seeing as im getting old and decrepid decided to go down the sidecar path and this is what iv come home with ,its a djp of fk knows yrs , f/ glass body that needs a little bit of work to the floor (stuff all) ..now iv never had anything to do with s/cars so any advice would be great ,been looking at the clavits for attaching the mounts to the bike frame .. here in qld if weld lugs onto frame they have to be engineered/inspected ($$$) , the boat will have to be cleaned up and repainted , the seat will be coming out due to wanting to keep my cheap solo rego, had to chose between a 1986 bmw k100 needs a bit of work but got the parts but a sub chassie would have to be bought ($$) my tdm850 ,on the rd but the mounts would be very complicated and $$$ , and horror of horrors my xs650 … I like riding and leaning it BUT it would be the cheapest and most easily converted , its up graded to 750 , has a 7 plate clutch and also a heidens hyd clutch +plus have a xs1100 f/end that was on a xs650 (so a easy change over) , any for once managed to get some photos (not in my shed but sellers before loading)
Hi FLEA,
no worries, I've built 4 of the bastards for XS650s and one for an XS11.
Here's the final evolution of my XS650 sidecar subframe design:-
Back part of Subframe:- make from 1-1/4" x 11ga square tube.
2 stubs bolt into frame's centre-stand mounts, (use M10s or the stock centre-stand pivot bolts)
& are welded to a crosspiece that Tees onto a fore and aft rail that'll run just under the bike's exhaust.
Rail runs far enough back to reach the rear lower sidecar attachment and runs forwards to below the front engine mount.
Front part of subframe:- make from 5/32" x 2" flat bar and 1" sch 40 pipe.
Flat bars bolt outside front engine frame bolts.
The frame bolts will need to be longer so use the lower bolt in the upper position and make a longer
lower bolt from threaded rod. Flats go downwards and are hole-sawed 1-1/4" diameter through to fit the pipe.
(1" pipe OD is 1.305" but hole saws cut big)
Pipe sticks out to meet the rear subframe's fore & aft sq tube. Hot-bend a sq U-shape from flat bar & weld to the 1-1/4" pipe's end.
Drill thru U & sq tube to join them with an M12 fastener.
Drill through the fore and aft subframe to suit the lower sidecar attachments. (I used M16 Heim joints)
As this sub-frame is a bolt-on you don't need no steenkin' inspectors, right?
I also made my own frame clamps for the upper mounts but it's a load of work, I'd say buy 'em from Velorex.
Good luck with the biuld
