    Hi Ian,
    The other bloke is my mate who did the build with me. He rides an FJR1300 and that is the single wheel trailer we built for the trip for him.
    We are planning a side car for the FJR and will start on that later this year. The one we did for my XJR worked well and we should have no great dramas adapting a similar design for his bike.
    That will be a leaner as well so another build thread.
    Cheers

    I heard of the accident a while ago and saw some photo's. The damage to the rig was one thing but what really made me cring was hearing of the nasty injuries your wife sustained. definatly not good when the wife is hurt. So feeling for you both and hope the surgeon was able to screw the wife back together successfully. (I munted my left wrist not long ago as my surgeon said)
    Cheers Bruce.

    Hi Brian,

    just saw this and we are glad that the whole thing turned out reasonably well. Looking at the photos it appears it could have been a whole lot worse. :eek1
    All the best to you and your wife. Hope for a speedy and full revcovery!

    Looking at the design I would say it appears rather well thought out. :wave

    Looking forward to your new build. :lurk

    Just one thing you might want to consider for the new build: How about welding a 45° piece from the front leg underneath chair body to the outer swingarm bearing mounting (instead of the straight pipe with the bend, you shouldn't need the strenght of the bend in that outer part). Such would prevent a possible re-occurance of what happened. Wouldn't it?

    How much ground clearance did you designed for last time? The XJR leaner looks very low compared to the leaner sidecars I know. These usually have about 10 - 15cm depending on the towing bikes.

    Kind regards & speedy, full recovery

    Hi Jens,
    Thanks for your comments.
    We have altered the design of the new chassis so we should not have the same problem again.
    We have found that one characteristic of the leaner is that on a hard right hand corner,(left for you northies) the front of the chassis drops considerably. As you can see by the photo of the XJR1300. I had an extra strong spring made up for that chassis and it still ran low.
    The Roadliner chassis was set at 130mm unladen and runs a progressive shockie for a Suzuki Boulevard. The ride was so comfortable that my wife could sleep in it and it caused no discomfort at all. Until the accident. :evil
    With a load on the sidecar the ride height was probably about 75mm when the wife and luggage were on board. Perhaps the spring rate was too soft, but i think it was more the fact we overloaded the whole thing.
    For the next chassis we will probably look at a loaded height of 130mm or have two fixing points for the shockie allowing for passenger/passenger and load. Maybe with some sort of stop overload.
    Drawings for the new body are complete and i will build this before constructing the chassis. Look out for it in the next few months.
    Cheers

    Perhaps rather than having the frame ending at the front as a blunt edge that is capable of digging in you could carry it forward to curve up into a nudge/ spotlight bar? It would then tend to slid over potential nasties like a sled?
    Then the wife would merely bounce up and land in your lap leading to a happier ending???
    Maybe the last was a bit fanciful :lol3

    :rofl Sounds like a plan.
    That is along the way we are thinking and a reason I want the body built so I can mould the chassis to it.

    My PD is in Bassendean ( at Vinces ) at the moment getting a bit of a resto on it.

    I live SOR in Huntingdale. Going to put my chair onto a GSX14, little horsepower improve over the PD.
