    Claude should answer that , as he has before but a Ford engineer I know told me exactly what Claude did.
    Leading arms ride better and the majority of touring sidecars in production use them, trailing is more HP and less problematic, I've had 3 trailing and 1 leading the leading was the EZS Summit rode like a big German sedan and caster increased as it was compressed.

    Which way is easier over rough terrain, pushing a wheelborrow or pulling it? :ear

    I reckon there might be a reason why VW beetle front suspension was (and still is) used widely for off-road buggies and cars.

    So I was figuring I'd stick with that trailing arm design/principle when building mine (still gathering info/data and haven't started yet).

    Now you guys have me all confused

    VW front ends, AKA: Beam front end. They are not commonly used in off road in new builds. Except for a couple of limited classes, A-arm front ends are now the off road buggy standard.

    I had the privilege to co-drive in Baja Bob Gordon's Chenowth for the 1st 4 years of the NORRA Mexican 1000 in which we won 3 of those 4 years! Here is a pic of me & Butch Arciero in Bob"s "beam car" known as "Betsy":

    RIP Bob, you are missed.

    I wasn't implying they are the standard/rage. Just that they are still used and surely wouldn't be if it wasn't a good/decent design?

    Like I said - I'm confused now as to which way to go on the sidecar (trailing vs leading)

    This should really raise some eyebrows ..
    This is the sidecar suspension I’m using on my next build.
    I built it for my first build and it worked very well !!
    SIMPLE,SIMPLE,SIMPLE !!.

    This isn't rocket science ! Your way over thinking this ! Just build a Ural clone DMC has succeeded with that philosophy.
    Why do you want to build your own ? Is this going to be a square tube, no miters ,butt joint obviously no structural welding experience deal ?
    I put people and things I care about in my sidecar and haul them all over hell, I like to think its well built .
    Good weldors are worth the money !

    Like I said limited classes (classes 12, 1600, & 9) still use them but those classes are dying out rapidly, I haven't seen a Class 9 entry in Baja for several years. Most popular limited class is Class 10 that uses A-arms and Ecotech motors. State of the art in Class 1 (unlimited). I was the "Co-dog" with Terry Householder in this car for 2 years. A-arms LS-7 motor with 6 speed sequential Albins transmission, no clutch, uses a torque converter instead. Car got a little sketchy at 125mph across the desert as air would get under the front end causing it to lift enough to make the steering scary light! Sorry about the sidetrack, off road racing is one of my passions. Householder Class 1.jpg

    I rode a Ural with a sidecar and can't say I cherish the experience.

    As to why build one? I'm getting older and the knees are making it harder and harder to go off-road. So I want a sidecar for more stability and safety. I was leaning towards this type of design:
    [​IMG]

    My ideal requirements:
    • frame as light as possible
    • allow bike to lean (better for off-road riding and can still use the pegs for better control)
    • wheel on sidecar probably 18" for compatibility with the bike (e.g. tube/tyre size, bearings etc).
    • sidecar room to be used for fridge, fuel, etc.
    • sidecar wheel intermittently driven by hydraulic pump (will help in sand when going slow)
    • wheelbase (bike/rack width) about the same, but slightly less than a 4x4 (wheel rut compatibility)
    I haven't seen anything for sale out there that fits the bill

    I don't think a leaner is going to give your knees any relief. :dunno

    I was going to suggest you needed to see FR700's leaner DR 650, he took care of that :-):-)

    Cool looking outfit. Love the body design!! Can you give the masses here what would be examples of 'as and when required' as stated earlier.

    Here is the suspension system that I build for my leaner.
    [​IMG]

    Since a leaner is very sensitive to weight change, I made the suspension adjustable. The damper/spring itself is the same as the bike it's connected to, the length of the swing is also the same.
