Also is it really important to get a velorex with a 20 mm axis (axle) or 15mm is fine ?

No, 15mm is enough
My english is not the best, so you can try it here

Salut!

80000 km avec la configuration normale, marche bien!

Same here,
15 mm on the sidecar axle ist good enough for normal use.

But I think the original frame is too weak. Most SR500 have extra supporting frames.

I have a SR500 combination page online; maybe you know somebody to translate it?

The 17mm axle ist a very low-cost modification.

You can use an original SR500 rear-axle without any mods.

Drill out the 15mm axle with an 17mm drill.
And then push the 17mm axle through the hole an weld it with two points at the inner side of the swing-arm to make sur that the axle will nut turn around.

After this you can use a original SR rear-wheel, including the brake !

I took one with an destroyed chain-wheel-holder (oder wie heißt der KBT auf english ?)

Take a look on the 15mm axle...it may be strong enough, but it don´t look like this

Ok thanks for these first info.

So I'll go for 15mm.

I'm surely going back to you, for more question.

Especially Velorex if you haven't done any modification to your SR500 frame, info are more than welcome.

Marschall, I really like your fork, is it home made ?

No, it is from Walcher, a SideBike Company.

Hi,

thats not a safety question. IF the 15mm axle has a problem, it bends a little. It might break after you bend it back to the original position, maybe.

I am still waiting for this to happen ... the original 15mm axle is still straight and working flawless ...

Considering safety, I would rather invest the money in a double disc front brake conversion.

Salut,Loran!

My francais ends here.
Now to the Sidecar: It is all original, but the Yamaha frame and rear fork are heavy modified by Gunnar Carell in Haren/Ems for a lot of money. Four fixing points on the frame, Koni shocks and white power springs in the front fork as well as Telefix stabilisator and steering damper. Sorry, no pictures, it is for repair for weeks in the other part of town.

Hi Lor@n,

MZ-B in Berlin is a good place to buy, reasonabel prices and they can be contactet online.

Mr Köhler in Fürth is as well ok, but...no email. The 20 mm kit, that he offers, (177 Euro) has cosiderable advantages: 3 ball-bearing instead of 2, a break-mount allready built for 20 mm, and the fork is createt that long it alloges an original wheel-suspension of the SR 500. So getting a spare weel-suspension becomes very easy, and riding comfort improves a lot (no more bumps). I mountet it on my velorex 562, and..no regrets so far.

Mounting the Velorex to the SR 500 You will need the universal fixing kit (MZ-B or Köhler) plus 2 custom made parts (your local blacksmith) plus the upper front fixing plate of the Jawa-Kit (MZ-B).

This upper front fixing plate works perfectly with the SR 500, because it fits to be welded into the SR-Frame in front of the engine crank-case
(the triangle, where the skid-plate is situated). To get an rear lower fixing you may have to create an auxiliar frame, that is bolted into the two suspensions of the main stand. Imagine a Triangle of steel-tube, formed like a irregular Y. Its right arm goes staight from the main stand fixing at the right side back under the muffler, there it is fixed to the muffler support with a flat (4 mm) stripe of steel. The left arm of the Y goes slightly bent to the left main stand fixing. (You have to chop the silly expansion-chamber of the muffler, no more place left for). In this way the rear lower fixing will be at the level of the rear wheel-suspensions giving plenty of space for the kick-starter (less importent, if You mount Your sidecar left hand).

Finaly, the "easiest" way to get an upper rear fixing is the use of the upper rear suspension bolt of the schock absorber. The bolt itself is to weak to support the fixing, so you have to cut it away, then drill a 10 mm hole into the steel-cylinder that supports the rear suspension all across the frame and use a high grade 10 mm bolt with an 14 mm ending with thread to fix an eyebolt. Sounds scary, but my motorbike is
assembled exactly that way since 10 years. The whole contraption even survived a crash (sidecar into an 320 BMW).

Hope i gave usefull information.

Regards, Markus
