    Rather than piss people off, and "clutter up" the joint with new posts about Sidecars/Hacks/Rigs/Outfits, and since a separate forum does not seem to be materializing, maybe we should confine all sidecar posts, chit-chat, pics, trivia, and question/answer sessions to this one thread.

    It may get confusing, but it will be easier for the old timers to step over 1 thread to read about air heads, than 2 0r 3 at the time:rofl

    Let's give it a shot....if it doesn't work, then this thread can fade into the archives, and all us hackers can locate new digs elsewhere....:freaky

    Screw it. i will continue to post where ever it seems most relevant. I occasionaly do a search"sidecars" to see what I am missing.

    Seems buttheadedly stupid not to have a sidecar forum here, when even scooters, for christsake have their own forum. I have been posting sidecar stuff on ADVrider long enuf for most of my original threads to vaporize with previous upgrades-even a search doesn't find the old stuff anymore:cry
    be a lot easier to find the info if it were in one place.

    Seems all the threads on the topic of hacks are important, just depends on the need at the time. It sure would be nice to be able to search one place.

    All the mods, and it just doesn't end, not like there is a big aftermarket supply. I'm afraid some wisdom will be lost due to "noise".

    I seem to recall someone here referring to a K-bike sidecar project.
    I've been refining ideas for a couple of years, and will start fabrication after the holidays. It would be interesting to compare notes.
    Here are a few nice examples:

    That yelow one reminds me of my Speed Triple (RIP). Man that was a Hooligan Hack! Redlined at 90mph in second gear with the hack!

    Where are you located? I am interested in your project and would love to drop by to see it in process...

    If you are compiling old ADVrider sidecar threads these are some I liked. Hopefully the pix will come back eventually....

    yeah, I know-braggin' agin. But watcha gonna do?

    I used google, search this website, RedMenace to find my old threads. Try the same search string but substitute any ADVrider who has been posting sidecar stuff for longer than a couple of years to recover the older threads here. Doesn't seem to pull up anything much earlier than a couple years back when you use "sidecar' or other subjects rather than a user name...

    I've evaluated numerous Hub center leading arm designs, and would consider this type of suspension the ideal setup for paved surfaces.
    Many of the commercial designs employ hiem pivots, lack satisfactory gusseting or panhard rods, and vary in ease of trail adjustment (where possible at all). The deficits in some of these designs may be related to cost.
    Examples would be the Krauser, Wilbo, RDS, Ruko, Herbig, Saur, Side-bike, Balou, etc... You can google any of those with the word 'sidecar' to get a photo.
    Hannigan has started producing Hub center designs from Balou, and EML also just intoduced a CHS rig as well, so these are catching on.
    There is a small club of enthusiasts who own / discuss these types of rigs at: http://hpsidecars.com/forum/

    My own design is a trellis leading arm with cocentricly located spindle mount for trail adjustment. I presently favor the tie rod steer arrangement over a drag link, but both could be employed if sidecar steering was desired.
    To keep costs down, the top member is an equal length A-arm. These are common off the shelf race car components, as are the ball joints to fit them. A similar, but IMO less attractive design is marketed by Stern Gespanne Service. Shown below:
    [​IMG]

    Making the front supsension integral to the sidecar chassis is a sensible approach, and simplifies construction. The only caveat, is making certain that all suspension members offer adjustability, as the lean-in, toe-in, lead, and trail would all need to be fine tuned. Integral chassis shown below:
    [​IMG]

    In the context of keeping construction cost low, there is the option of using automotive parts in a double A-arm design. One example of source components would be the late model Corvette. Trail adjustability is still possible, and these have recieved positive reviews. Drawbacks to the appraoch are in brake dive, or bump steer. (Negatives high, costs low.)
    This type of construction is currently offered by Mobec:

    I'll try to scan some of the preliminary drawings of my CHS design, but it may take a little while. We recently moved, and half of our posessions are still in boxes. Setting up the new shop space will delay the start of the sidecar project, but I'd like to see it completed by the spring of '08.

    Thats a fun rig. Platform and chair. :bmwrider I agree that the simplest of designs holds much appeal, and the leading link may still be more versatile where the pavement ends. That yellow K100 competion rig is my personal favorite, but doesn't really suit the family travel use that our's would receive.
    We are in Portland. It would be nice to connect with some local enthusiasts. Most of the riders I know are in Seattle. I enjoyed your site BTW. The photos of Aaron flying the chair amused. He and I were room-mates long ago. I have a picture of him driving my old Ambo rig to his high school prom around somewhere... maybe I'll scan and post that one too :D :augie

    Design selection is dependent upon the intended use of a rig. If you plan to spend a lot of time on unimproved roads, you'll want as much ground clearance as possible. That single criteria would probably require using a leading link style fork, where the suspension elements are level with the axle. Most, (but not all) hub center designs have limited ground clearance.
    Just to illustrate the point, and make this post interesting; More eye candy:

    Ruko

    [​IMG]
    Herbig

    [​IMG]
    RDS

    [​IMG]
    Wilbo

    Compare the ground clearance with a typical LL fork, and that might be all the design criteria required. This is an ADV bike forum after all...
    This one is a Merlin HPS LL style rig:
    [​IMG]

    For me, this is a major decision making point. Most of my time will be spent on pavement, but many destinations will be at the end of logging roads, fire roads, or jeep trails. Ultimately, this may force me to build two different rigs. One for pavement, and one for dirt. Thankfully, the K100 is probably too heavy to consider a viable off road platform. This has led to a design compromise. CHS steering can be designed with nearly as much clearance
    as the LL fork. I'll provide some examples in my next post. :stoned
