems in all kinds of colours and sizes.

Get a stem for a normal bar (25.4mm), not an oversized bar.

I bought 2 identical 11cm. stems, with a 5 degree rise. The "rise" in the stem normally makes the bars a bit higher on a bicycle, but since we're using the stem "on it's side" it offsets the pegs to the side a little.
The stem looks like this:


The hole on the right normally holds the bars, that part gets clamped to the frame. The other side has a hole too, that will hold the rearset but it was too big for my rearsets so I had to find a spacer.

Because I hate fabricating stuff, I used a 21mm socket (from a Ratchet Wrench) as a spacer. You clamp the socket in the stem(left hole in the pictures), and bolt the rearset to it. If you have machines you could make a real spacer, but this works too if you can find a socket that fits good.

I used Tarozzi universal Rearsets.


The cool thing about using a stem is that it looks really clean, and you can decide where you want the rearsets. If you buy a longer stem, and clamp it high on the frametube your rearsets will be very far to the rear and high up. If you buy a really short one and put it low on the tube, they will be low and more to the front (more like the stock footpegs).
If you buy without a rise the pegs will be straight behind the frametube. If you buy them with a slight rise you can choose if you want the pegs more to the inside of the bike, or you can flip them over and put the pegs a little futher to the outside.

I'll try and borrow a digital camera and make some pictures of rearsets mounted on the bike, because this is getting confusing ;)

Woah, awsome hack!  I love stuff like this.

Kudos on the original thinking.

Someone dug up the tread huh?  ;D

Here's some pics. The shifter rod is off here as it's being welded. But that's the same for all rearsets anyway.

Until I saw the pictures I couldn't quite figure out exactly what you  meant.
Its a real good solution and I think we may see a bunch  of bikes with 'mountain bike' footrest hangers. I have a feeling my 360 may just get a set  ;D

It's just that i'm really bad at metalwork, so I had to work around a few things.  :D

My colleague (a harley rider) calls it the Polish bike. Because I have so many parts bolted to it that shouldn't be on a bike. The trottlecables are from a BMX bike. The box for the electronics is a cake form, I covered it with mesh that I sprayed gold to make it look better ;D
There is also a lot of brackets made from parts for doors and windows (I found a big box of those)

I would say if anyone wanted to copy my idea for the rearsets, I would be proud to have contributed something to the forums. I've had some great help from you guys, and couldn't have finished the bike without this place.

Your stem solution is truly ingenious!

top notch idea and really clean looking.  Very adjustable too.

Is kickstart swing affected?  I know many rearsets block the down stroke.

I can use the kickstart without changing it somehow. But my pegs are pretty far to the rear. I'm pretty sure it can be made to work most of the time without major changes.

Someone asked about the costs:
I paid $10 for the stems, and about the same for the spacers. That's a lot cheaper than the Tarozzi brackets for a 500 (about $90).
I went to a bikeshop that specializes in expensive mountainbikes to get the parts. A lot of guys change out these parts on their bicycle for a better brand or a taller or lower stem, so they should have a lot of old ones laying around. They had about 25 old ones where I went, and I could have got them for free.

I am wondering if the pressure from the legs will make the stems move around the frame a bit causing undo stress on the pieces in between.  Yanno, kinda like the chopper kickstands slide around the frame at times.  My guess is pins inserted through the stem and into the frame would help alleviate that possible issue.

I thought about that when I started the project. My conclusion was, if the stem is strong enough for the total bodyweight of a mountainbiker going downhill at 40mph, it's strong enough for my weight on the peg.

I don't notice them moving, but i'm a pretty light guy.

You could also make small vertical ridges on the frametubes to prevent them rotating. Mountain bike bars have this sometimes as well.

I second that.. Now, until I can actually AFFORD those rear sets, the cheap alternative just gives me more incentive to continue to save up.. ;)
Cafe Racing is mainly a matter of taste. It is an atavistic mentality, a peculiar mix of low style, high speed, pure dumbness, and overweening commitment to the Cafe Life and all its dangerous pleasures. I am a Cafe Racer myself, on some days - and it is one of my finest addictions. ~H. S. Thompson~

yea, i thought the cheap alternative mounting bracket coupled w/ the uber expensive tarozzi parts was humorous.   :D
