How do you think it would go on a Beemer /7 then ?

A bit like this.

Done that search already - there are better examples on youtube of all things but most are right hand fitting.  It seems to involve the making of a complex looking bracket that runs much the whole length of the bike too.  Beemer frames are a bit weak for sidecars, as are the forks and - on mine - the brakes (as Graham will testify I am sure).  At least it still has Timken bearings where it matters.

And what with the vintage art, attached, I think you are on to a winner. Chelsea, here you come.

Don't worry, you're only going to take your kids in it.

Steve - what the f**k are you on about

Better choice than sticking it onto an MZ....easier for a start 
Proper sidecar tyres available too, 19" and 18".

It just so happens I have some fittings for BMW....might fit yours.

Excitement here in Lampeter - thinking R80 bevel boxes and stuff.

Take the bike back to R100/7 standard with wider/higher bars and all, 'normal' footrests, lose the fairing etc etc.

I was responding to Rob's suggestion regards potting mix and some nice bulb,...

I would try it with the standard bevel box first.
Velorex very light.
I did lower the gearing on my Bonnie for The Dragon.......there was no need !
Went around Ireland 2 up towing a trailer and all the gear. No problem !
Popping along at 60-70mph easily.

My thinking is that the R100S was the highest geared of all /7s - they actually reduced the gearing on the RS but made a few internal changes to make use of the higher revs.  It can be fairly high stepping as it is.  What it will need is a new clutch and the rear crankshaft oil seal replacing first however.

I don't know how the standard forks will cope but given the cost of fancy leading links etc, will have no choice but to try.

[002]

Several choices to beef up the forks.

Stronger springs
Spacers
Old Valve springs on top of original springs.
Or a combination of the above....within reason.

I have done all three at one point or another and found it can work quite well.

And heavier oil.

I was thinking more about the side to side pressure on what are only 35mm forks rather than the uppy downy thing 

It  has a fork brace on mind, they were terrible with only the pressed steel thingy on.

Ah Yes ! You could do with one of those.
